�� PORT OF EVERETT W MARINE VIEW DR IMPROVEMENTS CIP N0. 3A-003-09 PROJECTNO. PD•WM-20006-01 accordance with Section 1-06.2(1), using a minimum of 91.0 percent of the reference maximum density as detertnined by WSDOT FOP for AASHTO T 209. The re(erence maximum density shall be determined as the moving average of the most recent five determinations for the lot of HMA being placed. The specified level of density attained will be detertnined by the statistical evaluation of five nuclear density gauge tests taken in accordance with WAQTC FOP TM 8 and WSDOT SOP T 729 on the day the HMA is placed (after completion of the finish rollina) at locations detertnined by ihe stratified random sampling procedure conforming to WSDOT Test Method 716 within each density lot. The quantity represented by each densily lot will be no grealer than a single day's production or 400 tons, whichever is less. The final lot tor each day of paving may be increased to 600 tons. The Engineer will fumish the Contractor with a copy of the results of all acceptance testing performed wilhin one working day. Acceptance of pavement compaction will be based on the statistical evaluation and CPF so determined. For compaction lols talling below a 1.00 pay factor and thus subject to price reducGon or rejection, cores may be used as an altemate to the nuclear density gauge tests. When cores are taken by the Cont2cGng Agency at the request of the Contractor, they shall be requested by noon of the next workday after paving. The cost for the coring expenses when the core results indicate the specified level oF relative density within a lot has not been achieved, will be deducted from any monies due or that may become due the Contractor under the contract at the rate of $125 percore. • At the start of paving, the Contractor must demonstrate to the Engineer that the HMA is compactable by constructing compaction test section(s). Test section(s) shail be constructed using the compaction train and a variety of rolling pattems that the Contractor expects to use in the paving operation. A test section will be considered to have established compatibility, based on the results of three densiry detertninations, when the average of the three tests exceeds 92 percent of Rice or when all three tests individually exceed 91 percent of Rice. This will require consideration of the presence of a coRelation factor tor the nuclear gauge and may require final resolution after the factor for the gauge is known. A minimum 1.00 compaction pay factor shall be used until a gauge correlation factor is known, and until the HMA is considered compactable. When construction of the lest section(s) has demonstrated that the HMA is not compactable, paving must stop. To resume paving, all factors contributing to compaction shall be analyzed and Engineer aaproved changes made, which may require a new mix design. When paving is resumed, lhe Contractor must again, as previously defined, demonstrate that the HMA is compactable. If the Contractor does not construct test section(s), the HMA is considered compactable and all HMA placed will be evaluated according to Section 5-04.3(10)B. HMA Class A, B, E, F, and G constructed under conditions other than listed above shall be compacted on the basis of a test point evaluation of the compaction train. The test point evaluation shall be performed in accordance with instructions from the Engineer. The number of passes with an approved compaction train, required to attain the maximum test point density, shall be used on all subsequent paving. HMA Class D and preleveling HMA shall be compacted to the satisiaction of the Engineer. in addilion to the randomly selected locations for tests of the density, the Engineer may also isolate from a nortnal lot any area lhat is suspected of being defective in relative density. Such isolated material will not include an original sample location. A minimum of 5 randomly located Page 22 of 50
