2025 PAVEMENT MAINTENANCE OVERLAY SPECIAL PROVISIONS <br />PW# 3830 <br /> SP-61 March 26, 2025 <br /> <br />HMA for preleveling shall be thoroughly compacted. HMA that is used to prelevel wheel 1 <br />ruts shall be compacted with a pneumatic tire roller unless otherwise approved by the 2 <br />Engineer. 3 <br /> 4 <br />5-04.3(10)D2 HMA Compaction Nonstatistical Evaluation – Acceptance Testing 5 <br />The location of the HMA compaction acceptance tests will be randomly selected by the 6 <br />Engineer from within each sublot, with one test per sublot. 7 <br /> 8 <br />5-04.3(10)D3 HMA Nonstatistical Compaction – Price Adjustments 9 <br />For each compaction lot with one or two sublots, having all sublots attain a relative 10 <br />density that is 92 percent of the reference maximum density the HMA shall be accepted 11 <br />at the unit Contract price with no further evaluation. When a sublot does not attain a 12 <br />relative density that is 92 percent of the reference maximum density, the lot shall be 13 <br />evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The 14 <br />maximum CPF shall be 1.00, however, lots with a calculated CPF in excess of 1.00 will 15 <br />be used to offset lots with CPF values below 1.00 but greater than 0.90. Lots with CPF 16 <br />lower than 0.90 will be evaluated for compliance per 5-04.3(11). Additional testing by 17 <br />either a nuclear moisture-density gauge or cores will be completed as required to provide 18 <br />a minimum of three tests for evaluation. 19 <br /> 20 <br />For compaction below the required 92%, a Non-Conforming Compaction Factor (NCCF) 21 <br />will be determined. The NCCF equals the algebraic difference of CPF minus 1.00 22 <br />multiplied by 40 percent. The Compaction Price Adjustment will be calculated as the 23 <br />product of CPF, the quantity of HMA in the compaction control lot in tons, and the unit 24 <br />Contract price per ton of mix. 25 <br /> 26 <br />5-04.3(11) Reject Work 27 <br /> 28 <br />5-04.3(11)A Reject Work General 29 <br />Work that is defective or does not conform to Contract requirements shall be rejected. 30 <br />The Contractor may propose, in writing, alternatives to removal and replacement of 31 <br />rejected material. Acceptability of such alternative proposals will be determined at the 32 <br />sole discretion of the Engineer. HMA that has been rejected is subject to the 33 <br />requirements in Section 1-06.2(2) and this specification, and the Contractor shall submit 34 <br />a corrective action proposal to the Engineer for approval. 35 <br /> 36 <br />5-04.3(11)B Rejection by Contractor 37 <br />The Contractor may, prior to sampling, elect to remove any defective material and 38 <br />replace it with new material. Any such new material will be sampled, tested, and 39 <br />evaluated for acceptance. 40 <br /> 41 <br />5-04.3(11)C Rejection Without Testing (Mixture or Compaction) 42 <br />The Engineer may, without sampling, reject any batch, load, or section of Roadway that 43 <br />appears defective. Material rejected before placement shall not be incorporated into the 44 <br />pavement. Any rejected section of Roadway shall be removed. 45 <br /> 46
