CITY OF EVERETT SPECIAL PROVISIONS <br /> <br />3rd Ave Water Quality Facility Division 5 – SURFACE TREATMENTS September 12, 2024 <br />AND PAVEMENTS <br />WO No. – UP 3775 SP - 158 <br />and speed change, and having a specified compacted course thickness <br />greater than 0.10-foot, to a specified level of relative density. The specified <br />level of relative density shall be a Composite Pay Factor (CPF) of not less <br />than 0.75 when evaluated in accordance with Section 1-06.2, using a LSL of <br />92.0 (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 <br />pavement; except, Engineer will have discretion regarding gauge correlation <br />using the nuclear density gauge and WSDOT SOP 736 when using cores to <br />determine density. <br />Tests for the determination of the pavement density will be taken in <br />accordance with the required procedures for measurement by a nuclear <br />density gauge or roadway cores after completion of the finish rolling. <br />If the City uses a nuclear density gauge to determine density, the City will use <br />the test procedures FOP for WAQTC TM 8 and WSDOT SOP T 729 on the <br />day the mix is placed and prior to opening to traffic. <br />Roadway cores for density may be obtained by either the City or the <br />Contractor in accordance with WSDOT SOP 734. Provide minimum 4-inch <br />core diameter, unless Engineer approves otherwise. The City will test <br />Roadway cores in accordance with WSDOT FOP for AASHTO T 166. <br />If the Contract includes the Bid item “Roadway Core”, obtain the cores in the <br />presence of the Engineer on the same day the mix is placed and at Engineer <br />designated locations. If the Contract does not include the Bid item “Roadway <br />Core”, then the City will obtain the cores. <br />For a lot in progress with a CPF less than 0.75, a new lot will begin at the <br />Contractor’s request after the Engineer is satisfied that material conforming to <br />the Specifications can be produced. <br />Compact HMA mixture accepted by commercial evaluation and HMA <br />constructed under conditions other than those listed above on the basis of a <br />test point evaluation of the compaction train. Perform the test point <br />evaluation in accordance with instructions from the Engineer. Use the <br />number of passes with an approved compaction train required to attain the <br />maximum test point density on all subsequent paving. <br />Thoroughly compact HMA for preleveling. Compact HMA used for preleveling <br />wheel rutting with a pneumatic tire roller unless Engineer approves otherwise. <br />5-04.3(10)A Test Results <br />For a sublot that has been tested with a nuclear density gauge that did <br />not meet the minimum of 92 percent of the reference maximum density in <br />a compaction lot with a CPF below 1.00 and thus subject to a price <br />reduction or rejection, the Contractor may request that a core be used for <br />determination of the relative density of the sublot. The relative density of <br />the core will replace the relative density determined by the nuclear <br />density gauge for the sublot and will be used for calculation of the CPF <br />and acceptance of HMA compaction lot. <br />When City takes cores at the Contractor’s request, the City must receive <br />request by noon of the next workday after the Contractor is provided with <br />nuclear density test results for the sublot. City will obtain core(s) from <br />locations outside of wheel paths and as the Engineer determines.
