I <br /> 1 If the Contract includes the Bid item "Roadway Core" the cores shall be obtained by the I <br /> 2 Contractor in the presence of the Engineer on the same day the mix is placed and at <br /> 3 locations designated by the Engineer. If the Contract does not include the Bid item <br /> 4 "Roadway Core" the Contracting Agency will obtain the cores. <br /> 5 <br /> 6 For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractor's <br /> 7 request after the Engineer is satisfied that material conforming to the Specifications can <br /> 8 be produced. <br /> 9 <br /> 10 HMA mixture accepted by commercial evaluation and HMA constructed under conditions <br /> 11 other than those listed above shall be compacted on the basis of a test point evaluation <br /> 12 of the compaction train. The test point evaluation shall be performed in accordance with <br /> 13 instructions from the Engineer. The number of passes with an approved compaction <br /> 14 train, required to attain the maximum test point density, shall be used on all subsequent <br /> 15 paving. <br /> 16 <br /> 17 HMA for preleveling shall be thoroughly compacted. HMA that is used for preleveling <br /> 18 wheel rutting shall be compacted with a pneumatic tire roller unless otherwise approved <br /> 19 by the Engineer. <br /> 20 <br /> 21 Test Results I <br /> 22 For a sublot that has been tested with a nuclear density gauge that did not meet the <br /> 23 minimum of 92 percent of the reference maximum density in a compaction lot with a <br /> 24 CPF below 1.00 and thus subject to a price reduction or rejection, the Contractor may <br /> 25 request that a core be used for determination of the relative density of the sublot. The <br /> 26 relative density of the core will replace the relative density determined by the nuclear <br /> 27 density gauge for the sublot and will be used for calculation of the CPF and acceptance I <br /> 28 of HMA compaction lot. <br /> 29 <br /> 30 When cores are taken by the Contracting Agency at the request of the Contractor, they I <br /> 31 shall be requested by noon of the next workday after the test results for the sublot have <br /> 32 been provided or made available to the Contractor. Core locations shall be outside of <br /> 33 wheel paths and as determined by the Engineer. Traffic control shall be provided by the <br /> 34 Contractor as requested by the Engineer. Failure by the Contractor to provide the <br /> 35 requested traffic control will result in forfeiture of the request for cores. When the CPF for <br /> 36 the lot based on the results of the HMA cores is less than 1.00, the cost for the coring <br /> 37 will be deducted from any monies due or that may become due the Contractor under the <br /> 38 Contract at the rate of$200 per core and the Contractor shall pay for the cost of the <br /> 39 traffic control. <br /> 40 <br /> 41 5-04.3(10)A HMA Compaction — General Compaction Requirements <br /> 42 Compaction shall take place when the mixture is in the proper condition so that no I <br /> 43 undue displacement, cracking, or shoving occurs. Areas inaccessible to large <br /> 44 compaction equipment shall be compacted by other mechanical means. Any HMA that <br /> 45 becomes loose, broken, contaminated, shows an excess or deficiency of asphalt, or is in <br /> I <br /> 46 any way defective, shall be removed and replaced with new hot mix that shall be <br /> 47 immediately compacted to conform to the surrounding area. <br /> 1 <br /> N.
