Abstract
<p> This study is to analysis the deterioration of the asphalt pavement based on the inspection data of the national roads, focusing on the crack rate of the asphalt pavement at the transition process from stage II (maintenance stage) to stage III (repair stage), which were stipulated by the guideline of the pavement inspection issued at Oct. 2016. In the analysis, it was found that the deterioration progress of the crack rate for one year has statistically almost normal distribution, and we proposed a statistic method to predict the deterioration progress of the asphalt pavement. In addition, the concept of the reliability was introduced into the prediction method and the deterioration progress speed was calculated for each category of the traffic volume with the reliability. And we showed the occurrence probability of each stages on the deterioration of the asphalt pavements in the future across Japan.</p>
