HMA Weight-Volume Terms and Relationships - Pavement

Basic HMA weight-volume relationships are important to understand for both mix design and construction purposes. Fundamentally, mix design is meant to determine the volume of asphalt binder and aggregates necessary to produce a mixture with the desired properties (Roberts et al., 1996 [1]).). However, since weight measurements are typically much easier, they are typically taken then converted ...
