Effects of Cushion on the Induced Earth Pressure by Roller Compaction
Abstract The high earth pressure induced by dynamic loading frequently results in cracks in the culvert walls. In this study, expanded polystyrene (EPS) panel as a cushion material is applied on the culvert walls in backfill areas to reduce the compaction-induced dynamic earth pressure as well as to improve the characteristics of compacted soils. The result of numerical analysis shows that a cushion material with low elastic modulus and high damping ratio can effectively reduce the dynamic earth pressure. Field tests are also performed to validate the performance of the EPS panel. It is found that the EPS panel successfully reduces the dynamic earth pressure acting on the culvert wall.
