Development of strength model of lateritic soil-cement

Abstract

Since the shortage of crushed rock as base course in some regions of Thailand, the improvement of the lateritic soil-cement as pavement base course has been evaluated. Soil cement improvement has been used for many years because of the significant improvement in soil properties. The objective of the research effort is to investigate performance of Lateritic soil cement mixtures using experimental study. The experimental results in terms of unconfined compressive strength and elasticity modulus were improved significantly as the cement content is increased. The multiple regression models based on cement content and curing time parameters were proposed to predict the unconfined strength (UCS) and elastic modulus of Lateritic soil-cement. The proposed prediction models providing good correlations with the experimental data are presented in this study.
