This thirteenth variation of the AASHTO Provisional criteria features a entire set of forty-one provisional fabrics necessities and try out tools. All Provisional criteria are licensed for ebook by means of the AASHTO street Subcommittee on fabrics. Provisional criteria are criteria which were followed by means of the road Subcommittee on fabrics on a brief 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 in the course of the eight-year interval, the Subcommittee can poll to transform a Provisional normal right into a complete common. The Subcommittee, to this point, has switched over fifty eight Provisional criteria into complete criteria. those criteria are actually usually released within the AASHTO normal necessities for Transportation fabrics and strategies of Sampling and trying out.

Coefficient of variation of the dynamic modulus; and 4. Standard deviation of the phase angle. Figure 1 presents an example summary data sheet. Figure l-Example Dynamic Modulus Summary Sheet 10. 1 General Form-The general form of the dynamic modulus master curve is a modified version of the dynamic modulus master curve equation included in the Mechanistic-EmpiricalPavement Design Guide (MEPDG). (Max - 6) logIE*l= + 1 + k)+ylog f, where: TS-2d IE*l = the dynamic modulus, psi; 6, p, and y Max = = f, = the fitting parameters; the limiting maximum modulus, psi; and the reduced frequency, Hz.

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 .
Trial test specimens are prepared as described in this standard practice from SGC specimens produced with a standard mass of 6650 g and compacted to a standard height of 170 mm. 2. Based on the air void content of the trial specimens, the mass of HMA required to produce test specimens at a target air void content is estimated using a regression equation. 4. 3. To use this method, it is critical that all SGC specimens are prepared to a standard height of 170 mm. 4 can be used to develop a similar equation for other SGC specimen heights.
