CITY OF EVERETT SPECIAL PROVISIONS <br /> <br />Beverly Lake Water Quality Retrofit Division 5 – SURFACE TREATMENTS August 2023 <br /> <br />AND PAVEMENTS <br />WO No. – UP3745 SP - 172 <br />Thoroughly compact HMA for preleveling. Compact HMA used to <br />prelevel wheel ruts with a pneumatic tire roller unless Engineer <br />approves. <br />5-04.3(10)E2 HMA Compaction Nonstatistical Evaluation – <br />Acceptance Testing <br />Engineer will randomly select the location of the HMA compaction <br />acceptance tests from within each sublot, with one test per sublot. <br />5-04.3(10)E3 HMA Nonstatistical Compaction – Price <br />Adjustments <br />For each compaction lot with one or two sublots where all sublots <br />attain a relative density that is 92 percent of the reference maximum <br />density the HMA, City will accept at the unit Contract price with no <br />further evaluation. If a sublot does not attain a relative density that is <br />92 percent of the reference maximum density, the City will evaluate <br />the lot in accordance with Section 1-06.2 to determine the appropriate <br />CPF, with the maximum CPF being 1.00. However, lots with a <br />calculated CPF in excess of 1.00 will be used to offset lots with CPF <br />values below 1.00 but greater than 0.90. Lots with CPF lower than <br />0.90 will be evaluated for compliance per 5-04.3(11). Additional <br />testing by either a nuclear moisture-density gauge or cores will be <br />completed as required to provide a minimum of three tests for <br />evaluation. <br />For compaction below the required 92% a Non-Conforming <br />Compaction Factor (NCCF) will be determined. The NCCF equals the <br />algebraic difference of CPF minus 1.00 multiplied by 40 percent. The <br />Compaction Price Adjustment will be calculated as the product of <br />CPF, the quantity of HMA in the compaction control lot in tons, and the <br />unit Contract price per ton of mix. <br />5-04.3(11) Reject Work <br />5-04.3(11)A Reject Work General <br />City will reject defective or non-conforming Work. The Contractor may <br />propose, in writing, alternatives to removal and replacement of rejected <br />material. Engineer has sole discretion to determine acceptability of such <br />alternative proposals. Submit corrective action proposal for Engineer <br />approval for rejected HMA not conforming to the requirements in Section <br />1-06.2(2) and this specification. <br />5-04.3(11)B Rejection by Contractor <br />The Contractor may, prior to sampling, elect to remove any defective <br />material and replace it with new material. Any such new material will be <br />sampled, tested, and evaluated for acceptance. <br />5-04.3(11)C Rejection Without Testing (Mixture or Compaction) <br />The Engineer may, without sampling, reject any batch, load, or section of <br />Roadway that appears defective. Do NOT incorporate material rejected <br />before placement into the pavement. Remove any rejected section of <br />Roadway. <br />No payment will be made for the rejected materials or the removal of the <br />materials unless the Contractor requests testing of the rejected material. <br />If the Contractor elects to have the rejected material tested, obtain and
