Abstract:

in order to find an available way to control the pavement quality in construction process,a method of detecting and evaluating the surface segregation of asphalt pavement was presented.This method based on the digital image technique includes three parts,i.e.,the detection of segregation,the definition of non-segrega-tion and the evaluation of segregation levels.The results of the parallel test indicate that the proposed method combines a precision suited to the pavement engineering and the advantages of low cost and facility,and it is helpful to improve the pavement quality and to prolong the pavement life.

Key words: asphalt pavement, surface segregation, digital image technique
