沥青混合料的空隙率是路面质量控制体系中的重要指标,对其进行科学的评价对路面质量的控制具有十分重要的意义。国内外对空隙率的分布做了大量的研究,但并未对空隙率的空间连续分布做深入的探讨。本文基于三维立方卷积法对路面空隙的分布进行研究,建立空隙率的最优三维连续分布模型。研究表明:基于三维立方卷积法的路面空隙率分布模型能够很好的反映路面空隙率分布特性,能够对路面的离析类型进行精准的判断。
The voidage of asphalt mixture is an important index in the pavement quality control system. It is of great significance to conduct scientific evaluation on the pavement quality control. A great deal of researches have been done on the distribution of porosity in China and abroad. However, the spatial distribution of porosity has not been explored deeply. In this paper, based on the three-dimensional cubic convolution method to study the distribution of pavement voids, the establishment of optimal three-dimensional porosity distribution model. The research shows that the model of void distribution based on three-dimensional cubic convolution can well reflect the distribution of void fraction of pavement, and can accurately determine the type of pavement segregation.
