| Research Abstract |
Transient performance of distresses of asphalt pavements in cold area and ware area. that is, Tohoku area and Kyushu area respectively, was evaluated by analyzing the data of the condition survey of pavements. In the analysis, Markov chain model was applied to evaluate the variation of the transient performance of the asphalt pavement distresses. In the case of the warn area, most of the pavements were repaired before their ultimate failure stage. Then, the transient performance model of asphalt pavement distress was formulated by applying the Weibull function to the surveyed data in order to evaluate the distress performance during the life of asphalt pavement.
