“…asphalt concrete on top of a base course on top of the subgrade) based on surface deflections. The damage indices are also obtained based on the measured surface deflection of pavement (Takeuchi et al, 2011, Kawana et al, 2013, Ishita et al, 2014. It is very difficult to investigate the lower part of subgrade and the stability of embankment and natural ground.…”

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.
