1 2. Compute the sample standard deviation, "S", for each constituent: <br /> 2 <br /> 3 S= <br /> L n(n-1) <br /> 4 <br /> 5 Where: <br /> 6 Ix2= summation of the squares of individual compaction test values <br /> 7 (Zx)2 = summation of the individual compaction test values squared <br /> 8 <br /> 9 3. Compute the lower quality index (QL): <br /> 10 <br /> , _ <br /> X —LSL <br /> 11 QI <br /> ` S <br /> 12 <br /> 13 Where: <br /> 14 LSL = 92.0 <br /> 15 <br /> 16 4. Determine PL (the percent within the lower Specification limit which corresponds <br /> 17 to a given QL) from Table 1. For negative values of QL, PL is equal to 100 minus <br /> 18 the table PL. If the value of QL does not correspond exactly to a figure in the table. <br /> 19 use the next higher value. <br /> 20 <br /> 21 5. Determine the quality level (the total percent within Specification limits): <br /> 22 <br /> 23 Quality Level = PL <br /> 24 <br /> 25 6. Using the quality level from step 5, determine the composite pay factor (CPF) <br /> 26 from Table 2. <br /> 27 <br /> 28 7. If the CPF determined from step 6 is 1.00 or greater: use that CPF for the <br /> 29 compaction lot; however, the maximum HMA compaction CPF using an LSL = <br /> 30 92.0 shall be 1.05. <br /> 31 <br /> 32 8. If the CPF from step 6 is not 1.00 or greater: repeat steps 3 through 6 using an <br /> 33 LSL = 91.5. The value thus determined shall be the HMA compaction CPF for <br /> 34 that lot; however, the maximum HMA compaction CPF using an LSL = 91.5 shall <br /> 35 be 1.00. <br /> 36 <br /> 37 1-06.2(2)D1 Quality Level Analysis <br /> 38 The following new sentence is inserted after the first sentence: <br /> 39 <br /> 40 The quality level calculations for HMA compaction are completed using the formulas in <br /> 41 Section 1-06.2(2)D5. <br /> 42 <br /> 43 1-06.2(2)D4 Quality Level Calculation <br /> 44 The first paragraph (excluding the numbered list) is revised to read: <br /> 45 <br /> 46 The procedures for determining the quality level and pay factors for a material, other than <br /> 47 HMA compaction, are as follows: 111 <br /> CITY OF EVERETT AMENDMENTS <br /> PACIFIC AVENUE TO INTERURBAN TRAIL BICYCLE SAFETY PROJECT 8/12/2019 <br /> STATE FUND#HLP PB17(014);COE#PW3688 Page AM-4 <br />
