Several methods have been developed for determining the quantities of aggregate and asphalt cement used in asphalt concrete. This research consists of the evaluation of the surface area of different aggregates used in the state of West Virginia. This factor is important because the amount of asphalt needed to coat the aggregate depends on the specific surface area of the aggregate blend. The specific surface area of the aggregate blend is usually calculated based on the aggregate gradation and surface area factors.;This research proposes a method to obtain accurate specific surface area factors using the Blaine air permeability apparatus. By using the factors obtained, the voids in the mineral aggregate (VMA) and asphalt thickness are calculated. The measured specific surface area of the crushed limestone fines is much greater than the values computed using the traditional approach. This implies that the asphalt concrete made with 100 percent crushed material will have a much thinner asphalt film thickness than was considered adequate when the volumetric mix design criteria were developed.
