Analysis of factors influencing road performance of graphene-basalt fiber asphalt mixtures
摘要
Abstract
The graphene-basalt fiber asphalt mixtures(GBFAM)is a new composite modified material.In order to explore its road performance evolution characteristics and its influencing factors,on the ba-sis of mixing ratio design,through wheel tracking,low-temperature bending beam,freeze-thaw splitting tests and the use of the response surface methodology,the influences of graphene content,basalt fiber content,and asphalt aggregate ratio on the dynamic stability,maximum bending strain,and freeze-thaw tensile strength ratio were analyzed,along with their significance levels.The results demonstrate that within a certain range of variation based on the optimum graphene content of 0.20％,optimum basalt fiber content of 0.30％and optimum asphalt aggregate ratio of 5.32％,the dynamic stability,maximum bending strain,and freeze-thaw tensile strength ratio of the graphene-basalt fiber asphalt mixture tends to increase and then decrease with increasing graphene content,basalt fiber content,and asphalt aggre-gate ratio,reaching a maximum value near the optimum asphalt aggregate ratio,as well as the optimum graphene and basalt fiber contents.Among them,the asphalt aggregate ratio has a very significant in-fluence on the dynamic stability,maximum bending strain,and freeze-thaw tensile strength ratio.The interaction between graphene and asphalt aggregate ratio has a significant influence on the maximum bending strain,and the effects of the remaining factors and their interactions are not significant.关键词
