WASTE MATERIALS RECYCLING IN HIGHWAYS CONSTRUCTION

Now-a-days disposal of different wastes materials produced from agricultural and industrial residuals is a great problem. These materials pose environmental pollution in the nearby locality. As a result, there has been a trend towards recycling the waste materials into a highway construction system. Valuable benefits in terms of economic and environmental gains are possible. Two types of wastes materials, rice husk and sawdust were used t o 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.
