Document Summary
Asphalt mixture design allows for the selection of an optimum amount of asphalt cement content to satisfy a prescribed volumetric and densification criteria. To ascertain the volumetric criteria of the voids in the total mix (vtm), the voids in the mineral aggregate (vma), and the. Voids filled with asphalt (vfa), engineers use the weight-volume relationship or specific gravity (relative density) due to the impracticality of direct volume measurements. Following the procedures outlined in astm d 2726, bulk specific gravity and density of non-absorptive. Superpave, which stands for superior performing asphalt pavement, mixture design awards practitioners the ability to accurately assess compacted hot mix asphalt which consists of both coarse and fine aggregate, asphalt cement, and air. The calculated values can all be utilized in determining the perceived performance of the asphalt mixture and if the asphalt mixture meets specified requirements.
