Book Description
This paper presents the philosophy of the asphalt-aggregate mixture analysis system (AAMAS) concept and provides a brief discussion on those factors that must be included in the design of optimum paving mixtures based on performance-related criteria. Typically, the structural design of asphalt concrete pavements is based on assumed material properties (layer stiffness coefficients, resilient modulus, and fatigue or permanent deformation constants or both). After the structural design has been completed, materials are submitted and a mixture design is completed. The question then becomes: Does the as-placed material meet the assumptions used in structural design?.
