The bond coat material will be emulsified asphalt conforming to the requirements of Section 904 of the Michigan Department of Transportation (MDOT) 2012 Standard Specifications for Construction, Type SS1h. 2. HMA Ultra-thin Overlay. The Ultra thin HMA Overlay shall be composed of a mixture of aggregate, asphalt binder, and if required, mineral filler, as listed in Table 1. Table 1 - HMA Ultra-thin Overlay Mixture Requirements Low Volume Medium Volume < High Volume >3400 Parameter Marshall Air Voids % VMA % (min.) based on Gsb Fines/Binder % Max Flow (0.01 in.) Stability Min. (lbs) Aggregate Gradation and Physical Properties. The combined gradation of the aggregate portion of the mixture, including the mineral filler, shall be within the limits of Table 2. The physical properties of the combined aggregates shall meet the criteria of Table 3.

AWI of 220 is required for projects with less than or equal to 2000 ADT, projects with ADT greater than 2000 the minimum AWI requirement is 260. In addition, the sum of the shale, siltstone, ochre, coal, clay-ironstone and particles which are structurally weak or are found to be non-durable in service shall not exceed 8.0 percent. 4. Performance Graded (PG) Asphalt Binder. Binder selection is based on present day two-way commercial ADT as listed in Table 4. The PG binder shall meet all the requirements in Section 904 of the MDOT 2012 Standard Specifications for Construction. Table 4 - Asphalt Binder Selection for HMA Ultra-thin Overlay Low Volume <380 Medium Volume High Volume >3400 PG PG 64-28P PG 70-22P c. Construction. 1. Bond Coat Application. The bond coat material will be applied to completely cover the prepared surface at a rate of gal/syd. 2. Mixture Application Rate. The target application rate shall be 85 lb/syd, unless specified by the engineer to address special circumstances. 3. Mix Design. The Contractor shall submit to the Owner a complete mix design for review prior to the start of production. 4. Quality Control. The Contractor shall provide and follow a Quality Control (QC) plan for the Ultra thin HMA Overlay that will maintain adequate QC for production and construction processes applicable to this specification and the contract documents. For QC purposes, the Contractor must perform at least one QC test per day for gradation, AC content, and air voids, and is allowed to take informational cores for application rates. The Owner shall be provided a copy of the QC plan for review, prior to mix production and placement. After the job-mix-formula is established, the aggregate gradation and the binder content of the HMA mixture furnished for the work shall be maintained within the Range 1 uniformity tolerance limits permitted for the job-mix-formula specified in Table 5. However, if deviations are predominantly either below or above the job-mix-formula, the Owner may order alterations in the plant to bring the mixture to the job-mix-formula. If two consecutive aggregate gradations on one sieve, or binder contents as determined by the QC tests, are outside Range1 but within Range 2 tolerance limits, the Contractor shall suspend all

12 operations. Contract time will continue during these times when the plant is down. Before resuming any production, the Contractor shall propose, for the Owner s approval, all necessary alterations to the materials or plant so that the job-mix-formula can be maintained. The Owner, after evaluating for effects on AWI and mix design properties, will approve or disapprove such alterations. Additionally if any one test, Contractor or Owner, indicates the Binder Content is more than 0.10% below the job-mix-formula, the Contractor shall suspend all operations. Before resuming any production, the Contractor shall propose, for the Owner s approval, all necessary alterations to the materials or plant so that the job-mix-formula can be maintained. Table 5 Uniformity Tolerance Limits (for QC and Acceptance) PARAMETER * Range 1 Range 2 Air Voids** ± 1.0 ± 2.0 Binder Content ± 0.40 ± 0.50 % Passing # 8 and Larger Sieves ± 5.0 ± 8.0 % Passing # 30 Sieve ± 4.0 ± 6.0 % Passing # 200 Sieve ± 1.0 ± 2.0 * This range allows for normal mixture and testing variations. The mixture shall be proportioned to test as closely as possible to the Job-Mix-Formula. ** Air Void limits apply to QC testing and are optional for Acceptance testing. 5. Crushed Particle Content. The crushed particle content of the aggregate used in the HMA mixture shall not be more than 10 percentage points above or below the crushed particle content used in the job-mix-formula nor less than the minimum specified for the aggregate in the project documents. 6. Density. Thoroughly compact the mixture immediately after placement using the number of rollers method. i. Number of Rollers Method. The number of compactive and finish rollers used shall be as specified in Table 6 based on the square yards per hour of Ultra thin HMA Overlay being placed. Table 6 Number of Rollers Required based on Placement Rate Average Laydown Number of Rollers Required Rate, square yards per hour Compaction Rollers Finish Rollers Less than * and more 4 1 *The compaction roller may be used as the finish roller also. d. Acceptance Sampling and Testing. Acceptance sampling and testing may be performed by the Owner. Each day of production, a minimum of two samples will be obtained for each mix type. Acceptance testing will be performed at the frequency specified by the Owner. No less than three samples shall be obtained for each mix type.

13 e. Rejected Mixtures. If for any one mixture, two consecutive aggregate gradations on one sieve or binder contents as determined by acceptance tests exceed the uniformity tolerance of Range 2 under Table 5, or do not meet the minimum requirements for crushed particle content specified in the project documents, the mixture will be rejected. If such mixtures are placed in a pavement, the remaining portions of the failing acceptance samples (split sample) will be sent to an independent Laboratory to confirm the acceptance test results. If the Laboratory s results do not confirm the acceptance test results, then no price adjustments will be made for the mixture involved. If the Laboratory s results confirm the acceptance test results and if, in the Owner s judgment, the defective mixture can remain in place, the contract unit price for the defective mixture involved, as determined from acceptance tests, will be decreased on the following basis: The contract unit price for material outside of Range 2 will be decreased 25 percent. The Owner may take into account the Contractor s QC test results when making acceptance decisions and price adjustments. f. Measurement and Payment. The completed work as measured will be paid for at the contract unit price for the following contract item: Contract Item (Pay Item) HMA, Ultra-thin, Medium Volume Pay Unit Ton Payment for HMA, Ultra-thin, Medium Volume, includes all materials, equipment, labor for preparing the surface, placing the HMA, Ultra-thin Overlay mixture and complying with all requirements. The placement includes placement of a single course of mixture for full width coverage as specified in the plans.
