I 1 sample will not be tested with the same tester that ran the original acceptance test. The I 2 sample will be tested for a complete gradation analysis, asphalt binder content, and, at 3 the option of the agency, Va. The results of the retest will be used for the acceptance of 4 the HMA in place of the original sublot sample test results. The cost of testing will be I 5 6 deducted from any monies due or that may come due the Contractor under the Contract at the rate of$500 per sample. 7 I8 5-04.3(9)D Mixture Acceptance — Commercial Evaluation 9 If sampled and tested, HMA produced under Commercial Evaluation and having all 10 constituents falling within the tolerance limits of the job mix formula shall be accepted at 11 the unit Contract price with no further evaluation. When one or more constituents fall 12 outside the commercial tolerance limits in the Job Mix Formula shown in 5-04.3(9), the 13 lot shall be evaluated in accordance with Section 1-06.2 to determine the appropriate I 14 CPF. The commercial tolerance limits will be used in the calculation of the CPF and the 15 maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the 16 existing sublots or samples from the street shall be tested to provide a minimum of three I 17 sets of results for evaluation. 18 19 For each lot of HMA mix produced and tested under Commercial Evaluation when the I 20 calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be 21 determined. The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 22 60 percent. The Job Mix Compliance Price Adjustment will be calculated as the product I 23 of the NCMF, the quantity of HMA in the lot in tons, and the unit Contract price per ton of 24 mix. 25 I 26 If a constituent is not measured in accordance with these Specifications, its individual 27 pay factor will be considered 1.00 in calculating the Composite Pay Factor(CPF). 28 I 29 5-04.3(10) HMA Compaction Acceptance 30 HMA mixture accepted by nonstatistical evaluation that is used in traffic lanes, including 31 lanes for intersections, ramps, truck climbing, weaving, and speed change, and having a I 32 specified compacted course thickness greater than 0.10-foot, shall be compacted to a 33 specified level of relative density. The specified level of relative density shall be a 34 Composite Pay Factor (CPF) of not less than 0.75 when evaluated in accordance with I 35 Section 1-06.2, using a LSL of 91.0 (minimum of 91 percent of the maximum density). 36 The maximum density shall be determined by WSDOT FOP for AASHTO T 729. The 37 specified level of density attained will be determined by the evaluation of the density of I 38 39 the pavement. The density of the pavement shall be determined in accordance with WSDOT FOP for WAQTC TM 8, except that gauge correlation will be at the discretion of 40 the Engineer, when using the nuclear density gauge and WSDOT SOP 736 when using I 41 cores to determine density. 42 43 Tests for the determination of the pavement density will be taken in accordance with the I 44 required procedures for measurement by a nuclear density gauge or roadway cores after 45 completion of the finish rolling. 46 I 2023 FEDERAL OVERLAY FEDERAL AID#STBGUL-2715(011) I WO#3788 March 2,2023 SP-85
