I1 When using the nuclear density gaue for acceptance testing of 2 pavement density, the Engineer will follow WSDOT SOP 730 for I 3 correlating the nuclear gauge with HMA cores. When cores are 4 required for the correlation, coring and testing will be by the 5 Contracting Agency. When a core is taken for gauge correlation at the I 6 location of a sublot, the relative density of the core will be used for the 7 sublot test result and is exempt from retesting. 8 I 9 5-04.3(10)C3 HMA Statistical Compaction — Price Adjustments 10 For each HMA compaction lot (that is accepted by Statistical 11 Evaluation) which has less than three compaction sublots, for which I 12 all compaction sublots attain a minimum of 91 percent compaction 13 determined in accordance with FOP for WAQTC TM 8 (or WSDOT 14 SOP 736 when provided by the Contract), the HMA will be accepted 15 at the unit Contract price with no further evaluation. 16 17 For each HMA compaction lot (that is accepted by Statistical 18 Evaluation) which does not meet the criteria in the preceding I19 paragraph, the compaction lot shall be evaluated in accordance with 20 Section 1-06.2(2) to determine the appropriate Compaction Price 21 Adjustment (CPA). All of the test results obtained from the I 22 acceptance samples from a given compaction lot shall be evaluated 23 collectively. Additional testing by either a nuclear density gauge or 24 cores will be completed as required to provide a minimum of three I 25 tests for evaluation. 26 27 For the statistical analysis in Section 1-06.2, use the following values: I 28 29 x = Percent compaction of each sublot 30 USL = 100 1 31 LSL= 91 32 33 Each CPA will be determined as follows: II 34 35 CPA = [0.40 x (CPF — 1.00)] x Q x UP 36 37 Where 1 38 39 CPA = Compaction Price Adjustment for the compaction lot 40 ($) 41 CPF = Composite Pay Factor for the compaction lot I 42 (maximum is 1.05) 43 Q = Quantity in the compaction lot (tons) I 44 UP = Unit price of the HMA in the compaction lot ($/ton) 45 46 5-04.3(10)C4 HMA Statistical Compaction — Requests for I 47 Retesting 48 For a compaction sublot that has been tested with a nuclear density 49 gauge that did not meet the minimum of 91 percent of the theoretical 50 maximum density in a compaction lot with a CPF below 1.00 and thus 51 subject to a price reduction or rejection, the Contractor may request 52 that a core, taken at the same location as the nuclear density test, be I AMENDMENTS TO THE 2016 STANDARD SPECIFICATIONS BOOK Revised: 811/16
