一种基于数字图像处理技术的沥青混合料均匀性研究新方法

A New Way to Study Homogeneity of HAM Based on Digital Image Disposal Technology

基于数字图像处理技术,本文对沥青混合料中集料的分布状态,即沥青混合料均匀性进行直接研究。研究结果表明:从沥青混合料中集料的分布位置和分布数量两方面考虑,结合面积比k这一系数,沥青混合料的均匀性能够在数值上进行评价。

Based on digital image processing techniques,this paper studied directly the aggregate distribution in HMA,named by homogeneity of HMA.The research results indicate that in HMA if aggregate distributed situation,aggregate distributed number and area ratio coefficient,which is defined as the ratio of the area of aggregates retained on the same sieve size to the area of whole aggregates in a section are considered comprehensively,it is possible to quantitatively assess homogeneity of HMA.
