Abstract

Now-a-days disposal of different wastes materials produced from different industries is a great
problem. These materials pose environmental pollution in the nearby locality. Their potential for
use in the construction of highways suggests that valuable benefits in terms of economic and
environmental gains are possible. Two types of wastes materials, rice husk and sawdust were used
to improve the properties of the clayey subgrade soil. A procedure was adopted to quantify the
beneficial effect of subgrade soils stabilization benefits which base on the extension of pavement
service life and reduction in the base course thickness. Results show that both types of wastes
materials helps in great improvement of soil properties as California bearing ratio and unconfined
compressive strength to use in the construction of highways
