106 - Acceptance of Work 106.01_National_7_18_2017

Delete Subsection 106.01 and replace with the following:

106.01 Conformity with Contract Requirements.

Follow the requirements of FAR Clause 52.246-12 Inspection of Construction.

References to standard test methods of AASHTO, ASTM, GSA, and other recognized standard authorities refer to the methods in effect on the date of solicitation for bids.

Perform all work to the lines, grades, cross-sections, dimensions, and processes or material requirements shown on the plans or specified in the contract.

Incorporate manufactured materials into the work according to the manufacturer’s recommendations or to these specifications, whichever is more strict.

Plan dimensions and contract specification values are the values to be strived for and complied with as the design values from which any deviations are allowed. Perform work and provide material that is uniform in character and reasonably close to the prescribed value or within the specified tolerance range. The purpose of a tolerance range is to accommodate occasional minor variations from the median zone that are unavoidable for practical reasons.

When standard manufactured items are specified (such as fence, wire, plates, rolled shapes, pipe conduits, etc., that are identified by gauge, unit mass, section dimensions, etc.), the identification will be considered to be nominal masses or dimensions. Unless specific contract tolerances are noted, established manufacturing tolerances will be accepted.

The Government may inspect, sample, or test all work at any time before final acceptance of the project.

When the Government tests work, copies of test reports are furnished to the Contractor upon request.

Government tests may or may not be performed at the work site. If Contractor testing and inspection is verified by the Government, the Contractor’s results may be used by the Government to evaluate work for acceptance. Do not rely on the availability of Government test results for process control.

Acceptable work conforming to the contract will be paid for at the contract unit bid price. Four methods of determining conformity and accepting work are described in Subsections 106.02 to 106.05 inclusive.

The primary method of acceptance is specified in each Section of work. However, work may be rejected at any time it is found by any of the methods not to comply with the contract.

Remove, repair, or replace work that does not conform to the contract, or to prevailing industry standards where no specific contract requirements are noted. Removing, repairing, or replacing work;

providing temporary traffic control; and any other related work to accomplish conformity will be at no cost to the Government.

(a) Disputing Government test results. If the accuracy of Government test results is disputed, promptly inform the CO. If the dispute is unresolved after reasonable steps are taken to resolve the dispute, further evaluation may be obtained by written request. Include a narrative describing the dispute and a proposed resolution protocol that addresses the following:

1. Sampling method;

2. Number of samples;

3. Sample transport;

4. Test procedures;

5. Testing laboratories;

6. Reporting;

7. Estimated time and costs; and

8. Validation process.

If the evaluation requires additional sampling or testing be performed, mutually agree with the Government on witnessing procedures and on sampling and testing by a third party laboratory. Use a third party laboratory accredited by the AASHTO accreditation program. Provide proof of the laboratory’s accreditation for the test procedures to be used. Do not use the same laboratory that produced the disputed Government test results or that produced the test results used as a basis for the dispute.

The CO will review the proposed resolution protocol and may modify it before final approval and execution.

The Government will use the approved resolution protocol test results to determine the validity of the disputed testing. If the Government test results are validated, the Contractor will be responsible for all costs associated with developing and performing the resolution protocol. If the Government test results are not validated, the Government will be responsible for all costs associated with developing and performing the resolution protocol. If the validity of the Government test results cannot be determined, the Contractor and Government will equally share all costs associated with developing and carrying out the resolution protocol.

(b) Alternatives to removing and replacing non-conforming work. As an alternative to removal and replacement, the Contractor may submit a written request to:

1. Have the work accepted at a reduced price; or

2. Be given permission to perform corrective measures to bring the work into conformity.

The request must contain supporting rationale and documentation. Include references or data justifying the proposal based on an evaluation of test results, effect on service life, value of material or work, quality, aesthetics, and other tangible engineering basis. The CO will determine disposition of the nonconforming work.

Material

414.02 Conform to the following Section and Subsection:

Asphalt concrete 403 Joint sealants and crack fillers (hot applied) 712.01(a)

Equivalent material conforming to WisDOT Highway and Structure Specification 475 may be substituted with prior CO approval.

Construction Requirements

414.03 Equipment. Furnish equipment with the following capabilities:

(a) Router. A power rotary impact router or vertical spindle router capable of creating a reservoir to the required depth and width without damaging adjacent pavement.

(b) Air lance. A hot compressed air lance capable of providing clean, oil-free compressed air at a volume of 100 cubic feet (2.8 cubic meters) per minute, a pressure of 120 pounds per square inch (830 kilopascals), and a temperature of 2000 °F (1100 °C).

(c) Application wand. A wand attached to a heated hose attached to a heated material chamber that maintains material temperature within manufacturer’s tolerances. Supply proper wand tips for desired application.

(d) Heating kettle. An indirect-heating double boiler capable of constant and effective agitation. Fill the space between the inner and outer shells with oil or other heat transfer medium. Provide an accurate and calibrated thermometer with a range from 200 to 600 °F in 5 °F graduations (90 to 320 °C in 2 °C graduations) located so the material temperature can be safely checked.

(e) Squeegee or screed. A hand-held squeegee or screed of appropriate configuration for filling cracks flush with the surface, underfilling cracks to recess below the surface, or overfilling cracks to an overband shape.

(f) Compressor. A compressor capable of producing oil- and water-free air at a minimum rate of 100 cubic feet (2.8 cubic meters) per minute with a minimum continuous line pressure of 125 pounds per square inch (860 kilopascals).

414.04 Routing. Rout, clean, and seal cracks in a continuous operation. Do not allow traffic to close or damage routed cracks.

Rout ⅛- to ½-inch (3- to 13-millimeter) wide cracks to produce vertical, intact walls and a flat bottom with a reservoir centered over the crack. Make the reservoir two to three times the width of the crack.

Rout cracks to a depth of ½ to ¾ inches (13 to 19 millimeters).

414.05 Cleaning. Prevent debris from entering waterways, travel lanes open to public traffic, or areas designated not to be disturbed. Remove dirt, dust, and other deleterious material from the crack walls and cavity using a stream of air or other approved methods. Blow or brush dry material off the pavement surface.

414.06 Sealing and Filling. Dry the crack surfaces with the hot air lance before sealing or filling.

Do not seal or fill cracks when the pavement surface temperature is below 35 °F (2 °C) and weather conditions are rainy or foggy.

(a) Sealing (routed cracks or cracks averaging ¼ to 1 inch (6 to 25 millimeters) wide).

Submit a copy of and adhere to the manufacturer’s recommendations for heating and applying the hot applied crack material. Heat the material to pouring temperature in a heating kettle and continuously agitate the material.

Discard sealant when:

(1) Heated above the safe heating temperature recommended by the manufacturer;

(2) Held at pouring temperature for more than 12 hours;

(3) Reheated more than once; or

(4) Not consistent or uniform in appearance.

Warm and dry the crack surfaces using a hot-compressed air lance if the pavement temperature is lower than 50 °F (10 °C) or moisture is present. Keep the lance moving to prevent burning the pavement surface. Place and finish the material within 5 minutes after heating the pavement surface with the lance.

Use an application wand to place material in each crack from the bottom up. Insulate the wand to maintain pouring temperature while placing material. Return the wand to the heating kettle immediately after sealing each crack. Use a squeegee or screed to strike off the material.

(b) Filling (cracks averaging more than 1 inch (25 millimeters) wide). Fill each crack with an asphalt mix according to Section 403. Use a squeegee, screed, or other suitable equipment to force the mix into the crack. Fill each crack flush with the pavement surface and compact the asphalt mixture.

Do not allow traffic on sealed or filled cracks until the sealant or filler has cured or is treated with debonding material recommended by the manufacturer and approved by the CO.

414.07 Resealing Cracks. Reseal cracks exhibiting adhesion failure, damage, incomplete filling, foreign objects in the sealant, or otherwise rejected by the CO.

414.08 Acceptance. Material for asphalt pavement crack sealing or filling will be evaluated under Subsections 106.02 and 106.03.

Asphalt pavement crack sealing and filling will be evaluated under Subsections 106.02 and 106.04.
