Metropolitan Expressway Kanagawa No. 3 Kariba Line (length 10.2km) was gradually opened from 1983 to 1989 year. The pavement of around 3.4km length road constructed with opened earthwork near the end of Kariba line is suffered damage relatively more common, and often was repaired and modified. In this paper, the causes of pavement damage have been examined by the geotechnical method. The study on the effect of drainage measures was performed by the seepage flow FEM analysis. And the testing using the new drainage was conducted, installing many monitoring equipments in the roadbed. The drainage effect was confirmed by the observations of groundwater head and pore water pressure.
