This thirteenth variation of the AASHTO Provisional criteria encompasses a entire set of forty-one provisional fabrics requirements and attempt equipment. All Provisional criteria are licensed for booklet by way of the AASHTO street Subcommittee on fabrics. Provisional criteria are criteria that have been followed through 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 integrated. At any time through the eight-year interval, the Subcommittee can poll to transform a Provisional average right into a complete regular. The Subcommittee, to this point, has switched over fifty eight Provisional criteria into complete criteria. those criteria at the moment are usually released within the AASHTO regular standards for Transportation fabrics and strategies of Sampling and trying out.

Example text

1. This appendix presents a procedure for estimating the mass of HMA required to produce test specimens at a target air void content. It was developed to reduce the number of trial specimens needed to obtain a target air void content for a specific mixture. 2. This procedure can be used with either plant-produced or laboratory-prepared HMA. 2. 1. 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.

1 Using calipers, measure the diameter at the center and third points of the test specimen along axes that are 90 degrees apart. 1 mm. Calculate the average and the standard deviation of the six measurements. 5 mm. Reject specimens not meeting the average and standard deviation requirements listed in Table 1 . 1 mm, shall be used in all material property calculations. 2 Measure the height of the test specimen in accordance with ASTM D 3549. Reject specimens with an average height outside the height tolerance listed in Table 1 .

9. Determine the air void content of the fourth and fifth trial test specimens. 10. Plot the air void content of the third, fourth, and fifth trial test specimens on the y axis versus the mass of HMA used to prepare the SGC specimen on the x axis, and draw the best-fit line through the three data points. 11. From the best-fit line, determine the mass of HMA needed to produce a test specimen with the target air void content. 12. 11 as the target mass for test specimen production. 4. 1. The method described in this appendix was developed by the Arizona State University during NCHRP 9-19.
