Abstract

This article deals with experimental studies by lab tests for finding out a composite soil material with higher strength but lower unit weight. Soil from retreated site was broken, demoistured, crashed and then mixed with other materials including sand, cement as binder, shredded tires and water. Based on experimental procedure, a matrix for experiment design over percentage of ingredients was created and lab tests at different percentage (by weights) of ingredients were conducted in order to find out the reasonable proportion of ingredients which provided higher shear strength but lighter unit weight than that of in-situ soil. This composite soil material expects to contribute to effective material solution for mitigating soil instability.
