Specifications

Specifications include, but are not limited to: The intent of AASHTO T 209-12, Standard Method of Test for Theoretical Maximum Specific Gravity and Density of Hot Mix Asphalt (AASHTO T 209), is to remove all air from a loose asphalt mix sample, thus establishing the theoretical maximum specific gravity (Gmm). During the test, the sample is placed in a container, covered with water, and subjected to a vacuum of 3.7 0.3 kPa for 15 m while vibrated mechanically or manually to reduce the air remaining in the sample to the absolute minimum. If there is any air in the sample at the end of the test, the test results will reflect something less than the true Gmm value.
