This thirteenth variation of the AASHTO Provisional criteria includes a whole set of forty-one provisional fabrics requirements and attempt tools. All Provisional criteria are authorized for e-book by means of the AASHTO road Subcommittee on fabrics. Provisional criteria are criteria which were followed by way of 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 incorporated. At any time in the course of the eight-year interval, the Subcommittee can poll to transform a Provisional regular right into a complete regular. The Subcommittee, to date, has switched over fifty eight Provisional criteria into complete criteria. those criteria at the moment are on a regular basis released within the AASHTO normal requisites for Transportation fabrics and strategies of Sampling and checking out.

Specific guidance includes design considerations, how to determine the shingle aggregate gradation, how to determine the performance grade (PG) and percentage of the virgin asphalt binder, and how to estimate the contribution of the shingle asphalt binder to the final blended binder. Note l-Refer to MP 15 for information specifying the use of RAS in HMA. Additionally, refer to the White Paper for Recycled Asphalt Shingle as an Additive in Hot-MixAsphalt for more details concerning the origins and development of this recommended practice.

2. Determine the percentage of shingle asphalt binder (Pbr)present in the RAS in accordance with T 164, T 170, or T 319. 3. 2) expressed as a decimal; and the percentage of final blended binder in the new HMA expressed as a decimal. 05. 15 = 23 percent of the final blended binder is contributed by RAS. 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.
