Determine PL (the percent within the lower Specification limit which corresponds 20 to a given QL) from Table 1. For negative values of QL, PL is equal to 100 minus 21 the table PL. If the value of QL does not correspond exactly to a figure in the 22 table, use the next higher value. 23 II 24 5. Determine the quality level (the total percent within Specification limits): 25 um 26 Quality Level = PL I 27 28 6. Using the quality level from step 5, determine the composite pay factor (CPF) 29 from Table 2. 30 II31 7. If the CPF determined from step 6 is 1.00 or greater: use that CPF for the 32 compaction lot; however, the maximum HMA compaction CPF using an LSL = 33 91.5 shall be 1.05. I 34 35 8. If the CPF from step 6 is not 1.00 or greater: repeat steps 3 through 6 using an 36 LSL = 91.0. The value thus determined shall be the HMA compaction CPF for 37 that lot; however, the maximum HMA compaction CPF using an LSL = 91.00 38 shall be 1.00. 39 I 40 1-06.2(2)D4 Quality Level Calculation 41 The first paragraph (excluding the numbered list) is revised to read: 42 t 43 44 The procedures for determining the quality level and pay factors for a material, other than HMA compaction, are as follows: 45 I I
