Characteristics of EPS Materials and the Application in Road and Bridge Projects

摘要

EPS (Expanded Polystyrene) materials have the features of super light, water resistance, anti-ageing, corrosion resistance and well supporting itself. They are now widely used in civil engineering because of their unique features for its unique characteristics. This paper introduces the properties of EPS and the application of EPS in the road and bridge engineering. The correlation analysis showed that The pressure on the foundation can be greatly reduced by the EPS filling embankment in soft foundation, and the settlement and displacement of the EPS embankment are small and its stability is good. The application of EPS in the embankment of a bridge can solve the bumping problems due to differential settlements of road and bridge. EPS's application can reduce differential settlement in the embankment splicing and strengthen intensity in the embankment splicing, which making the new and old expressway as a union in the road-widening project.
