Abstract
In this study, the asphalt deformation of asphalt contained large stone was investigated in micro area. First, we measured by compression experimentally coefficient of longitudinal elasticity for small asphalt model specimens. Specimens have several volume fractions of reinforcement. In addition, finite element analysis of the model specimens was preceded for coefficient of longitudinal elasticity and distribution of stress and strain. Furthermore, a few composite laws were adapted these specimens. They, however, were limited by volume fractions. Therefore, based on the results of analysis and experiment, the variables of several mechanical properties and dimensions of stones in composite models changed to investigate for the minimum strain values of composite matrix. The results showed that structure of composite materials is more effective to optimize. Larger stones have near the surface, or, in intermediate layer have small stones that are better under the adaptive conditions.
