Edgewater Creek Bridge Replacement November 2023 113 1 5-04.3(10)D HMA Nonstatistical Compaction 2 3 5-04.3(10)D1 HMA Nonstatistical Compaction – Lots and Sublots 4 HMA compaction which is accepted by nonstatistical evaluation will be based on 5 acceptance testing performed by the Contracting Agency dividing the project into 6 compaction lots. 7 8 A lot is represented by randomly selected samples of the same mix design that will be 9 tested for acceptance. A lot is defined as the total quantity of material or work produced 10 for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be 11 equal to one day’s production or 400 tons, whichever is less except that the final sublot 12 will be a minimum of 200 tons and may be increased to 800 tons. Testing for compaction 13 will be at the rate of 5 tests per sublot per WSDOT T 738. 14 15 The sublot locations within each density lot will be determined by the Engineer. For a lot 16 in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request 17 after the Engineer is satisfied that material conforming to the Specifications can be 18 produced. 19 20 HMA mixture accepted by commercial evaluation and HMA constructed under conditions 21 other than those listed above shall be compacted on the basis of a test point evaluation 22 of the compaction train. The test point evaluation shall be performed in accordance with 23 instructions from the Engineer. The number of passes with an approved compaction 24 train, required to attain the maximum test point density, shall be used on all subsequent 25 paving. 26 27 HMA for preleveling shall be thoroughly compacted. HMA that is used to prelevel wheel 28 ruts shall be compacted with a pneumatic tire roller unless otherwise approved by the 29 Engineer. 30 31 5-04.3(10)D2 HMA Compaction Nonstatistical Evaluation – Acceptance Testing 32 The location of the HMA compaction acceptance tests will be randomly selected by the 33 Engineer from within each sublot, with one test per sublot. 34 35 5-04.3(10)D3 HMA Nonstatistical Compaction – Price Adjustments 36 For each compaction lot with one or two sublots, having all sublots attain a relative 37 density that is 92 percent of the reference maximum density the HMA shall be accepted 38 at the unit Contract price with no further evaluation. When a sublot does not attain a 39 relative density that is 92 percent of the reference maximum density, the lot shall be 40 evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The 41 maximum CPF shall be 1.00, however, lots with a calculated CPF in excess of 1.00 will 42 be used to offset lots with CPF values below 1.00 but greater than 0.90. Lots with CPF 43 lower than 0.90 will be evaluated for compliance per 5-04.3(11). Additional testing by 44 either a nuclear moisture-density gauge or cores will be completed as required to provide 45 a minimum of three tests for evaluation. 46 47
