摘要
为了寻求一种干法工艺以改善沥青混合料的低温性能,文中基于低温弯曲破坏试验,在沥青混合料中干法掺入多种外掺剂.对比试验结果发现,新型橡维联材料改性沥青混合料的低温弯曲破坏应变不低于SBS、SBR改性沥青混合料,且在工艺方面,干法掺入更为快速便捷.
Abstract
In order to find a dry process to improve the low temperature performance of asphalt mixture,based on the low temperature bending failure test,a variety of additives were mixed into asphalt mixture by dry method.The results showed that the low temperature bending failure strain of the modified asphalt mixture was not lower than that of SBS and SBR,and the dry method was faster and more convenient.
