应用构造深度表征沥青路面的离析

为了研究沥青路面的离析，在生产实践分析的基础上提出离析的本质是沥青混合料颗粒组成、混合料结构和空隙结构存在的变异。其具体表现形式是三者独自或组合出现的状态。之后为了判别离析，提出以表面特性指标——构造深度分析离析的方法，并分析了路面检测构造深度数据的概率分布函数，证明其符合正态分布。最后设计不同级配和变异的同一级配沥青路面的构造深度实验，验证了以构造深度判别沥青路面离析的可行性。

Study on Segregation of Asphalt Pavement Indicated with Texture Depth

On the base of segregation analysis of asphalt pavement in highway construction, the essence of segregation is considered as gradation change, mixture structure and void structure variations. Representations of asphalt pavement segregation are appeared as one or more status of independent or combination of changes in gradation, mixture structure and void structure. The method of distinguishing segregation with texture depth was suggested. And it is proved that the distribution function of texture depth is in line with normal distribution, The texture depth test design is presented with different gradation and variations on asphalt pavements of same gradations, which validated the feasibility of the method.
