Abstract
The lateral movement of abutment has induced significant problems in the terms of either construction and management since 1990 in South Korea. The research related to this issue has been also paid wide attention. In order to overcome these problems, modified lateral float, sand compaction method (SCP), and pile-slab method have been developed. Especially, the EPS was extensively used in the soft ground to either prevent or mitigate the lateral movement. Although th EPS is surely effective on reducing lateral movement of abutment and load during the construction, cracks and deterioration may be found on the pavement in the EPS section after opening the road. In this study, structural performance test and eye investigation of drilling cores from the site where the EPS was widely applied were conducted and analyzed.
