Reuse of waste plastic in road construction is a suitable solution for the disposal of waste in an eco friendly way and thus avoiding the pollution created by the plastics in the environment. Presently the waste plastics are either land filled or incinerated. Both the processes are non technical and it will affect the environment in near future. In this context since the project of plastic road laying avoids land filling and incineration of waste plastics, it is considered as an effective process for the disposal of waste plastics.

Plastic tar road has double strength, compared to ordinary bitumen road. It can withstand both heavy load and heavy traffic. It is not affected by rain or stagnated water. And hence no pot hole is formed. There is no rutting and raveling. The life of the road is not less than seven years and there is no need for maintenance expenditure. Performance studies of the plastic tar road were carried out as per Central Road Research Institute specification and the results are very good. It has been published by CPCB and NRRDA as monographs.

Major road laying is done by the government only, either by Panchayat, municipalities or by corporations. The NHAI is doing major road works in India. The technology can be adopted by the consumers. India has not less than 41 lakhs Kms of road network of which 66, 000 Kms are Highways and 24, 00, 000 Kms are rural roads, state highways etc. More than 50, 000 Kms of roads have been already laid by using this technology. Nearly 11 states have started implementing the technology.
