Abstract: A series of laboratory tests were carried out to investigate the physico-mechanical properties of EPS beads-mixed lightweight soil which is made of sand and treated with cement. Results show that the compaction and moisture content of the treated soil have significant effects on its density and strength. There exist suitable compaction times and optimum moisture content. The effect of the moisture content during sample preparation on the stress-strain relationship was analyzed and linear relationship was obtained between the strength and cement content with fixed water-cement ratio.

Key words: lightweight soil, EPS, compaction, optimum moisture content, unconfined compression strength, stress-strain relationship
