Today, every vital sector of the economy starting from agriculture to packaging, automobile, building
construction, communication or InfoTech has been virtually revolutionized by the applications of plastics. In recent
years, applications of plastic wastes have been considered in road construction with great interest in many developing
countries. The use of these materials in road making is based on technical, economic, and ecological criteria. The lack of
traditional road materials and the protection of the environment make it imperative to investigate the possible use of
these materials carefully India has a large network of metro cities located in different parts of the country and many
more are planned for the near future. Several million metric tons plastic wastes are produced every year in India.
Traditionally soil, stone aggregates, sand, bitumen cement etc. are used for road construction. Natural materials being
exhaustible in nature, its quantity is declining gradually. Also, cost of extracting good quality of natural material is
increasing. Concerned about this, the scientists are looking for alternative materials for highway construction, and
plastic wastes product is one such category
