I I 2 If the Contracting Agency uses a nuclear density gauge to determine density the test 3 procedures FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day the mix I 4 is placed and prior to opening to traffic. 5 6 Roadway cores for density may be obtained by either the Contracting Agency or the I 7 8 Contractor in accordance with WSDOT SOP 734. The core diameter shall be 4-inches minimum, unless otherwise approved by the Engineer. Roadway cores will be tested by the 9 Contracting Agency in accordance with WSDOT FOP for AASHTO T 166. I 10 11 If the Contract includes the Bid item "Roadway Core" the cores shall be obtained by the 12 Contractor in the presence of the Engineer on the same day the mix is placed and at 13 locations designated by the Engineer. If the Contract does not include the Bid item 14 "Roadway Core" the Contracting Agency will obtain the cores. 15 I 16 For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractor's 17 request after the Engineer is satisfied that material conforming to the Specifications can be 18 produced. I 19 20 HMA mixture accepted by commercial evaluation and HMA constructed under conditions 21 other than those listed above shall be compacted on the basis of a test point evaluation of I 22 the compaction train. The test point evaluation shall be performed in accordance with 23 instructions from the Engineer. The number of passes with an approved compaction train, 24 required to attain the maximum test point density, shall be used on all subsequent paving. I25 26 HMA for preleveling shall be thoroughly compacted. HMA that is used for preleveling wheel 27 rutting shall be compacted with a pneumatic tire roller unless otherwise approved by the 1 28 Engineer. 29 I 30 Test Results 31 For a sublot that has been tested with a nuclear density gauge that did not meet the 32 minimum of 91 percent of the reference maximum density in a compaction lot with a CPF ' 33 34 below 1.00 and thus subject to a price reduction or rejection, the Contractor may request that a core be used for determination of the relative density of the sublot. The relative 35 density of the core will replace the relative density determined by the nuclear density gauge 36 for the sublot and will be used for calculation of the CPF and acceptance of HMA 37 compaction lot. 38 I 39 When cores are taken by the Contracting Agency at the request of the Contractor, they shall 40 be requested by noon of the next workday after the test results for the sublot have been 41 provided or made available to the Contractor. Core locations shall be outside of wheel paths I 42 and as determined by the Engineer. Traffic control shall be provided by the Contractor as 43 requested by the Engineer. Failure by the Contractor to provide the requested traffic control 44 will result in forfeiture of the request for cores. When the CPF for the lot based on the results 45 of the HMA cores is less than 1.00, the cost for the coring will be deducted from any monies I 46 due or that may become due the Contractor under the Contract at the rate of$200 per core 47 and the Contractor shall pay for the cost of the traffic control. 1 48 49 5-04.3(10)A HMA Compaction —General Compaction Requirements I 2020 PAVEMENT MAINTENANCE OVERLAY PAGE 57 OF 79 SPECIAL PROVISIONS WORK ORDER 3727 FEBRUARY 20,2020
