CITY OF EVERETT SPECIAL PROVISIONS <br /> <br />3rd Ave Water Quality Facility Division 5 – SURFACE TREATMENTS September 12, 2024 <br />AND PAVEMENTS <br />WO No. – UP 3775 SP - 160 <br />Compact HMA mixture accepted by commercial evaluation and HMA <br />constructed under conditions other than those listed above on the <br />basis of a test point evaluation of the compaction train. Perform the <br />test point evaluation in accordance with instructions from the <br />Engineer. Use the number of passes with an approved compaction <br />train required to attain the maximum test point density on all <br />subsequent paving. <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 <br />is 92 percent of the reference maximum density, the City will <br />evaluate the lot in accordance with Section 1-06.2 to determine the <br />appropriate CPF, with the maximum CPF being 1.00. However, lots <br />with a calculated CPF in excess of 1.00 will be used to offset lots <br />with CPF values below 1.00 but greater than 0.90. Lots with CPF <br />lower than 0.90 will be evaluated for compliance per 5-04.3(11). <br />Additional testing by either a nuclear moisture-density gauge or <br />cores will be completed as required to provide a minimum of three <br />tests for evaluation. <br />For compaction below the required 92% a Non-Conforming <br />Compaction Factor (NCCF) will be determined. The NCCF equals <br />the algebraic difference of CPF minus 1.00 multiplied by 40 percent. <br />The Compaction Price Adjustment will be calculated as the product <br />of CPF, the quantity of HMA in the compaction control lot in tons, and <br />the 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.
