This thirteenth version of the AASHTO Provisional criteria encompasses a entire set of forty-one provisional fabrics requirements and try out equipment. All Provisional criteria are authorized for book via the AASHTO road Subcommittee on fabrics. Provisional criteria are criteria which were followed via the road Subcommittee on fabrics on a short lived foundation for a greatest of 8 years. A chronology of the year-to-year prestige of the Provisional criteria prior to now 8 years is integrated. At any time through the eight-year interval, the Subcommittee can poll to transform a Provisional regular right into a complete average. The Subcommittee, up to now, has switched over fifty eight Provisional criteria into complete criteria. those criteria are actually usually released within the AASHTO general necessities for Transportation fabrics and strategies of Sampling and trying out.

Y, = the variance of the Gmb of the slices; and the measured G m b of each slice. 6. Statistical Comparison of Means-Compare the mean G m b of the top and bottom slices to the middle slice using the hypothesis tests described below. In the descriptions below, the subscripts t, m, and b refer to the top, middle, and bottom slices, respectively. 1. Check the top slice relative to the middle slice. Null Hypothesis The mean Gmb of the top slice equals the mean Gmb of the 2 middle slice, p; = p m .
15”K) is used as the reference temperature. 1, into Equation 3. 2 Determine the four fitting parameters of Equation 3 (6, p, y, and AEa)using numerical optimization. The optimization can be performed using the “Solver” function in Microsoft Excel@. This calculation is performed by a spreadsheet to compute the sum of the squared errors between the logarithm of the average measured dynamic moduli at each temperature/frequency combination and the values predicted by Equation 3. The “Solver” function is used to minimize the sum of the squared errors by varying the fitting parameters in Equation 3.
100-R.. G- ' = "1 se where: G,, = the effective specific gravity of the shingle aggregate; G,,,,,, = the theoretical maximum specific gravity of the RAS; and Pb, = the percentage of shingle asphalt binder in the RAS by mass, percent. Note 3-The absorption of most shingle aggregate is so low that little difference exists between the bulk and apparent specific gravities. Therefore, the effective specific gravity of the shingle aggregate may be substituted for the bulk specific gravity in subsequent calculations.
