I 1 HMA mixture accepted by commercial evaluation and HMA constructed under conditions 2 other than those listed above shall be compacted on the basis of a test point evaluation ' 3 of the compaction train. The test point evaluation shall be performed in accordance with 4 instructions from the Engineer. The number of passes with an approved compaction 5 train, required to attain the maximum test point density, shall be used on all subsequent 6 paving. 7 8 HMA for preleveling shall be thoroughly compacted. HMA that is used to prelevel wheel , 9 ruts shall be compacted with a pneumatic tire roller unless otherwise approved by the 10 Engineer. 11 I 12 5-04.3(10)D2 HMA Compaction Nonstatistical Evaluation —Acceptance Testing 13 The location of the HMA compaction acceptance tests will be randomly selected by the I 14 Engineer from within each sublot, with one test per sublot. 15 16 5-04.3(10)D3 HMA Nonstatistical Compaction — Price Adjustments I 17 For each compaction lot with one or two sublots, having all sublots attain a relative 18 density that is 91 percent of the reference maximum density the HMA shall be accepted 19 at the unit Contract price with no further evaluation. When a sublot does not attain a I 20 relative density that is 91 percent of the reference maximum density, the lot shall be 21 evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The 22 maximum CPF shall be 1.00, however, lots with a calculated CPF in excess of 1.00 will I 23 be used to offset lots with CPF values below 1.00 but greater than 0.90. Lots with CPF 24 lower than 0.90 will be evaluated for compliance per 5-04.3(11). Additional testing by 25 either a nuclear moisture-density gauge or cores will be completed as required to provide I 26 a minimum of three tests for evaluation. 27 28 For compaction below the required 91% a Non-Conforming Compaction Factor (NCCF) I 29 will be determined. The NCCF equals the algebraic difference of CPF minus 1.00 30 multiplied by 40 percent. The Compaction Price Adjustment will be calculated as the 31 product of CPF, the quantity of HMA in the compaction control lot in tons, and the unit 32 Contract price per ton of mix. 33 34 5-04.3(11) Reject Work I 35 36 5-O4.3(11)A Reject Work General 37 Work that is defective or does not conform to Contract requirements shall be rejected. I 38 The Contractor may propose, in writing, alternatives to removal and replacement of 39 rejected material. Acceptability of such alternative proposals will be determined at the 40 sole discretion of the Engineer. HMA that has been rejected is subject to the I 41 requirements in Section 1-06.2(2) and this specification, and the Contractor shall submit 42 a corrective action proposal to the Engineer for approval. 43 I 44 5-O4.3(11)B Rejection by Contractor 45 The Contractor may, prior to sampling, elect to remove any defective material and 46 replace it with new material. Any such new material will be sampled, tested, and 1 47 evaluated for acceptance. I 2023 FEDERAL OVERLAY FEDERAL AID#STBGUL-2715(011) I WO#3788 March 2,2023 SP-88
