【摘要】 通过常规试验和RV、DSR、BBR试验研究了胶粉目数对橡胶沥青性能影响规律。结果表明,基质沥青加入胶粉后,性能得到了明显改善,其中高标号的基质沥青改善效果明显。常规试验条件下胶粉掺量为20%,目数在20～60时,胶粉改性沥青性能较好。相应的SHRP试验结果,也证实了上述结果的可行性。更多还原

【Abstract】 In order to study the effect of the mesh on rubber modified asphalt performance,the routine testing and RV,DSR,BBR testing were did.The results showed;adding the crumb rubber to matrix asphalt, the performance had been significantly improved,especially the matrix asphalt of high mark.When the rubber powder content was 20%and from 20 to 60 of mesh,the soft point,ductility,penetration and elasticity recovery of modified asphalt were better.The corresponding test of SHRP also confirmed the feasibility of the above results.更多还原
