This thirteenth version of the AASHTO Provisional criteria includes a entire set of forty-one provisional fabrics standards and try tools. All Provisional criteria are authorized for e-book via the AASHTO road Subcommittee on fabrics. Provisional criteria are criteria which were followed by means of the street 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 in the past 8 years is incorporated. At any time throughout the eight-year interval, the Subcommittee can poll to transform a Provisional typical right into a complete usual. The Subcommittee, to date, has switched over fifty eight Provisional criteria into complete criteria. those criteria are actually usually released within the AASHTO ordinary necessities for Transportation fabrics and techniques of Sampling and checking out.

8 165( s ) (XZ. 4) where: where: yb = the computed mean for the bottom slices; ym = the computed mean for the middle slices; st = ’s, = the computed variance for the bottom slices; and the computed variance for the middle slices. 78 to conclude that Gmbof the bottom and middle third slices are equal. 4. 1. Significant differences in the Gmb of the top and bottom slices relative to the middle third indicate a systematic variation in density within the specimen. 2. 025 have performed satisfactorily in the dynamic modulus, flow number, flow time, and continuum damage fatigue tests.

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.

2 The mass of HMA needed for each specimen will depend on the SGC specimen height, the Gmm of the aggregate, nominal maximum aggregate size, gradation (coarse or fme), and target air void content for the test specimens. Note 7-Appendix X1 describes a trial-and-error procedure developed in NCHRP 9-19 for determining the mass of HMA required to reach a specified test specimen target air void content for SGC specimens prepared to a height of 170 mm. 3 Perform conditioning for the test specimens and companion Gmmsample test in accordance with R 30.
