ONE APPROACH ON FORECASTING METHODS FOR POTHOLES TRIGGERED BY THE DETERIORATION OF THE COURSES DEEPER THAN BINDER COURSE OF POROUS ASPHALT PAVEMENT

排水性舗装の基層以深の劣化を要因としたポットホール発生予測手法の一提案

With an aim to grasp the damage progress on porous asphalt pavement, those data has been measured every other month using the high-accuracy pavement-condition measuring vehicle at the sites. Afterwards, it is confirmed that the cracks have progressed to potholes in a short time at the concerned place. Such the damages could not be detected and forecasted at their early stage with the traditional evaluation indicators (cracks, rutting, and surface roughness) and the conventional frequency of investigations. This paper is to propose (i) the new evaluation factors, the partial settlement values specific to porous asphalt pavement, based on the analysis of the high-accuracy surface profile, and (ii) the forecasting method of potholes occurrence, introducing the growth curve models for the damage progresses specific to the damage factors.　排水性舗装の損傷進行の把握を目的として，高精度な路面性状車両で，同一箇所の隔月計測を実施した結果，この場所では短期間でひび割れ発生からポットホールへ進展する事象を確認した．この様な損傷は従来の評価（ひび割れ，わだち，平坦性）指標や調査頻度では早期に発見，予測できない．本論文は，高精度で取得した路面の高さ情報を解析することで，排水性舗装特有の局所沈下量という新たな評価指標を提案するとともに，損傷要因に応じた損傷進行における成長曲線モデルを導くことで，ポットホール発生予測を提案するものである．
