The target density for coarse mixes is 94.50 percent of Gmm. The target density for fine mixes is 93.00 percent of Gm (92.00 percent when compaction is limited to the static mode as defined in Note 1 0 Table 334-7) 2 Sublot Test Average Deviation 0.00-0.35 0.36-0.71 0.72-1.41 1.42-2.12 >2.12 334-8.2.2 Three or More Sublot Test Results: When three or more sublot test results are available for a LOT, the variability-unknown, standard deviation method will be used to determine the estimated percentage of the LOT that is within specification limits. The number of significant figures used in the calculations will be in accordance with requirements of AASHTO R 11-82 (2002), Absolute Method. 334-8.2.2.1 Percent Within Limits: The percent within limits (PWL) and Pay Factors for the LOT will be calculated as described below. Variables used in the calculations are as follows: x = individual test value (sublot) n = number of tests (sublots) s = sample standard deviation ~(X2) = summation of squares of individual test values (~X)2 = summation of individual test values squared Qu = upper quality index USL = upper specification limit (target value plus upper specification limit from Table 334-7) QL = lower quality index LSL = lower specification limit (target value minus lower specification limit from Table 334-7) Pu = estimated percentage below the USL PL = estimated percentage above the LSL (1) Calculate the arithmetic mean (X )of the test values: - I> x=- n (2) Calculate the sample standard deviation (s): March 2007 01000-68 03-4122.0
