I 1 fin, x 2 3 Where: 4 x = individual compaction test values for each sublot in the lot. 5 XX = summation of individual compaction test values 6 n = total number test values 7 8 2. Compute the sample standard deviation, "S", for each constituent: 9 10 S = r x' —�fix)` 21 n(n—1) 11 L I 12 Where: 13 >x2= summation of the squares of individual compaction test values 14 (1x)2 = summation of the individual compaction test values squared I 15 16 3. Compute the lower quality index (QL): 17 18 X —LSL = L S 19 20 Where: 21 LSL = 91.5 22 23 4. Determine PL (the percent within the lower Specification limit which 24 corresponds to a given QL) from Table 1. For negative values of QL, PL is equal 25 to 100 minus the table PL. If the value of QL does not correspond exactly to a 26 figure in the table, use the next higher value. 27 28 5. Determine the quality level (the total percent within Specification limits): 29 30 Quality Level = PL 31 32 6. Using the quality level from step 5, determine the composite pay factor (CPF) 111 33 from Table 2. 34 35 7. If the CPF determined from step 6 is 1.00 or greater: use that CPF for the 36 compaction lot; however, the maximum HMA compaction CPF using an LSL = 37 91.5 shall be 1.05. 38 39 8. If the CPF from step 6 is not 1.00 or greater: repeat steps 3 through 6 using an 40 LSL = 91.0. The value thus determined shall be the HMA compaction CPF for 41 that lot; however, the maximum HMA compaction CPF using an LSL = 91.00 42 shall be 1.00. 43 44 1-06.2(2)D4 Quality Level Calculation 45 The first paragraph (excluding the numbered list) is revised to read: 111 46 WEST MARINE VIEW DRIVE UTILITIES PAGE 5 OF 60 August 2018 WORK ORDER#3588 WSDOT AMENDMENTS Rev 4/2/18
