| The asphalt mixture with CRM(Crumb Rubber Modifier) is known to show a better performance in resisting thermal cracking, fatigue cracking, and rutting compared with the conventional mixture. In this research, the lab tests on the physical and the mechanical characteristics of the domestic crumb rubber modified asphalt binder and conventional asphalts (AP-3, AP-5) were conducted. The physical test results show that CRM asphalt has better physical characteristics than that of conventional asphalts. The dynamic shear rheometer test results in high temperature show that CRM asphalt has higher complex shear modulus and aging resistance than those of conventional asphalts. And, the bending beam rheometer in low temperature test results show that CRM asphalt has higher resistance to thermal cracking than that of conventional asphalts. |
