Abstract
The deterioration of pavement structure is a complex phenomenon that follows the deterioration of both pavement surface and pavement sub-surface. In addition, the deterioration progress of pavement sub-surface affects the deterioration speed of pavement surface. The road pavement management is important to determine the optimal repair strategy which considers the deterioration of both pavement surface and sub-surface (hereafter call "pavement structure"). This study proposes pavement repair planning and strategies of 1) extraction of key management section of relative evaluation based on road inspection survey results, and 2) determination of decision-making repair methodologies based on pavement structural soundness survey by FWD (Falling Weight Deflectometer) in key management sections. In addition, the National Highway Route 9 is the target area as empirical study to verify the methodology proposed in this study.
