The document discusses the use of plastic waste in road construction. It outlines the types of plastics used, including thermosets, elastomers, and thermoplastics. The basic process involves segregating, cleaning, shredding, and collecting plastic waste, which is then mixed with hot bitumen using wet or dry processes. Using plastic waste in road construction can increase the melting point of bitumen, strengthen roads, increase their lifespan, reduce costs, and help the environment by reusing plastic. However, there are also disadvantages like potential toxic leaching during construction or from the road over time. Overall, plastic roads could provide environmental and economic benefits for countries with warm, humid climates if the technology is implemented properly
