Subtract this number <br />from 100.00. The resulting number is the value to be used in the next step (Step 8) for the <br />calculation of quality level. <br />(8) Calculate the percent within limits (PWL) = (Pu + PL) - 100 <br />(9) Calculate the Pay Factor (PF) for each quality characteristic using the <br />equation given in 334 - 8.2.2.2. <br />Table 334 -7 <br />Specification Limits <br />Quality Index <br />Percent within Limits for Selected Sample Size <br />Quality Characteristic <br />n= 4 <br />Specification Limits <br />Passing No. 8 [2.36 mm] sieve ( percent) <br />Target <br />± 3.1 <br />Passing No. 200 [75 m] sieve ( percent) <br />Target <br />± 1.0 <br />Asphalt Content ( percent) <br />Target <br />± 0.40 <br />Air Voids — Coarse Mixes ( percent) <br />4.00 ± <br />1.40 <br />Air Voids — Fine Mixes ( percent) <br />4.00 ± <br />1.20 <br />Density — Coarse Mixes ( percent of Gmm): <br />94.50 <br />± 1.30 <br />Density — Fine Mixes ( percent of Gmm): <br />93.00 <br />+ 2.00, - 1.20 0 ) <br />Note (1): If the Engineer (or Contract Documents) limits compaction to the static mode <br />only, the specification limits are as follows: 92.00 + 3.00, -1.20.
