18TH STREET PEDESTRIAN IMPROVEMENTS 3741 RMT July 03, 2024 55 1 5-04.3(10)C Vacant 2 3 5-04.3(10)D HMA Nonstatistical Compaction 4 5 5-04.3(10)D1 HMA Nonstatistical Compaction – Lots and Sublots 6 HMA compaction which is accepted by nonstatistical evaluation will be based on 7 acceptance testing performed by the Contracting Agency dividing the project into 8 compaction lots. 9 10 A lot is represented by randomly selected samples of the same mix design that will be 11 tested for acceptance. A lot is defined as the total quantity of material or work produced 12 for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be 13 equal to one day’s production or 400 tons, whichever is less except that the final sublot 14 will be a minimum of 200 tons and may be increased to 800 tons. Testing for compaction 15 will be at the rate of 5 tests per sublot per WSDOT T 738. 16 17 The sublot locations within each density lot will be determined by the Engineer. For a lot 18 in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request 19 after the Engineer is satisfied that material conforming to the Specifications can be 20 produced. 21 22 HMA mixture accepted by commercial evaluation and HMA constructed under conditions 23 other than those listed above shall be compacted on the basis of a test point evaluation 24 of the compaction train. The test point evaluation shall be performed in accordance with 25 instructions from the Engineer. The number of passes with an approved compaction 26 train, required to attain the maximum test point density, shall be used on all subsequent 27 paving. 28 29 HMA for preleveling shall be thoroughly compacted. HMA that is used to prelevel wheel 30 ruts shall be compacted with a pneumatic tire roller unless otherwise approved by the 31 Engineer. 32 33 5-04.3(10)D2 HMA Compaction Nonstatistical Evaluation – Acceptance Testing 34 The location of the HMA compaction acceptance tests will be randomly selected by the 35 Engineer from within each sublot, with one test per sublot. 36 37 5-04.3(10)D3 HMA Nonstatistical Compaction – Price Adjustments 38 For each compaction lot with one or two sublots, having all sublots attain a relative 39 density that is 91 percent of the reference maximum density the HMA shall be accepted 40 at the unit Contract price with no further evaluation. When a sublot does not attain a 41 relative density that is 91 percent of the reference maximum density, the lot shall be 42 evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The 43 maximum CPF shall be 1.00, however, lots with a calculated CPF in excess of 1.00 will 44 be used to offset lots with CPF values below 1.00 but greater than 0.90. Lots with CPF 45 lower than 0.90 will be evaluated for compliance per 5-04.3(11). Additional testing by 46
