Digital image analysis of compacted asphalt mixture

In this paper, the technical feasibility of asphalt mixture digital image processing was explored. According to that the asphalt mixtures were designed with different compacting principles, so the internal structures and performances are different,we use the CCD camera to acquire the digital information in erect section of specimen,and adopt the evaluating parameter of compaction(direction of particle axis)to analyze the digital images directly and exactly. The real pavement structures were also compared; and the results show that the effect is good.
