Fulton Street Pedestrian Bicycle Corridor PAGE 91 OF 114 CONTRACT FEDERAL AID # TAP-0420(026) WO #3785 September 6, 2024 1 5-04.3(10)B HMA Compaction – Cyclic Density 2 Low cyclic density areas are defined as spots or streaks in the pavement that are less 3 than 90 percent of the theoretical maximum density. At the Engineer’s discretion, the 4 Engineer may evaluate the HMA pavement for low cyclic density, and when doing so will 5 follow WSDOT SOP 733. A $500 Cyclic Density Price Adjustment will be assessed for 6 any 500-foot section with two or more density readings below 90 percent of the 7 theoretical maximum density. 8 9 5-04.3(10)C Vacant 10 11 5-04.3(10)D HMA Nonstatistical Compaction 12 13 5-04.3(10)D1 HMA Nonstatistical Compaction – Lots and Sublots 14 HMA compaction which is accepted by nonstatistical evaluation will be based on 15 acceptance testing performed by the Contracting Agency dividing the project into 16 compaction lots. 17 18 A lot is represented by randomly selected samples of the same mix design that will be 19 tested for acceptance. A lot is defined as the total quantity of material or work produced 20 for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be 21 equal to one day’s production or 400 tons, whichever is less except that the final sublot 22 will be a minimum of 200 tons and may be increased to 800 tons. Testing for compaction 23 will be at the rate of 5 tests per sublot per WSDOT T 738. 24 25 The sublot locations within each density lot will be determined by the Engineer. For a lot 26 in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request 27 after the Engineer is satisfied that material conforming to the Specifications can be 28 produced. 29 30 HMA mixture accepted by commercial evaluation and HMA constructed under conditions 31 other than those listed above shall be compacted on the basis of a test point evaluation 32 of the compaction train. The test point evaluation shall be performed in accordance with 33 instructions from the Engineer. The number of passes with an approved compaction 34 train, required to attain the maximum test point density, shall be used on all subsequent 35 paving. 36 37 HMA for preleveling shall be thoroughly compacted. HMA that is used to prelevel wheel 38 ruts shall be compacted with a pneumatic tire roller unless otherwise approved by the 39 Engineer. 40 41 5-04.3(10)D2 HMA Compaction Nonstatistical Evaluation – Acceptance Testing 42 The location of the HMA compaction acceptance tests will be randomly selected by the 43 Engineer from within each sublot, with one test per sublot. 44 45 5-04.3(10)D3 HMA Nonstatistical Compaction – Price Adjustments 46
