摘要
利用X-ray CT技术,获取沥青混合料内部结构组成,分析体积参数,进而完成沥青混合料的计算机辅助设计的研究已成为沥青路面技术领域的关注热点.重点介绍了在利用X-ray CT进行沥青混合料体积组成分析与差异性物质辨识、混合料内部结构组成的三维图像重构、沥青混合料性能的虚拟试验等方面研究时存在的问题和可能的解决方法.同时,提出了进一步研究所需要解决的一些关键技术,给出了一个技术路线图以供日后的研究参考.
It has become a concerning focus in the field of asphalt pavement that using X-ray CT to obtain the internal structure of asphalt mixtures,analyze the volume parameter and finish the computer aided design of asphalt mixtures.In this paper,some existing problems and possible solution methods are introduced during the research of using X-ray CT to analyze the volume composition and to distinguish different material of asphalt mixtures,3D image reconstruction of asphalt mixtures＇ structure composition and simulate test of asphalt mixtures＇ performances.Some key technology is putforward and an advised technical road map is provided as a reference for research in the future.
