两种沥青在LSPM沥青混合料中的路用性能对比

Relation of Physical Properties and Chemical Compositions of Asphaltite Modified Asphalts

采用一种新型的改性沥青用于大粒径透水性沥青混合料中,通过与传统应用的MAC沥青进行对比,探讨新型改性沥青在LSPM混合料中的可行性和路用特点,期望为LSPM混合料技术提供一个沥青选择方案。

A new type of modified asphalt is used in the large size permeable asphalt mixture. Through the comparison with the traditional MAC asphalt,the feasibility and the road characteristics of the new modified asphalt in the LSPM mixture are discussed. It is expected to provide a bitumen selection case for the LSPM mixture technology.
