Abstract :
The microstructure of the fine aggregate matrix has a significant influence on the mechanical properties and evolution of damage in an asphalt mixture. This paper presents the findings from a study conducted to identify a quantitative method to characterize the three-dimensional microstructure of the matrix in an asphalt mixture. The influence of binder content, coarse aggregate gradation, and fine aggregate gradation on the microstructure of the matrix was also investigated. Results indicate that for a given aggregate type, binder content and aggregate gradation influence the degree of anisotropy whereas gradation of the coarse aggregate has the most influence on the direction of anisotropy of the asphalt mastic. Addition of asphalt binder or adjustments to the fine aggregate gradation also resulted in a more uniform spatial distribution of the asphalt mastic.
