摘要
在阐述改性机理的基础上 ,对两种基质沥青及四种改性剂量的低密聚乙烯 (LDP)E改性沥青进行了常规的试验研究 ,深入分析了改性前后沥青各技术指标的变化原因 ,指出了LDPE对于基质沥青高低温性能 。
On the basis of introduction of modified mechanism, two types of asphalt and four various LDPE content modified asphalt were tested, the reasons that some values have been changed before and after modified were analyzed deeply, and the function of LDPE for high and low temperature performance and aging performance of asphalt were put forward.
