I I1 2 The type of rollers to be used and their relative position in the compaction sequence I 3 shall generally be the Contractor's option, provided the specified densities are attained. 4 Unless the Engineer has approved otherwise, rollers shall only be operated in the static 5 mode when the internal temperature of the mix is less than 175°F. Regardless of mix 6 temperature, a roller shall not be operated in a mode that results in checking or cracking I 7 of the mat. Rollers shall only be operated in static mode on bridge decks. 8 I 9 10 5-04.3(10)B HMA Compaction — Cyclic Density Low cyclic density areas are defined as spots or streaks in the pavement that are less 11 than 90 percent of the theoretical maximum density. At the Engineer's discretion, the 12 Engineer may evaluate the HMA pavement for low cyclic density, and when doing so will 13 follow WSDOT SOP 733. A $500 Cyclic Density Price Adjustment will be assessed for 14 any 500-foot section with two or more density readings below 90 percent of the I 15 theoretical maximum density. 16 17 5-04.3(10)C Vacant I 18 19 5-04.3(10)D HMA Nonstatistical Compaction 20 I21 5-04.3(10)D1 HMA Nonstatistical Compaction — Lots and Sublots 22 HMA compaction which is accepted by nonstatistical evaluation will be based on I 23 acceptance testing performed by the Contracting Agency dividing the project into 24 compaction lots. 25 I 26 A lot is represented by randomly selected samples of the same mix design that will be 27 tested for acceptance. A lot is defined as the total quantity of material or work produced 28 for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be I 29 equal to one day's production or 400 tons, whichever is less except that the final sublot 30 will be a minimum of 200 tons and may be increased to 800 tons. Testing for compaction 31 will be at the rate of 5 tests per sublot per WSDOT T 738. I 32 33 The sublot locations within each density lot will be determined by the Engineer. For a lot 34 in progress with a CPF less than 0.75, a new lot will begin at the Contractor's request I 35 after the Engineer is satisfied that material conforming to the Specifications can be 36 produced. 37 I 38 HMA mixture accepted by commercial evaluation and HMA constructed under conditions 39 other than those listed above shall be compacted on the basis of a test point evaluation 40 of the compaction train. The test point evaluation shall be performed in accordance with I 41 instructions from the Engineer. The number of passes with an approved compaction 42 train, required to attain the maximum test point density, shall be used on all subsequent 43 paving. 1 44 I N.
