 note = {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 states of the pavement surface. In this study, the authors examine
the validity 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.},
