Abstract
It is indispensable to know the establishment of material property evaluation method and the material influence proportion in order to understand the flow deformation resistance of the asphalt mixture. In this study, focusing on the viscoelasticity of the polymer modified bitumen and geometrical properties of coarse aggregates, their measuring and evaluation methods were examined. The examination of relation between the obtained material property values and porous mixture properties revealed that mortar consisting of asphalt and aggregate granules is highly correlated with the dynamic stability of mixture and that the flow deformation of mixture is more influenced by the microtexture of coarse aggregate surface rather than large geometrical properties such as coarse aggregate flatness.
