| 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 | ||
