- Abstract
Based on the study of image processing algorithm,the Sub-Microstructure Analysis System of Asphalt Concrete(MASAC) suitable for Windows Operating System was specially programmed.In this paper the index system of MASAC is chiefly illustrated and the functions of a part of indexes are briefly introduced.The index system is classified into 5 types,i.e.characteristics of aggregate particles,arrangement of aggregate particles,contact among aggregate particles,air voids between aggregate particles and distribution of aggregate particles.By analysis for the microstructure of asphalt concrete,it can be used to investigate the internal relationship between asphalt concrete microstructure and macro-performance,and evaluate the asphalt mixture homogeneity.
