关于沥青混合料的均匀性和离析问题

On Issues of Homogeneity and Separation of Bitumen Mixtures

从沥青路面的水损害破坏出发 ,指出沥青混合料的离析和不均匀问题是造成水损害破坏的根本原因 ,介绍评定路面离析和不均匀的无破损测试方法 ,分析造成离析及不均匀的影响因素 ,离析对混合料性能的影响 ,以及如何防止离析及不均匀的技术措施。

This paper analyzes the water damage of bitumen pavement, and points out that separation and non-homogeneity of the bitumen mixtures are the radical cause of the water damage. Non-destructive test method is introduced to evaluate the separation and nonhomogeneity of road pavement. Impact factors to cause separation and non-homogeneity are analyzed, as well as the impacts on the performance of the bitumen mixtures and the preventive measures.
