摘要
阐述了重载和超载问题的现状和危害,通过不同用油量和不同成型压力下制得的旋转压实试件,研究了荷载对沥青混合料永久变形的影响,提出了采用GTM或采用SHRP的旋转压实仪但加大试件的成型压力这两种设计方法,求解决重载和超载问题的建议。
This paper illustrates the present status and the harm of heavy loading and over loading issues. The research on the effects of loading to the permanent deformation of asphalt mixture has been performed through producing the rotary press test samples under different forming press with different oil consumption. Two approaches in design, the adoption of GTM or SHRP rotary press equipment with increased forming press, have been raised as suggested solutions to heavy loading and over loading issues.
