Influence of Relative Density and Clay Fraction on Soils Collapse

Abstract

Most of the works conducted to investigate the parameters likely to govern the behavior of collapsible soils, have been dedicated to initial dry density, water content, degree of saturation and applied load. On the other hand, relatively few works have been oriented towards the study of the influence of clay fraction and relative density on the collapse of this type of soils. The experimental study, about reconstituted soils, presented in this paper, aims at highlighting the effect of relative density and clay fraction on the rate and magnitude of collapse.
