Abstract: Road infrastructure in India is developing at a very fast rate. A good pavement provides safe, comfortable and economical movement of traffic. The road thickness depends on various geotechnical properties of subgrade soil and traffic intensity. The pavement construction is becoming costlier because of very high cost of construction materials and transportation cost of such materials from long distances. The growing concern over environmental degradation due to borrowing of large quantity of soil and aggregates for construction of pavement has made the search for new techniques of stabilization. The subgrade soil should have high Maximum dry density (MDD) and low Optimum moisture content (OMC) so that it can take up the load of the overlying layers and the traffic. The high MDD and corresponding OMC can be achieved by stabilizing the soil using suitable stabilizer. In the present work the effect of using Nano Polymer called SoilTech MK III as a stabilizer to improve the properties of Black Cotton soil collected from Ranibennur region, Karnataka, India were determined. The laboratory experiments were conducted on the samples of BC soil and BC soil with stabilizer for Compaction test, UCS (Unconfined Compression Strength) and CBR (California Bearing Ratio) tests. Various samples were prepared by taking soil with different percentage of SoilTech MK III Polymer (0.2%, 0.4%, 0.6%, 0.8% and 1.0%). The comparison of the results with and without the use of SoilTech MK III has been done. All test were conducted as per IS 2720 standards.
