Description

 In recent years, expressway companies have adopted porous asphalt pavement in the surface layer of the pavement. As a result, with the conventional management criteria made for dense graded asphalt pavement, it is impossible to fully grasp the state of the pavement surface. In this study, the authors examine the adequacy of the current road surface management criteria and optimal road surface management criteria in terms of evaluation length and evaluation index. Firstly, the authors describe the deviation problem of results of the road surface condition survey and judgment of necessity for repair in practice. At that time, referring to the difference in the deterioration process between porous asphalt pavement and dense graded asphalt pavement, the authors point out the problems of the current road surface management criteria. In addition, the authors carry out empirical analysis that is based on the road surface condition survey data acquired from the expressway during service and study the optimal road surface management criteria. The analysis indicates that evaluation length should be shortened and the main evaluation index should be shifted to International Roughness Index from crack rate.
