CITY OF EVERETT SPECIAL PROVISIONS <br /> Compaction HMA <br /> 5-04.3(10)B <br /> — <br /> General Compaction Requirements <br /> Compact mixture only when the mixture is in the proper condition so that <br /> no undue displacement, cracking, or shoving occurs. Compact areas <br /> inaccessible to large compaction equipment by other mechanical means. <br /> Remove and replace HMA that becomes loose, broken, contaminated, <br /> shows excess or deficiency of asphalt, or is in any way defective, with new <br /> hot mix. Immediately compact to conform to the surrounding area. <br /> Provide type of rollers and their relative position in the compaction <br /> 1 sequence to attain the specified densities. Operate rollers shall only in the <br /> static mode when the internal temperature of the mix is less than 175°F <br /> unless Engineer approves otherwise. Do NOT operate a roller, regardless <br /> of mix temperature, in a mode that results in checking or cracking of the <br /> mat. Only operate rollers in static mode on bridge decks. <br /> 5-04.3(10)C HMA Compaction —Cyclic Density <br /> ' Low cyclic density areas are defined as spots or streaks in the pavement <br /> that are less than 90 percent of the theoretical maximum density. At the <br /> Engineer's discretion, the Engineer may evaluate the HMA pavement for <br /> low cyclic density and when doing so will follow WSDOT SOP 733. A$500 <br /> Cyclic Density Price Adjustment will be assessed for any 500-foot section <br /> with two or more density readings below 90 percent of the theoretical <br /> maximum density. <br /> 5-04.3(10)D Vacant <br /> 5-04.3(10)E HMA Nonstatistical Compaction <br /> 5-04.3(10)E1 HMA Nonstatistical Compaction — Lots and <br /> Sublots <br /> City will perform acceptance testing on HMA compaction that is <br /> accepted by nonstatistical evaluation by dividing the project into <br /> compaction lots. <br /> A lot is represented by randomly selected samples of the same mix <br /> design that will be tested for acceptance. A lot is defined as the total <br /> quantity of material or work produced for each Job Mix Formula <br /> placed. Only one lot per JMF is expected. A sublot is equal to one <br /> day's production or 400 tons, whichever is less, except; the final sublot <br /> will be a minimum of 200 tons and may be increased to 800 tons. <br /> Testing for compaction will be at the rate of 5 tests per sublot per <br /> WSDOT T 738. <br /> Engineer will determine the sublot locations within each density lot. <br /> For a lot in progress with a CPF less than 0.75, Contractor may <br /> request a new lot begin after the Engineer is satisfied that material <br /> conforming to the Specifications can be produced. <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 /> 1 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 /> Watermain Replacement"U" Division 5—SURFACE TREATMENTS October 1, 2019 <br /> AND PAVEMENTS <br /> WO No.—UP3698 SP-159 <br />
