CITY OF EVERETT WEST MARINE VIEW DRIVE/ALVERSON AND 41 ST ST/GRAND AVE <br />PEDESTRIAN IMPROVEMENTS <br />STATE FUND# HLP-PB15(032) <br />WO #3630 July 25, 2024 <br />71 <br />1 <br />2 5-04.3(9)D Mixture Acceptance Commercial Evaluation <br />3 If sampled and tested, HMA produced under Commercial Evaluation and having all <br />4 constituents falling within the tolerance limits of the job mix formula shall be accepted at <br />5 the unit Contract price with no further evaluation. When one or more constituents fall <br />6 outside the commercial tolerance limits in the Job Mix Formula shown in 5-04.3(9), the lot <br />7 shall be evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. <br />8 The commercial tolerance limits will be used in the calculation of the CPF and the <br />9 maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the <br />10 existing sublots or samples from the street shall be tested to provide a minimum of three <br />11 sets of results for evaluation. <br />12 <br />13 For each lot of HMA mix produced and tested under Commercial Evaluation when the <br />14 calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be <br />15 determined. The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by <br />16 60 percent. The Job Mix Compliance Price Adjustment will be calculated as the product of <br />17 the NCMF, the quantity of HMA in the lot in tons, and the unit Contract price per ton of <br />18 mix. <br />19 <br />20 If a constituent is not measured in accordance with these Specifications, 4+5X43<4B4<%9& pay <br />21 factor will be considered 1.00 in calculating the Composite 9'X98+1*X") <br />22 <br />23 5-04.3(10) HMA Compaction Acceptance <br />24 HMA mixture accepted by nonstatistical evaluation that is used in traffic lanes, including <br />25 lanes for intersections, ramps, truck climbing, weaving, and speed change, and having a <br />26 specified compacted course thickness greater than 0.10-foot, shall be compacted to a <br />27 specified level of relative density. The specified level of relative density shall be a <br />28 Composite Pay Factor (CPF) of not less than 0.75 when evaluated in accordance with <br />29 Section 1-06.2, using a LSL of 91.0 (minimum of 91 percent of the maximum density). <br />30 The maximum density shall be determined by WSDOT FOP for AASHTO T 729. The <br />31 specified level of density attained will be determined by the evaluation of the density of <br />32 the pavement. The density of the pavement shall be determined in accordance with <br />33 WSDOT FOP for WAQTC TM 8, except that gauge correlation will be at the discretion of <br />34 the Engineer, when using the nuclear density gauge and WSDOT SOP 736 when using <br />35 cores to determine density. <br />36 <br />37 Tests for the determination of the pavement density will be taken in accordance with the <br />38 required procedures for measurement by a nuclear density gauge or roadway cores after <br />39 completion of the finish rolling. <br />40 <br />41 If the Contracting Agency uses a nuclear density gauge to determine density the test <br />42 procedures FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day the <br />43 mix is placed and prior to opening to traffic. <br />44 <br />45 Roadway cores for density may be obtained by either the Contracting Agency or the <br />46 Contractor in accordance with WSDOT SOP 734. The core diameter shall be 4-inches <br />47 minimum, unless otherwise approved by the Engineer. Roadway cores will be tested by <br />48 the Contracting Agency in accordance with WSDOT FOP for AASHTO T 166.
