In the present experimental study, an attempt has been made to use the waste plastics in bituminous and cement concrete pavements. The type of plastic used in this study is of waste plastic which contains Water bottles , Tins , Plastic Buckets The waste plastic material is shredded into small pieces and is made to stick to heated aggregate to form a thin layer of plastic over the aggregate particles. Here the plastic was used as a modifier for aggregates (plastic coated aggregates) and bitumen (polymer modified bitumen). Engineering properties for modified and unmodified materials (aggregates, bitumen) were conducted and compared. The plastic is used in various percentages and performance tests were conducted such as water absorption & Specific gravity test , impact test , abrasion test , crushing value test for bituminous concrete mix pavements. A study has been conducted on unmodified aggregates using these plastic coated aggregates, and compressive strength was found out. The test results showed better performance values than unmodified materials for bituminous concrete.
