The target density for coarse <br />mixes is 94.50 percent of Gmm. The target density for fine mixes is 93.00 percent of Gmm <br />(92.00 percent when compaction is limited to the static mode as defined in Note 1 of <br />Table 334 -7) <br />334 -8.2.2 Three or More Sublot Test Results: When three or more sublot <br />test results are available for a LOT, the variability- unknown, standard deviation method will <br />be used to determine the estimated percentage of the LOT that is within specification <br />limits. The number of significant figures used in the calculations will be in accordance with <br />requirements of AASHTO R 11-82 (2002), Absolute Method. <br />334 - 8.2.2.1 Percent Within Limits: The percent within limits (PWL) <br />and Pay Factors for the LOT will be calculated as described below. Variables used in the <br />calculations are as follows: <br />x <br />= individual test value (sublot) <br />n <br />= number of tests (sublots) <br />S <br />= sample standard deviation <br />r(x2) <br />= summation of squares of individual test values <br />(Ex)2 <br />= summation of individual test values squared <br />Qu <br />= upper quality index <br />USL <br />= upper specification limit (target value <br />specification limit from Table 334 -7) <br />QL <br />= lower quality index <br />LSL <br />— lower specification limit (target value <br />specification limit from Table 334 -7) <br />Pu <br />= estimated percentage below the USL <br />PL <br />= estimated percentage above the LSL <br />(1) Calculate the arithmetic mean (X)of the test values: <br />X =�l <br />n <br />(2) Calculate the sample standard deviation (s): <br />plus upper <br />minus lower <br />March 2007 01000 -68 03- 4122.D <br />
