摘要
Abstract
Based on the dynamic triaxial experiment of a core wall asphalt concrete,this paper studies the influences on its dynamic characteristics by factors of confining pressure,consolidation ratio,bitumen aggregate ratio,etc.The results show that an increase in confining pressure or consolidation ratio is conducive to its capabilities of resisting dynamic loads,but such an increase leads to a reduction in its damping ratio.The bitumen aggregate ratio has a great influence on the dynamic properties.In the test range of asphalt concrete mixing proportion in this study,an increase in bitumen aggregate ratio considerably improves the resistance of asphalt concrete against dynamic loads.关键词
