To enhance the properties of soil and reduce the cost of project, polymer was used as an additive for the improvement of a base material of the road work. Polyacrylamide (PAM) is one such polymer which have many advantages including reduction in permeability, an increase in durability and its provision of strength characteristics. It is very cheap and easily available. In the progress of work, 0.02% of polyacrylamide (PAM) polymer is added to the dry weight of black cotton soil. Soil has been collected from Lonara Village (15 km away for Nagpur city). Various index & engineering properties have been tested on treated and untreated samples. The result obtained on both the samples are compared and we get appreciable enhancement in the property of soil. Our main objective is to test the soil on two parameters i.e. improvement in strength and improvement in CBR value of the soil sample. These type of improvement have allow to use the polymer in road construction work.
