This thirteenth version of the AASHTO Provisional criteria incorporates a entire set of forty-one provisional fabrics necessities and try tools. All Provisional criteria are licensed for book by means of the AASHTO road Subcommittee on fabrics. Provisional criteria are criteria which were followed by means of the street 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 in past times 8 years is incorporated. At any time throughout the eight-year interval, the Subcommittee can poll to transform a Provisional normal right into a complete usual. The Subcommittee, up to now, has switched over fifty eight Provisional criteria into complete criteria. those criteria are actually on a regular basis released within the AASHTO common requirements for Transportation fabrics and strategies of Sampling and trying out.

The release of shingle asphalt binder into the virgin asphalt binder can result in reduced virgin asphalt binder requirements. It is unlikely, however, that all of the shingle asphalt binder will dissolve and blend with the virgin asphalt binder. Particles of undissolved shingle asphalt binder may act like aggregate particles that require more virgin asphalt binder to accomplish coating. Additionally, particles of shingle asphalt binder may absorb bituminous oils from the virgin asphalt binder.
Establish the required PG (or critical temperatures for the high, intermediate, and low properties) for the virgin asphalt binder in accordance with M 323. This procedure can be accomplished by constructing a blending chart and plotting the critical temperature of the shingle asphalt binder for 100 percent shingle asphalt binder and the value of Pb,fon the chart abscissa to determine the critical temperatures of virgin asphalt binder that must be used in the new HMA. The blending chart approach in M 323 considers the effect of reclaimed asphalt pavement (RAP) on the virgin asphalt binder PG; in this practice, the effect of RAS is evaluated instead.
