An Experimental Study on Renolith Treated Black Cotton Soil for Subgrade Pavements

There are many sub-grade problems especially when the sub-grade is of clayey soils. The main reason is due to the presence of enormous quantity of montmorillonite mineral. Thus in the present study an attempt has been made to bring an alternative solution to enhance the properties of clayey soil available locally by conducting laboratory experiments on the soil samples treated with polymer chemical Renolith. Renolith is one Renolith is a polymer chemical which is a water soluble white milky viscous liquid. It is non toxic and eco friendly polymer chemical which when mixed with soil, cement and road construction material forms a sturdy polymer surface that facilitates additional strength, flexibility and permeability to the pavement. The polymer chemical is used along with cement to enhance its efficiency with the clay particles of the soil. The soil is treated with different quantities of Renolith and cement. The various laboratory tests such as Liquid Limit, Differential Free Swell Index, Standard Proctor Compaction test and California Bearing Ratio test are conducted to examine the improvement in the properties of the soil.
