Research on high viscosity asphalt based mixture on shearing properties

LIU Zhao-hui,OU-YANG Sheng,SHA Qing-lin(College of Highway Engineering,Changsha University of Science and Technology,Changsha 410076,China)  
Superpave Shear Test and Uniaxal penetration test are carried on high viscosity asphalt based mixture,asphalt mixture for paving heavy traffic road and SBS modified asphalt mixture,contrasting to study the difference of three kinds of different mixtures in shear resistance to high temperature.The result shows that: high viscosity asphalt based mixture is better than normal asphalt based mixture for paving heavy traffic road and SBS modified asphalt mixture in aspect of shear resistance to high temperature,which can be applyed to the southern hot and damp region,and this can produce a good social and economic performance.
