摘要
鉴于基质石油沥青良好的低温性能和硬质沥青突出的高温性能,研究中将硬质沥青以不同比例分别加入到70号基质沥青中制备出复合沥青,对复合沥青体系常规指标、布氏黏度、亲疏水性、车辙因子等性能进行检测,分析不同硬质沥青掺量下复合沥青性能指标变化规律,为行业提供技术支持。
In view of favorable low-temperature performance of matrix asphalt and prominent high-temperature performance of hard asphalt, a kind of compound asphalt was prepared by adding hard asphalt in different proportions into 70# matrix asphalt in this study. This paper tested the performances like regular indices, Brinell viscosity, hydrophilicity and rutting factor of compound asphalt, and analyzed the change rule of performance index of compound asphalt under different content of hard asphalt, which could provide technical support in the industry.
