This thirteenth version of the AASHTO Provisional criteria encompasses a entire set of forty-one provisional fabrics requisites and attempt equipment. All Provisional criteria are authorized for book through the AASHTO road 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 in the past 8 years is integrated. At any time throughout the eight-year interval, the Subcommittee can poll to transform a Provisional typical right into a complete typical. The Subcommittee, thus far, has switched over fifty eight Provisional criteria into complete criteria. those criteria are actually usually released within the AASHTO regular requirements for Transportation fabrics and techniques of Sampling and trying out.

Calculate the average air void content of the two specimens, and designate this value as Va,. 4. 1. 1) vas where: Wt = Vat Va, = = the estimated mass of HMA required to produce a SGC specimen for a test specimen with a target air void content of Vat,g; the target air void content for the test specimen, % by volume; and the test specimen air void content produced with a gyratory mass of 6650 g, % by volume. 5. 4 and compacted to the standard height of 170 mm. 6. Determine the air void content of the third trial test specimen.

Although RAS has been used as an additive in HMA in the United States for over 15 years, it remains a relatively new application. As a result, there are design considerations that are not generally known to the specification user. Four separate areas are addressed by this recommended practice, with each elaborating on and providing recommendations relative to the following: W Design Considerations When Using RAS in HMA W Determining the Shingle Aggregate Gradation and Specific Gravity W Estimating the Contribution of the Shingle Asphalt Binder to the Final Blended Binder in New HMA (Values of F ) W Determining the Performance Grade (PG) and Percentage of the Virgin Asphalt Binder in New HMA 4.

8. virgin asphalt binder-for the purpose of this specification, shall mean new performance-graded asphalt binder to be used in the new HMA. 9. final blended binder-for the purpose of this specification, shall mean the mixture of virgin asphalt binder and shingle asphalt binder. 10. virgin a g g r e g a t e f o r the purpose of this specification, shall mean coarse and fine aggregate introduced into new HMA that is exclusive of the shingle aggregate. 1 1. new HMA-for the purpose of this specification, shall mean HMA manufactured using aggregates, recycled asphalt pavement (if used), virgin asphalt binder, and reclaimed asphalt shingles.
