National Center for Asphalt Technology Auburn University
Aggregate bulk specific gravity may be one of the least appreciated factors affecting the performance of asphalt pavements. Although high quality mixtures can be made with aggregates having a wide range in bulk specific gravity values, precisely determining the bulk specific gravity (Gsb) is critical to setting the optimum asphalt content of every mix design.
