An estimation method of degree of compaction on embankment slope using the non-destructive testing method

Research output: Contribution to conferencePaperpeer-review

Abstract

Embankment slope failures have recently occurred frequently due to the natural disasters. The typical regulation for embankment constructions is the degree of compaction on the top of embankment. However, there is no regulation for degree of compaction on the embankment slope. In this study, in order to develop a new system for evaluating the degree of compaction on the embankment slope, non-destructive testing method which measures ground stiffness was developed and performed in laboratory and in-situ. In this paper, in order to investigate the correlation between the dry density (degree of compaction) and ground stiffness obtained by the non-destructive testing method, the non-destructive tests were performed on specimens compacted with various moisture content and soil type conditions in laboratory. The validity of the estimated dry density (degree of compaction) on the embankment slope was confirmed by comparing to the results of RI method.
