【Abstract】 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.更多还原
