STRENGTH-DEFORMATIONAL CHARACTERISTICS OF EPS BEADS-MIXED LIGHTWEIGHT GEOMATERIAL SUBJECTED TO CYCLIC LOADINGS
A laboratory experimental study was carried out to investigate fundamental engineering properties of lightweight soil mixed with EPS (expanded polystyrene) beads and treated with portland cement. The soil used is a cohesive soil with a high natural moisture content and is often disposed as a surplus soil at a construction site. Both static and cyclic loading triaxial compression tests under the unconsolidated unconfined conditions were conducted for the mixture specimens compacted in laboratory. Effects of mixing rate, stress conditions, and numbers of replicates on the deformational behaviors were discussed. It was found from the results that these artificial soil mixtures with the compressive air-entrained beads showed different mechanical behavior from natural soils, the aggregates of which are composed of incompressible solid particles.
