【Abstract】 In order to find an available way to control t he pavement quality in construction process, a method of detecting and evaluating t he surface segregation of asphalt pavement was presented. This method based on t he digital image technique includes three parts, i.e., the detection of segregat ion, the definition of non-segregation 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 pa vement life.更多还原
