2024 Pavement Maintenance Overlay SPECIAL PROVISIONS PW# 3823 57 “f” All aggregate passing: 1½″, 1″, ¾″, ½″, ⅜″ and No.4 sieves 2 All aggregate passing No. 8 sieve 15 All aggregate passing No. 200 sieve 20 Asphalt binder 40 Air Voids (Va) (where applicable) 20 1 Each lot of HMA produced under Nonstatistical Evaluation and having all constituents 2 falling within the tolerance limits of the job mix formula shall be accepted at the unit 3 Contract price with no further evaluation. When one or more constituents fall outside the 4 nonstatistical tolerance limits in the Job Mix Formula shown in Table of Price Adjustment 5 Factors, the lot shall be evaluated in accordance with Section 1-06.2 to determine the 6 appropriate CPF. The nonstatistical tolerance limits will be used in the calculation of the 7 CPF and the maximum CPF shall be 1.00. When less than three sublots exist, backup 8 samples of the existing sublots or samples from the Roadway shall be tested to provide 9 a minimum of three sets of results for evaluation. 10 11 5-04.3(9)C5 Vacant 12 13 5-04.3(9)C6 Mixture Nonstatistical Evaluation – Price Adjustments 14 For each lot of HMA mix produced under Nonstatistical Evaluation when the calculated 15 CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. The 16 NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 60 percent. The 17 total job mix compliance price adjustment will be calculated as the product of the NCMF, 18 the quantity of HMA in the lot in tons, and the unit Contract price per ton of mix. 19 20 If a constituent is not measured in accordance with these Specifications, its individual 21 pay factor will be considered 1.00 in calculating the Composite Pay Factor (CPF). 22 23 5-04.3(9)C7 Mixture Nonstatistical Evaluation - Retests 24 The Contractor may request a sublot be retested. To request a retest, the Contractor 25 shall submit a written request within 7 calendar days after the specific test results have 26 been received. A split of the original acceptance sample will be retested. The split of the 27 sample will not be tested with the same tester that ran the original acceptance test. The 28 sample will be tested for a complete gradation analysis, asphalt binder content, and, at 29 the option of the agency, Va. The results of the retest will be used for the acceptance of 30 the HMA in place of the original sublot sample test results. The cost of testing will be 31 deducted from any monies due or that may come due the Contractor under the Contract 32 at the rate of $500 per sample. 33 34 5-04.3(9)D Mixture Acceptance – Commercial Evaluation 35 If sampled and tested, HMA produced under Commercial Evaluation and having all 36 constituents falling within the tolerance limits of the job mix formula shall be accepted at 37 the unit Contract price with no further evaluation. When one or more constituents fall 38 outside the commercial tolerance limits in the Job Mix Formula shown in 5-04.3(9), the 39
