A Direct Shear Investigation on the Determination of the Shearing Resistance of Reinforced Soil with Waste Rubber

Abstract

Disposal of Waste Rubber has an enormous impact on improvement of Environmental performance all over the World. Algeria is concerned with the problem of waste Rubber to achieve the maximum possible benefits in both of Economic and Environmental fields by solving this Issue. In recent years, there has been increasing interest in the use of recycled tires in civil engineering applications, particularly in soil improvement studies as a lightweight backfill. The aim of this Study is to get a clear vision of the effect of using Rubber grains on the shear strength behavior of Chlef River’s sand. A series of direct shear test have been prepared in laboratory using mixtures of sand and rubber grains mixed randomly contained 5, 10, 15, 20 and 30% rubber grains by weight. The direct tests conducted with two relative densities of Dr = 55 and 95% and all the samples were tested under confining pressure of 100 kPa. The results show that the rubber grain content influences the shear strength characteristics of sand-rubber grain mixtures.
