“…Besides, some investigators formulated a model of the mechanistic behavior of EPS geofoam taking into account the characteristic properties of EPS geofoam (Wong and Leo, 2006;Chun et al, 2004). There are many advantages of using EPS geofoams as discussed in detail by Horvath (1995Horvath ( , 1996Horvath ( , 1997a and Stark et al (2004).…”

“…Both need to be investigated with respect to measuring and modeling their stress-strain characteristics so as to evaluate the field design and construction. To date, investigations regarding EPS blocks can be reached through many sources, for examples, field and laboratory measurements (Doskov 1997;Fang et al 2006), and modeling analyses (Chun et al 2004;Hazarika and Okuzono 2004;Wang et al 2006;Wong and Leo 2006;Hazarika 2006). There were also reports in the public domain about the measurements of soil-EPS-cement mixtures (Liu et al 2006;Zhu et al 2008)), whereas no implementation was reported on measuring and modeling the stress-strain behavior of soil-EPS beads mixtures.…”

A geofoam was produced by blending expanded polystyrene (EPS) beads and sands in proportions. The formed mixtures, known as EPS-sands, were 32-66% lighter than general earthfills (e.g., sand). Consolidated-drained (CD) triaxial compression tests were conducted on EPS-sand mixture specimens to observe their stress-strain characteristics, specifically, the stress-strain responses in relation to the EPS contents (0.5%, 1.5% and 2.5% by weight) used in the mixtures and confining pressures

“…This model was developed by the authors (Wong and Leo, 2006) based on experimental results from a series of standard "drained" triaxial tests. It initially adopted the Mohr-Coulomb yield function used widely in soil mechanics but upon further testing with a true triaxial apparatus , a Drucker-Prager type yield function was subsequently preferred.…”
