ADVANTAGES OF PLASTIC ROAD Use higher percentage of plastic waste. Reduce the need of bitumen by around 10%. Increase the strength and performance of the road. Reduce the cost to around Rs. 5000/Km. of single lane road. Generate jobs for rag pickers. Develop a technology, which is eco-friendly.

DISADVANTAGES OF PLASTIC ROADS 1. Cleaning process Toxics present in the co-mingled plastic waste would d start leaching. 2. During the road laying process But the presence of chlorine will definitely release noxious HCL gas.

3.After the road laying The components of the road, once it has been laid, are not inert. It is opined that the first rain will trigger leaching. As the plastics will merely form a sticky layer, (mechanical abrasion). once the road is started to be used will cause the release of fine polymer particles. When air-borne, these will cause a particulate problem.

CONCLUSION Plastic will increase the melting point of the bitumen use of the innovative technology not only strengthened the road construction but also increased the road life Help to improve the environment . plastic road would be a boon for India’s hot and extremely humid climate where durable and eco-friendly roads which will relive the earth from all type of plastic waste
