About this file
This is a bid solicitation and project specification document for the City of Wichita, Kansas Public Works & Utilities Department seeking construction services for the 2026 Outsourced Pavement Preservation Program involving ultrathin bonded asphalt surface (UBAS) overlays. The project encompasses six separate locations totaling approximately 131,002 square yards of pavement treatment across multiple city districts. The work includes surface preparation activities such as cold milling, inlet hookups, manhole adjustments, and base course work, followed by application of ultrathin bonded asphalt surface in three mix types (Type A, B, and C) with varying specifications. Project locations include Woodland Boulevard (13th to Central), Lincoln Street (Willshire to 127th), West Street (Maple to End of Project), Hoover Road (MacArthur to 35th), West 13th Street North (Tyler to Maize), and McLean Boulevard/Amidon Avenue (15th to 21st). The contractor must comply with Kansas Department of Transportation Special Provisions Section 613 and KDOT Standard Specifications Edition 2015, including comprehensive quality control and testing requirements performed by certified personnel. While specific bid due dates and award dates are not explicitly stated in the provided documentation, the specifications reference pre-construction conferences and require submission of Job Mix Formulas at minimum ten working days before production start.
Pricing for the work will be based on tonnage of HMA Surface (Ultrathin Bonded) delivered and placed, with unit prices for emulsified asphalt (Emulsion Bonding Liquid) and Quality Control Testing measured on a per-ton basis. The contractor bears all costs for quality control testing, laboratory facilities, certified technician personnel, and compliance with specified testing frequencies and procedures; no adjustments to unit pricing will be made for variations in aggregate specific gravity or weight per cubic foot. The City of Wichita has reserved the right to accept or reject any or all bids and may waive formalities to determine the lowest and best bid. Contractors must be currently licensed by the City of Wichita or State of Kansas before purchase orders are issued and must provide appropriate bonding by a surety company authorized to do business in Kansas. The contract is subject to compliance with the City of Wichita Mandatory Contractual Provisions (Exhibit A) and Mandatory Independent Contractor Addendum (Exhibit B), Kansas Cash Basis Law, Budget Law, and all applicable federal, state, and local laws. Materials procurement will require obtaining a Kansas Sales Tax Exemption Certificate from the City Controller's Office prior to commencing work.

Sheet 3 of 12
Take all samples for tests and perform in-place tests at random locations, selected according to the
Contractor’s QCP and at the rates specified in the Sampling and Testing Frequency Chart for UBAS for Quality Control/Quality Assurance Projects in Appendix B, Part V.
g. Pre-Production Testing Requirements.
(1) The Engineer will observe the Contractor obtaining and splitting the pre-production test section samples into 3 representative portions. Each sample set shall consist of enough material for Gmm and ignition burnoff testing.
(2) Determine Gmm, perform ignition burnoff, evaluate the mix gradation and complete calculations.
(3) Provide the KDOT Field Representative with the 2nd sample set. The KDOT Field Representative will determine Gmm, perform ignition burnoff, evaluate the mix gradation and complete calculations.
(4) Retain or provide the 3rd sample set to the KDOT Field or District Materials Representative.
(5) The results of the testing will be compared. If Contractor and KDOT field laboratory test results do not compare favorably, the District Materials Laboratory will test their ⅓ of the sample. KDOT personnel will determine Gmm, perform ignition burnoff, evaluate the mix gradation and complete calculations.
If results are not acceptable to either party, repeat the above steps in subsections 613.2g.(1) through (5) for the Contractor’s Field Laboratory, KDOT’s Field Laboratory, and KDOT’s District Laboratory until the issues may be resolved satisfactorily by all parties.
h. Lot 1 Testing Requirements.
(1) Sequence of Sampling. KDOT field personnel will determine the random truckload for the Contractor for sublots A, B, C and D, and the KDOT verification test.
The verification sample will be sampled and tested by KDOT field personnel. The verification sample shall be randomly taken within the lot and shall not be from the same truckload as selected for the Contractor’s sublot samples A, B, C or D.
Obtain sampling using KT-25 procedure C.1 Plant Discharge or C.2 Truck Bed.
KDOT field personnel will:
• not supply the Contractor the identity of the truckload to be sampled ahead of time;
• notify the Contractor’s laboratory of which truck to sample after the aggregate has left the cold feeds, and before the truck is finished loading; and
• determine whether the split sample will be taken from sublot A or B and notify the Contractor.
(2) Split Samples. The Contractor shall:
• obtain a sample large enough to split 3 ways for testing;
• retain and test ⅓ of the sample;
• supply ⅓ of the sample to the KDOT field laboratory for testing; and
• supply ⅓ of the sample for the KDOT District Materials Laboratory for testing.
(3) Results. At a minimum, compare Gmm, binder content, and film thickness results. The acceptable difference for the Gmm results is 0.019. If the results exceed this difference, take an additional split sample in Lot 1 from sublot C or D, as time permits.
If test results do not compare favorably, KDOT and the Contractor will investigate the differences in test results together and take appropriate action. The Contractor’s test results will be used for quality control. KDOT Field Laboratory test results and District Materials Laboratory test results will be reported as "information only" samples.
i. Testing Requirements for Lots 2 and Greater.
(1) Take all samples for tests randomly as designated in the approved QCP at the rates specified in Appendix B - Sampling and Testing Frequency Chart, Part V.
Provide the Engineer with the random locations before obtaining the sample. The Engineer reserves the right to generate the random locations. If the Engineer generates the random locations, the Contractor will be notified of which truck to sample after the aggregate has left the cold feeds, and before the truck is finished loading.
(2) Conduct the tests for mixture properties, aggregate gradation and binder content on representative portions of the HMA, quartered from the larger sample of HMA. Take a random sample weighing a minimum of 55 pounds using a method to retain heat to facilitate sample quartering procedures.
(3) Record and document all test results and calculations on data sheets provided by KDOT. Record specific test results on a daily summary sheet provided by KDOT to facilitate the computation of moving test
Sheet 4 of 12 averages. Base moving averages on 3 consecutive test results. Calculations are to be based on the precision displayed on the data sheets. Use "precision displayed" when calculating within Excel. Appendix B - Sampling and Testing Frequency Chart, Part V shows the accuracy to "record to" for the tests listed. Include a description of quality control actions taken (adjustment of cold feed percentages, changes in Job Mix Formulas (JMF), etc.) in the Daily Quality Control Summary Sheet. In addition, post and keep current quality control charts, showing both individual test results and moving average values. As a minimum, plot the single test values on KDOT approved control charts for the mix characteristics shown in TABLE 613-5.
(4) If the Contractor and Engineer agree, the procedures shown for sampling, testing and evaluation of Lot 1 in subsection 613.2h. may be used for any other Lot produced on the project.
j. Corrective Action. In the QCP, identify procedures for notifying the Engineer when corrective measures must be implemented, and for halting production.
k. Non-Conforming Materials. In the QCP, specifically address how non-conforming materials will be controlled and identified. Establish and maintain an effective and positive system for controlling non-complying material, including procedures for its identification, isolation and disposition. Reclaim or rework non-complying materials according to procedures acceptable to the Engineer. This could include removal and replacement of in-place pavement.
Positively identify all non-conforming materials and products to prevent use, shipment and intermingling with complying materials and products. Provide holding areas, mutually agreeable to the Engineer and Contractor.
613.3 MATERIALS
a. Asphalt Binder. Provide Asphalt Binder that complies with DIVISION 1200. Post a legible copy of the latest bill of lading for the Asphalt Binder in the Contractor’s Field Lab. Use the mixing and compaction temperatures shown on the bill of lading; however, the maximum mixing or compaction temperature is 340ºF, unless otherwise approved by the Field Materials Engineer. Notify the Engineer if the mixing or compaction temperature changes.
Provide Emulsion Bonding Liquid (EBL) that complies with DIVISION 1200.
b. Reclaimed Asphalt Pavement (RAP) and Recycled Asphalt Shingles (RAS). Do not use RAP or RAS in the UBAS.
c. Aggregates. Provide aggregates that comply with SECTION 1103.
d. Combined Aggregates. Provide combined aggregates for the mixes required in the Contract Documents as shown in TABLE 613-1.
Mixes may use any combination (except as noted below) of aggregate and mineral filler supplements complying with the applicable requirements in TABLES 1103-1 and 1103-2. When coarse aggregates are blended from 1 or more sources, or if more than 1 type, each source or type shall meet the coarse aggregate properties (CAA, LA Abrasion, and micro-deval) in TABLE 1103-3.
The minimum Uncompacted Void Content of the Fine Aggregate “U” Value, of the combined aggregate is 45%.
The minimum sand equivalency (SE) of the combined aggregates is 45%.
Provide materials with less than 0.5% moisture in the final mixture.
The maximum quantity of crushed steel slag used in the mix is 50% of the total aggregate weight.
No natural sand will be used in the UBAS.
Traveled way mixes shall include:
a minimum of 40% primary aggregate based on total aggregate weight;
a minimum of 50% of the plus No. 4 mesh sieve material in the mixture shall be from the primary aggregate;
a minimum of 45% of the plus No. 8 mesh sieve material in the mixture shall be from the primary aggregate; and
Sheet 5 of 12
Primary aggregates are designated as CS-1 (excluding limestone), CS-2 (excluding limestone), CG, CH-1 and CSSL as described in subsection 1103.2a.(1). Primary aggregate requirements do not apply to the mixture on the shoulder.
e. Contractor Trial Mix Design. A minimum of 10 working days before the start of UBAS production, submit in writing to the DME for review and approval, a proposed JMF for each combination of aggregates. For each JMF submitted, include test data to demonstrate that mixtures complying with each proposed JMF shall have properties specified in TABLE 613-1 for the designated mix type at the Recommended Percent Asphalt (Pbr).
Submit the proposed JMF on forms provided by KDOT. Submit the worksheets used in the design process to include at a minimum the individual coarse aggregate properties listed in TABLE 1103-3, the fine aggregate properties listed in TABLE 1103-4, and the mix properties listed in TABLE 613-2. Contact the DME to determine if additional material is needed for additional design checks.
For each aggregate used in the mix design, determine the specific gravity using KT-6. This may be accomplished while the project is being constructed or anytime during the 12 months preceding the start of construction on a project. If construction has not yet begun, notify the DME 5 working days prior to obtaining the material for the specific gravity test so that companion samples may be obtained at the same time. If construction has already begun on the project, then determine the specific gravity values of the individual aggregates before 10,000 tons of HMA is produced. Provide the test results to the DME within 14 days of sampling the material. If the producer of the aggregate has been required to submit material to KDOT for a new Official Quality test report since the time the Contractor ran the specific gravity tests, then perform KT-6 on the aggregate currently produced.
Do not use the specific gravity values obtained from these tests in the mix design calculations for current projects unless mutually agreeable to both parties. Use the information, as soon as it becomes available, as part of the process to verify and update the “Monthly Hot Mix Aggregate Specific Gravity Values” posted on KDOT’s Internet site.

613.4 CONSTRUCTION REQUIREMENTS
a. Plant Operation. Adjust all plant operations to operate continuously.
(1) Preparation of the Asphalt Binder. Heat the asphalt binder to within a range as specified in SECTION
601. When heating the asphalt binder to the specified temperature, avoid local overheating. At all times, provide a continuous supply of the asphalt binder to the mixer at a uniform temperature. Asphalt binder received from the refinery at temperatures less than 375°F may be used as received, if the requirements regarding the reheating of asphalt binder in SECTION 601 are met.
(a) Commingling of Asphalt Binders. Do not add or commingle asphalt binders from 2 or more sources into a storage tank. If this occurs, the contents of the storage tank are considered contaminated. Do not use the contents of the storage tank on the project, except as follows: It is permissible, at the Contractor’s option, to thoroughly mix the contents of the tank and request sampling of the mixture. Submit the sample to the MRC for testing. Do not use the asphalt binder until approved, and when needed, a new mix design evaluation is completed.
(b) Asphalt Binder Sources. Before changing asphalt binder sources on a project, obtain approval from the DME. A new JMF may be required.
(c) Anti-Strip Additives. If liquid anti-strip additives are added at the Contractor’s plant, install a “totalizer” to monitor the quantity of anti-strip additive being added. The Engineer may approve alternative methods for including anti-strip additives in a batch plant. If added at the plant, the anti-strip will be added in line with the asphalt binder as it is being transferred from the transit unit to the asphalt binder storage tank. Provide a method for the Engineer to monitor the percent of additive being added.
(2) Preparation of Mineral Aggregate. When the mineral aggregate is composed of 2 or more ingredients, combine as shown in the approved JMF.
Temperature Requirements. Dry the aggregate for the mixture and heat to a temperature to obtain an asphalt-aggregate mixture temperature immediately after mixing within the 75 to 150 second Saybolt viscosity range of the asphalt binder used. Obtain the temperature for this viscosity range from the MRC or the Asphalt Binder Producer. No mixing or compaction temperatures are to exceed 340ºF
Sheet 7 of 12 without approval from the Field Materials Engineer. The minimum temperature may be revised by the DME provided it is demonstrated that satisfactory results may be obtained at a lower temperature. In such event, deliver the HMA to the paver at a temperature sufficient to allow the material to be satisfactorily placed and compacted to the specified density and surface tolerance requirements.
(3) Preparation of HMA. Introduce asphalt binder into the prepared aggregate in the proportionate amount determined by the Pbr in the JMF.
(a) Basis of Rejection. HMA will be rejected if the aggregate, as it is discharged from the drum or the pugmill, contains sufficient moisture to cause foaming of the mixture, or if the temperature of the aggregate is such that the asphalt-aggregate mixture temperature is outside the range specified in SECTION 601.
(b) Mixing Time. Operate drum mixers at a rate to provide uniform aggregate coating in a continuous operation. For batch and continuous type plants, the minimum wet mixing time is 40 seconds. In all cases, mix a sufficient time to produce a uniform mixture in which all the aggregate particles are thoroughly coated. On batch plants, begin the timing at the start of the asphalt binder introduction into the pugmill, and end upon the opening of the discharge gate. For continuous flow plants, mixing time in seconds shall equal:
[pugmill dead capacity in pounds] divided by [pugmill output in pounds per second].
(c) Manufacturer’s Specifications. Operate all drying, pumping and mixing equipment within the limits specified by the manufacturer, unless it can be demonstrated to the satisfaction of the Engineer that such limits may be exceeded without detriment to the HMA.
(d) Batcher Operation. Coordinate HMA batchers (Gob Hoppers) with the plant production rate at all times so the hopper is more than ¾ full before the gates open, and the gates close before material can drop through the gob hopper directly into the surge bin, weigh hopper or truck.
(e) Wasted Material. Wasted material is not measured for pay.
If after an interruption of production, the drum-mixer contains cold, uncoated or otherwise unsuitable material, waste material through a diversion chute. In a continuous or batch plant drier, waste unsuitable material through the pugmill.
At the end of a production run, waste any segregated material in the cone of the storage bin.
(4) End of Day Quantities. At the end of each day of production, provide the Engineer with a document signed by the Plant Foreman or the Project Manager listing the dry weight of each aggregate and mineral filler; the tons of asphalt binder, and the tons of anti-strip agent used for the project during the day. The dry weight is the tons of the material less the water content.
b. Road Surface Preparation.
(1) Preparation of an Existing Asphalt Pavement. Clean the surface to remove all foreign material and broom to remove dust. Excavate areas shown in the Contract Documents to be patched to a depth directed by the Engineer. Fill with HMA and compact.
(2) Preparation of an Existing Concrete or Brick Pavement. Clean all foreign material and broom to remove dust. Clean and fill cracks and joints, and construct surface leveling as shown in the Contract Documents.
c. Weighing Operations. See subsection 109.1 for details regarding weighing operations.
d. Hauling Operations. Schedule operations to minimize hauling over a surface course.
Deliver HMA to the paver at a temperature sufficient to allow the material to be placed and compacted to the specified density and surface tolerance.
e. Paving Operations.
(1) Equipment Use a transfer device between the haul units and the paver to assist in maintaining continuous placement. Use equipment such as a shuttle buggy, material transfer vehicle or mobile conveyor. (The material will not be deposited on the roadway and a pick-up device used to transfer the material to the paver.)
Use a self-priming paver, designed and built for applying the UBAS and approved by the Engineer.
Use a paver with the following requirements:
with a receiving hopper, feed conveyor, asphalt emulsion storage tank, a system for measuring the
EBL volume applied, a spray bar, and a heated, variable width, vibratory screed;
Sheet 8 of 12 capable of spraying the EBL, applying the hot mix surface course and leveling the surface of the mat in one pass;
capable of placing the hot mix surface course within 5 seconds after the application of the EBL;
capable of paving at a controlled speed from 30-100 feet/minute;
equipped so no wheel or other part of the paving machine is in contact with the EBL before the hot mix surface course is applied; and equip the screed with the ability to crown the pavement at the center and have vertically adjusted extensions to accommodate the desired pavement profile.
The Engineer will check the pavement for longitudinal streaks and other irregularities. Make every effort to prevent or correct any irregularities in the pavement, such as changing pavers or using different and additional equipment.
Do not raise (dump) the wings of the paver receiving hopper at any time during the paving operation.
(2) Application: Spray the EBL by a metered mechanical pressure spray bar at the temperature specified in TABLE 601-1, or as recommended by the EBL supplier. Use a sprayer that accurately and continuously monitors the rate of spray and provides a uniform application across the entire width to be overlaid. The Engineer may make adjustments to the spray rate based upon the existing pavement surface conditions and the recommendations of the EBL supplier.
Apply the UBAS at a temperature of 290-330ºF and spread over the EBL immediately after the application of the EBL. Place the UBAS over the full width of the EBL with a heated vibratory screed. Adjust the screed and its extensions to eliminate variances in surface texture caused by density segregation. Operate the paver as continuous as possible to reduce the possibility of screed indentations in the finished mat.
The target application rate of the UBAS will be stated in the Contract Documents. Use a field application rate as necessary to minimize fracturing of the top size aggregate by the screed. The Engineer will determine the acceptable extent of fracturing at the edge of the paving for tapering purposes.
The finished asphalt surface shall be free of oversized material. The Engineer will determine the extent of the oversized material in the UBAS. Take immediate corrective action to eliminate the source. If the source of the oversized material is determined to be a stockpile or a process of plant operations, cease production until corrective actions are complete.
Spread the UBAS without tearing the surface. Strike a finish that is smooth, free of segregation, true to cross section, uniform in density and texture and free from surface irregularities. If the pavement does not comply with all of these requirements, plant production and paving will be suspended until the deficiency is corrected.
(3) Compaction: Roll the UBAS with a minimum of 1 pass and a maximum of 3 passes with 2-axle tandem steel rollers having a minimum weight of 10 tons, before the material temperature has fallen below 195ºF. The Engineer will determine the number of passes necessary based on appearance of the rolled material. Do not allow the roller or rollers to remain stationary on the freshly placed UBAS. Perform rolling immediately following the placement of the UBAS with approved asphalt rollers. Supply adequate roller units so the rolling will be accomplished promptly following the placement of the material. A release agent (added to the water system) may be required to prevent adhesion of the fresh mix to the roller drum and wheels. Normally, perform rolling in the static mode. Do not excessively roll the driving lanes, to the extent of aggregate degradation. The Engineer will determine the acceptable extent of fracturing at the edge of the pavement from the rolling operation. Do not open the new pavement to traffic or allow any roller to sit idle on the pavement until the rolling operation is complete and the material has cooled below 160°F.
Damaged Areas: Replace any defective areas, as determined by the Engineer, at no additional cost to
KDOT.
(4) Construction Joints.
Transverse Construction Joints. Use a method of making transverse construction joints which provide a thorough and continuous bond and provide an acceptable surface texture. Do not vary the surface elevation more than 3/16 inch in 10 feet, when tested longitudinally across the joint. When required, repair the joints or paving operations will be suspended.
Longitudinal Joints. Construct well bonded and sealed longitudinal joints to obtain maximum compaction at the joint.
(5) Adjustment of Manholes (Set Price). When required, this work will be performed and paid for under
SECTION 816.
Sheet 9 of 12
f. Maintenance of Traffic. Maintain traffic according to DIVISION 800 and the following:
Maintain one-way traffic, and restrict traffic speeds to 20 miles per hour in the vicinity of workers, unless otherwise designated. Use pilot cars to lead traffic through the area of paving and rolling operations, and if directed, through a curing area. The use of flaggers is allowed through patching operations, unless the patching area or distance between flaggers exceeds ½ mile, in which case the use of a pilot car shall be required. On overlay projects with 2 lanes or more in each direction for traffic use, the Engineer may waive the pilot car requirements.
Station one flagger ahead of the application of the tack coat and one flagger ahead of the area being protected from traffic. Take adequate protection for traffic on side roads approaching the tack area.
g. Treatment of Adjacent Areas. Pave sideroads, entrances and turnouts for mailboxes as shown in the Contract Documents. Overlay all widening areas designated in the Contract Documents or ordered by the Engineer.
h. Pavement Smoothness. UBAS is excluded from profilograph testing, and not eligible for pay adjustments.
613.5 PROCESS CONTROL
a. General. Establish gradation limits and proportions for each individual aggregate and mineral filler.
Specify the limits and proportions such that the material produced complies with the applicable requirements of the designated mix type. The Contractor is responsible for all process control operations including testing. At no time will KDOT’s representative issue instructions to the Contractor or producer as to setting of dials, gauges, scales and meters. KDOT will collect and test verification samples and assurance samples and inspect the Contractor’s quality control operations.
b. JMF Adjustments. Produce a mixture of uniform composition closely complying with approved design JMF to obtain the specified properties when compacted. If, during production, results from quality control tests demonstrate a need to make adjustments to the mix design, then make adjustments to the design JMF single point gradation and binder content to achieve the specified properties. The JMF adjustments shall produce a mix that complies with TABLE 613-1 for the specified mix designation. When necessary, adjust on a sublot basis. Report the new JMF to KDOT’s field representative and the DME before making such changes, and submit a new mix design for review and approval if required by the DME.
c. Specification Working Ranges. Establish acceptable limits for field test results by applying the tolerances shown in TABLE 613-5 to the JMF or adjusted JMF for binder content. Establish acceptable limits for the other listed mix characteristics by applying the tolerances shown in TABLE 613-5 to the requirements of
TABLE 613-1.

d. EBL Shot Rate Specification. Periodically determine the application rate of the EBL. The Engineer will verify the application rate. Acceptable tolerance of the application rate is the target rate ±0.02 gal/sq yd. Check for proper coverage at least twice per day by applying the EBL to the road surface for a minimum distance of 20 feet. When the Engineer verifies the coverage meets specification, back up the paver and shoot not more than 1/4 of the EBL shot rate over the previously tacked segment.
613.6 WEATHER LIMITATIONS
Do not place UBAS on any wet or frozen surface or when weather conditions otherwise prevent the proper handling and finishing of the mixture.
Only place UBAS when either the minimum ambient air temperature is 50oF or the minimum road surface temperature is 55oF.
613.7 MIXTURE ACCEPTANCE
a. General. Test the UBAS at each plant for compliance with TABLE 613-1. Acceptance will be made on a lot by lot basis contingent upon satisfactory test results. Obtain quality control and verification samples of the UBAS using KT-25 sampling procedure C.1 Plant Discharge or C.2 Truck Bed.
A load or loads of mixture which, in the opinion of the Engineer, are unacceptable for reasons such as being segregated, aggregate being improperly coated, foaming aggregate or being outside the mixing temperature range may be rejected.
b. Lot Definition for Mix Production Sampling and Testing. A lot is defined as an isolated quantity of a specified material produced from a single source or operation. Each lot shall normally be represented by 4 contiguous test results. A lot may be represented by test results on samples taken from 1 or more day’s production.
c. Lot Investigation. The Engineer may examine materials represented by individual test results which lie beyond the Contractor’s normal quality control testing variation. The investigation may be based on either Contractor or KDOT test results. The information from additional testing (including testing of in-place HMA) may be used to define unacceptable work according to SECTION 105. The Engineer may apply appropriate price reductions or initiate corrective action.
For any test, if a dispute exists between the Engineer and Contractor about the validity of the other’s test results, the KDOT District Materials Laboratory or the MRC will perform referee testing. If the disputed KDOT test results were generated at the District Laboratory, the MRC will perform the referee tests. If the disputed KDOT test result was generated at the MRC, an independent laboratory agreeable to both parties will be selected. The Laboratory shall be accredited by the AASHTO Accreditation Program in the appropriate testing category.
If referee testing indicates that KDOT test results are correct, the Contractor pays for the additional testing, including referee testing performed at the MRC. This will be paid using the bid item Contract Deduct which will be an item added to the contract.
If the referee testing indicates that Contractor test results are correct, KDOT pays for the additional testing.
Pay the independent lab for the testing and submit the paid invoice to KDOT. The Engineer will reimburse the Contractor (based on the invoice price) as Extra Work, SECTION 104.
d. Multiple Projects. If multiple projects are supplied from 1 or more plants using the same mix, carry over the lots at each hot mix plant from project to project.
e. Lot Size. A standard size mix production lot consists of 4 equal sublots of 400 tons each of asphalt mixture (lot size 1,600 tons). If the last sublot contains less than 200 tons, combine it with the previous sublot.
Sheet 11 of 12
It is anticipated that lot size shall be as specified. However, with the Engineer’s approval, the Contractor may re-define lot size for reasons such as, but not limited to, change in contract quantities or interruption of the work.
