Il I 2 5-04.3(10)D2 HMA Compaction Nonstatistical Evaluation—Acceptance Testing 3 The location of the HMA compaction acceptance tests will be randomly selected by the I 4 Engineer from within each sublot, with one test per sublot. 5 6 5-O4.3(10)D3 HMA Nonstatistical Compaction— Price Adjustments I 7 For each compaction lot with one or two sublots, having all sublots attain a relative density 8 that is 91 percent of the reference maximum density the HMA shall be accepted at the unit 9 Contract price with no further evaluation. When a sublot does not attain a relative density I 10 that is 91 percent of the reference maximum density, the lot shall be evaluated in 11 accordance with Section 1-06.2 to determine the appropriate CPF. The maximum CPF shall 12 be 1.00, however, lots with a calculated CPF in excess of 1.00 will be used to offset lots with I13 14 CPF values below 1.00 but greater than 0.90. Lots with CPF lower than 0.90 will be evaluated for compliance per 5-04.3(11). Additional testing by either a nuclear moisture- 15 density gauge or cores will be completed as required to provide a minimum of three tests for I 16 evaluation. 17 18 For compaction below the required 91% a Non-Conforming Compaction Factor(NCCF) will I 19 be determined. The NCCF equals the algebraic difference of CPF minus 1.00 multiplied by 20 40 percent. The Compaction Price Adjustment will be calculated as the product of CPF, the 21 quantity of HMA in the compaction control lot in tons, and the unit Contract price per ton of I 22 mix. 23 24 5-04.3(11) Reject Work I25 26 5-04.3(11)A Reject Work General 27 Work that is defective or does not conform to Contract requirements shall be rejected. The I28 Contractor may propose, in writing, alternatives to removal and replacement of rejected 29 material. Acceptability of such alternative proposals will be determined at the sole discretion 30 of the Engineer. HMA that has been rejected is subject to the requirements in Section 1- ' 31 06.2(2) and this specification, and the Contractor shall submit a corrective action proposal to 32 the Engineer for approval. 33 1 34 5-04.3(11)B Rejection by Contractor 35 The Contractor may, prior to sampling, elect to remove any defective material and replace it I 36 with new material. Any such new material will be sampled, tested, and evaluated for 37 acceptance. 38 I 39 5-04.3(11)C Rejection Without Testing (Mixture or Compaction) 40 The Engineer may, without sampling, reject any batch, load, or section of Roadway that 41 appears defective. Material rejected before placement shall not be incorporated into the I 42 pavement. Any rejected section of Roadway shall be removed. 43 44 No payment will be made for the rejected materials or the removal of the materials unless I 45 the Contractor requests that the rejected material be tested. If the Contractor elects to have 46 the rejected material tested, a minimum of three representative samples will be obtained 47 and tested. Acceptance of rejected material will be based on conformance with the I 48 nonstatistical acceptance Specification. If the CPF for the rejected material is less than 0.75, 49 no payment will be made for the rejected material; in addition, the cost of sampling and I 2020 PAVEMENT MAINTENANCE OVERLAY PAGE 59 OF 79 SPECIAL PROVISIONS WORK ORDER 3727 FEBRUARY 20,2020
