CITY OF EVERETT SPECIAL PROVISIONS <br /> <br />Beverly Lake Water Quality Retrofit Division 5 – SURFACE TREATMENTS August 2023 <br /> <br />AND PAVEMENTS <br />WO No. – UP3745 SP - 169 <br />of material or work produced for each Job Mix Formula placed. Only one <br />lot per JMF is expected. A sublot will be equal to one day’s production or <br />800 tons, whichever is less; except, the final sublot will be a minimum of <br />400 tons and may be increased to 1200 tons. <br />Collectively evaluate all test results obtained from the acceptance <br />samples from a given lot. If the Contractor requests a change to the JMF <br />that is approved, the material produced after the change will be <br />evaluated on the basis of the new JMF for the remaining sublots in the <br />current lot and for acceptance of subsequent lots. For a lot in progress <br />with a CPF less than 0.75, a new lot will begin at the Contractor’s request <br />after the Engineer is satisfied that material conforming to the <br />Specifications can be produced. <br />Perform sampling and testing for evaluation on the frequency of one <br />sample per sublot. <br />5-04.3(9)C2 Mixture Nonstatistical Evaluation Sampling <br />Obtain samples for acceptance testing when ordered by the Engineer. <br />Sample the HMA mixture in the presence of the Engineer and in <br />accordance with AASH-TO T 168. Take a minimum of three samples for <br />each class of HMA placed on a project. If used in a structural application, <br />test at least one of the three samples taken. <br />Sampling and testing HMA in a Structural application where quantities <br />are less than 400 tons is at the Engineer’s discretion. <br />For HMA used in a structural application and with a total project quantity <br />less than 800 tons but more than 400 tons, preform a minimum of one <br />acceptance test. In all cases, obtain a minimum of three samples at the <br />point of acceptance. Test a minimum of one of the three samples for <br />conformance to the JMF: <br />a. If the test results are found to be within specification requirements, <br />additional testing will be at the Engineer’s discretion. <br />5-04.3(9)C3 Mixture Nonstatistical Evaluation – Acceptance Testing <br />Testing of HMA for compliance of Va will be the City’s option. If tested, <br />compliance of Va will use WSDOT SOP 731. <br />Testing for compliance of asphalt binder content will be by WSDOT FOP <br />for AASHTO T 308. <br />Testing for compliance of gradation will be by FOP for WAQTC T 27/T 11. <br />5-04.3(10) HMA Compaction Acceptance <br />Compact HMA mixture accepted by nonstatistical evaluation being used in <br />traffic lanes; including lanes for intersections, ramps, truck climbing, weaving, <br />and speed change, and having a specified compacted course thickness greater <br />than 0.10-foot, to a specified level of relative density. The specified level of <br />relative density shall be a Composite Pay Factor (CPF) of not less than 0.75 <br />when evaluated in accordance with Section 1-06.2, using a LSL of 92.0 <br />(minimum of 92 percent of the maximum density). Use WSDOT FOP for <br />AASHTO T 729 to determine maximum density. The specified level of density <br />attained will be determined by the evaluation of the density of the pavement. <br />Use WSDOT FOP for WAQTC TM 8 to determine the density of the pavement; <br />except, Engineer will have discretion regarding gauge correlation using the
