...S. S. AbdelSalam; S. A. Azzam Expanded polystyrene geofoam has long been used as a compressible lightweight alternative for soil backfills to reduce lateral pressure behind retaining walls. Uncertainty in material properties and lack of design parameters are the main constraints to using local...

...A. Ossa; M.P. Romo ABSTRACT: A series of uniaxial and triaxial compression tests was carried out in order to study micro- and macro-mechanical compressive behavior as well as some other mechanical properties of expanded polystyrene. Micromechanical behavior was analyzed by performing uniaxial...

...V.C. Xenaki; G.A. Athanasopoulos The results of laboratory direct shear tests conducted at the expanded polystyrene (EPS) geofoam-sand interface are presented in this paper. The sands used in the tests were composed of rounded to subangular particles with values of mean particle size ranging from...

...Y. Zou; C.J. Leo; J.C. Small The behavior of expanded polystyrene (EPS) geofoam used as subgrade and fill material under flexible pavement was investigated by carrying out a series of tests in a model pavement testing facility. In the experimental setup, pavement test sections that consisted...

...G.A. Athanasopoulos; P.C. Pelekis; V.C. Xenaki This paper presents the results of an experimental investigation of the dynamic properties of two expanded polystyrene (EPS) geofoam materials. Torsional resonant column tests and cyclic uniaxial tests were conducted on block-molded EPS geofoam...
