CITY OF EVERETT SPECIAL PROVISIONS 1 <br /> nuclear density gauge and WSDOT SOP 736 when using cores to determine <br /> density. <br /> Tests for the determination of the pavement density will be taken in accordance 1 <br /> with the required procedures for measurement by a nuclear density gauge or <br /> 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 day <br /> the mix is placed and prior to opening to traffic. <br /> Roadway cores for density may be obtained by either the City or the Contractor I <br /> in accordance with WSDOT SOP 734. Provide minimum 4-inch core diameter, <br /> unless Engineer approves otherwise. The City will test Roadway cores in <br /> accordance with WSDOT FOP for AASHTO T 166. I <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 evaluation <br /> in accordance with instructions from the Engineer. Use the number of passes <br /> with an approved compaction train required to attain the maximum test point <br /> 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 not <br /> meet the minimum of 92 percent of the reference maximum density in a <br /> compaction lot with a CPF below 1.00 and thus subject to a price reduction <br /> 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 density <br /> gauge for the sublot and will be used for calculation of the CPF and <br /> 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. Provide <br /> traffic control in accordance with Engineer's direction. Failure by the <br /> Contractor to provide the requested traffic control will result in forfeiture of <br /> the request for cores. If the CPF for the lot based on the results of the <br /> HMA cores is less than 1.00, the City will deduct the cost for the coring <br /> from any monies due or that may become due the Contractor under the <br /> Contract at the rate of $200 per core. In addition, the cost of the traffic <br /> control will also be the Contractor's responsibility. <br /> Watermain Replacement"U" Division 5—SURFACE TREATMENTS October 1, 2019 <br /> AND PAVEMENTS <br /> WO No.—UP3698 SP- 158 1 <br />
