1. When using a PG 76-22 asphalt binder in friction course mixtures, limit the amount of RAP material used in the mix to a maximum of 20% by weight of total aggregate. As an exception, amounts greater than 20% RAP by weight of total aggregate can be used if no more than 20% by weight of the total asphalt binder comes from the RAP material. When using a PG 76-22 asphalt binder in structural course mixtures, refer to 334-2.3.6. RAP is not allowed in mixtures containing High Polymer asphalt binder. High Polymer asphalt is defined in Section 916.

2. Assume full responsibility for the design, production and construction of asphalt mixes which incorporate RAP as a component material.

3. Use RAP from a Department approved stockpile or millings from a Department project.

4. Provide stockpiled RAP material that is reasonably consistent in characteristics and contains no aggregate particles which are soft or conglomerates of fines.

5. Provide RAP material having a minimum average asphalt binder content of 4.0% by weight of RAP. As an exception, when using fractionated RAP, the minimum average asphalt binder content for the coarse portion of the RAP shall be 2.5% by weight of the coarse portion of the RAP. The coarse portion of the RAP shall be the portion of the RAP retained on the No.

4 sieve. The Engineer may sample the stockpiles to verify that this requirement is met.

6. Amounts greater than 25% RAP by weight of total aggregate are prohibited unless specifically authorized by the Engineer. If the Engineer allows RAP to exceed 25%, the limitations in the section and specifically tables 334-2 and 334-3 will still apply.

334-5.1.2 Acceptance Testing Exceptions:

The mixture quantity in the first paragraph is amended as follows:

When the total combined quantity of hot mix asphalt for the project or work order, as indicated in the Plans for Type B-12.5, Type SP and Type FC mixtures only, is less than two hundred (200) tons, the Engineer will accept the mix on the basis of visual inspection.

334-5.2 Full LOTs:

A LOT is that amount of material which is evaluated for pay purposes. Each LOT is evaluated as a separate project based on results from a specified number of random samples, and each day’s production will be divided into LOTs. The standard size of a LOT will consist of five thousand (5000) feet of any pass on each separate lift made by the paving train regardless of the width of the pass or the thickness of the course.

The size of any given LOT may vary according to that day’s production based on the following:

1. If the day’s production is less than or equal to seven thousand (7000) feet, the entire day’s production will be considered one LOT.

2. If the day’s production is greater than seven thousand (7000) feet, the first five thousand (5000) feet shall be considered one LOT, and the remaining production (up to an additional 7000 feet) will be considered a second LOT.

3. If the day’s production is greater than twelve thousand (12,000) feet, the first five thousand (5000) feet shall be considered one LOT, the second five thousand (5000) feet shall be considered a second LOT, and the remaining production (up to an additional 7000') will be considered a third LOT.

Whether due to miscommunication, plant breakdown, extreme weather, or other events beyond control, there may be instances when only one sample of the plant produced mix may be obtained on a day’s production that exceeds more than one LOT. When this occurs, the test data from that sample will be used for all LOTs on that day. If the mix design or type is changed during the day’s production, a new LOT will be established.

In most cases, all LOTs are to be closed out at the end of each day. However, in some instances, at the direction of the Engineer, it may be necessary or practical to take two small LOTs produced on consecutive days and combine them into one LOT. If LOTs are combined over two production days, a hot mix sample must be taken from each day and cores must be identified by day’s production to ensure use of proper GMM when determining density of cores.

334-5.4.3 Roadway Sampling and Testing Requirements:

The average density of each LOT shall be determined by randomly located core samples obtained by the Contractor under the supervision of the COUNTY’S Inspector or duly authorized representative at locations designated by the COUNTY. The COUNTY Inspector should be present to witness the Contractor’s coring operation. In no case shall the Contractor core the asphaltic concrete pavement unless specifically authorized by the Engineer or the County’s Inspector. If the pavement is cored by the Contractor without authorization from the Engineer, the Engineer shall either require that the LOT section be removed and replaced at the cost of the Contractor, or accepted at no cost to the COUNTY, or accepted at a reduced rate as determined by the Engineer.

The COUNTY may elect to obtain the core samples using their authorized testing laboratory. The LOT size shall be the same as that indicated in 334-5.2.

Core samples shall be neatly cut with a core drill. The cutting edge of the core drill bit shall be of hardened steel or other suitable material with diamond chips embedded in the metal cutting edge.

The standard diameter of the sample shall be six (6) inches. The standard core size for thickness ONLY determination will be two (2) inches. Care should be exercised while retrieving, transporting, or storing the core that the sample is not distorted, bent, cracked or in any way changed from its physical condition as it was before removal from the pavement. Two (2) core samples taken approximately within one foot of each other shall be obtained at each designated location specifically marked in the field by the Engineer with the exception of recreational trails, parks, and public parking areas where one (1) 4” core sample shall be taken at each location. Additional cores adjacent to the initial core may be taken as referee cores if results are disputed but only with authorization of the Engineer. Under no circumstances will the Contractor be allowed to adjust the designated core locations based on non-destructive density readings taken prior to the cutting of the cores. No additional cores shall be cut by the Contractor, unless specifically authorized by the Engineer.

The Engineer may elect to obtain only one core per location at the initial sampling and obtain the verification core only if needed at a later date. Samples that are clearly defective, as a result of sampling, shall be discarded and another sample immediately taken within approximately one (1) foot of the original location at the direction of the County. The Contractor shall furnish all tools, labor, materials, and traffic control for cutting samples and filling the cored pavement. The Contractor is required to cut as many cores as the Engineer deems necessary to evaluate the pavement LOT for acceptance purposes. In certain instances, the Engineer may require the Contractor to cut a third core from each location in a LOT for permeability testing. The Contractor shall furnish sample containers of sufficient strength to prevent cores from being damaged during transport and the core specimens shall be secured with masking tape. Once all the cores for a particular LOT have been obtained, they shall be immediately transferred to the COUNTY Inspector.

Cores should be cut on day of paving. However, in the event of equipment malfunction or inclement weather, the cores shall be taken as soon as practicable on the next regular workday.

The Contractor shall cut a minimum of three (3) core locations per LOT with smaller LOTs prorated by length. All cores will be taken at random locations selected by Pinellas County using Core Random Sampling chart – see Table 334-5.4.3 below.

Acceptance of the compacted pavement with respect to density will be based on the average of each LOT’s core samples tested in accordance with Florida Test Method FM 1-T 166. Cores taken in turn outs, cul-de-sacs or streets less than 100 feet in length will be for information only with no incentive or disincentive adjustment and will not be considered part of the three (3) core minimum.

334-5.4.3.1 Authorization To Core:

No cores shall be cut in the asphalt pavement unless previously authorized by the COUNTY.

If the Contractor cuts cores from a LOT without authorization from the COUNTY, the Engineer shall either require that the LOT section be removed and replaced at the cost of the Contractor, or accepted at no cost to the COUNTY, or accepted at a reduced rate as determined by the Engineer.

334-5.4.3.2 Final Density Determination:

Once the average density of a LOT has been determined the Contractor will not be permitted to provide additional compaction to raise the average.

334-5.4.3.3 Authorization To Pave Final Lift:

For new construction with multiple lifts or full depth asphalt base with structural and final lift or friction course, the Contractor shall not construct the final surface course of pavement until receipt of written authorization from the Engineer to proceed with paving. If the final surface course of pavement is installed without written authorization from the Engineer, the Engineer shall either require that the LOT section be removed and replaced at the cost of the Contractor, or accepted at no cost to the COUNTY, or accepted at a reduced rate as determined by the Engineer.

334-8.3 Density Requirements and Adjustment:

334-8.3.1 General Construction:

After final compaction, the pavement shall have an average density equivalent to at least ninety-two (92%) percent of the Maximum Specific Gravity (Gmm) of the paving mixture for that LOT 's production as determined by Section 334-5.1.1. Once the average density of a LOT has been determined, the Contractor will not be permitted to provide additional compaction to raise the average. If the average density is less than 92% of the Maximum Specific Gravity (Gmm), then the mix will be accepted at a reduced price as determined by the Engineer in accordance with the requirements of this Section and Table 334-8.3.1.

334-8.3.2 Overlay Construction:

The following specification is applicable only for overlay construction of existing pavement to include milled surfaces and milled surfaces with exposed base. After final compaction, the pavement shall have an average density equivalent to at least ninety point five (90.5%) percent of the Maximum Specific Gravity (Gmm) of the paving mixture for that LOTs production as determined by Section 334-5.1.1. Once the average density of a LOT has been determined, the Contractor will not be permitted to provide additional compaction to raise the average. If the average density is less than 90.5% of the Maximum Specific Gravity (Gmm), then the mix will be accepted at a reduced price as determined by the Engineer in accordance with the requirements of this Section and Table 334-8.3.1.
