Study on Behavior of Plastic Road—A Case Study

Plastic roads are laid across various parts of India due to their higher durability than bituminous roads. This case study primarily analyzes the plastic wastes in and near the selected study location; further, the design of plastic roads with modified bitumen is carried out, and the performance is compared with typical bitumen roads. The needs for designing plastic roads are to utilize plastic wastes from nearby locations without emission of toxic gases, increase the durability, minimize the maintenance cost of roads nearly to nil, and save the bitumen for laying the roads. This study includes procuring data regarding plastic waste, soil testing, traffic analysis, and pavement design. Pavement design includes the design of the base course, sub-base, and wearing course of the road. After designing, the deflection and stress pattern of plastic roads and normal bitumen roads is analyzed using KENPAVE software. Damage analysis is performed to find the lifespan of roads. A comparison of the behavior of plastic roads and the bituminous road is carried out based on the damage analysis.
