Abstract:

Current practices for asphalt mix design and acceptance testing rely on volumetric properties. Vital to the calculation of mix volumetric properties are specific gravity measurements of the mixture and the aggregate in the mixture. In essence, the specific gravity measurements are conversion factors which allow conversion of mass percentages to volume proportions/percentages. The accuracy and reliability of the specific gravity measurements are therefore fundamental to the business of building quality hot-mix asphalt (HMA) pavements. This Technical Brief summarizes a critical review of specific gravity measurement methods. The objectives of this review are to summarize problems and issues with current methods, examine possible improvements and/or alternate methods, and identify areas that need further research and development.
