Development of automation technique for check and diagnosis of pavement and earthfill structure

Abstract

The maintenance work of pavement is often planned based on MCI and FWD data. However, the repeated damages of pavement are observed at many places. This surface damage of pavement is partly originated by the weakness of subgrade, damage of the filled up ground and ground water. In order to avoid repeated maintenance works of pavement, the condition of earthfill structure should be evaluated by an easy logging technique from pavement surface. In this paper, the automation technique for check and diagnosis of pavement as well as earthfill structure is proposed by using surface wave logging and electric resistivity. The efficiency of the proposed system is discussed based on some case studies.
