| 摘 要： | 为了研究超大粒径沥青混合料(SLSM)的高温稳定性,在借鉴大粒径沥青混合料(LSAM)研究方法的基础上,确定SLSM的级配,并以SBS改性沥青作为粘结材料,利用车辙试验的动稳定度评价SLSM的高温性能,并与普通密级配沥青混合料进行比较。结果表明:超大粒径沥青混合料的动稳定度比普通密级配沥青混合料的大17.07%,用作沥青路面的下面层满足要求。 |

High Temperature Stability of Super Large Size Mixture |

| Abstract: | In order to study the high temperature stability of super large size mixture(SLSM),the gradation of SLSM was determined on the basis of research methods for large stone asphalt mixtures(LSAM),SBS modified as-phalt was taken as the adhesive material,and the dynamic stability from rutting test was used to evaluate the high temperature performance of SLSM.In addition,and the results were compared with the dense graded asphalt mix-ture.The results indicate that the dynamic stability of SLSM is larger with 17.07... |
