摘要
主要研究应用小梁弯拉试验、直接拉伸试验,考查了在普通沥青混合料中掺适量丁苯橡胶后对低温抗裂性能的改善效果,同时与国外的优质沥青作比较。
Through bend-tensile test and extension test, application is carried out to check the low temperature crack resistance with proper butadienestyrene rubber in common bitumen mixture material, and comparison is made with the foreign high-quality bitumen.
