Evaluation of the Supplemental Procedure of the Maximum Specific Gravity Test for Bituminous Paving Mixtures
The objective of the study was to investigate the effects of performing the supplemental procedure of AASHTO T 209 (or ASTM D 2041) on the percent air voids, the effective aggregate specific gravity, and the maximum specific gravity of a bituminous paving mixture, using both thoroughly coated aggregates and partially coated aggregates. The supplemental procedure should correct the test data for water absorbed into the aggregate during the test. Although the supplemental procedure can be used when designing mixtures, it is most often used for determining the maximum specific gravities of moisture damaged pavement samples, or cores or specimens where sawing has exposed a significant amount of aggregate. The majority of aggregates used in the study had water absorptions below 2.5 percent and thus were not highly absorptive.
