Maharashtra Will Now Use Plastic Waste to Build Roads

Elaborating further, the official explained that for every 100Kg of tar for the asphalt roads, 3-6Kg of plastic will be used in the mix. Additionally, materials such plastic carry bags, sacks, milk pouches, bin linings, cosmetic and detergent bottles, drinking water bottles, bottle caps, household articles will be used.

The official clarified that the government has received assurance from the CSIR-Central Road Research Institute that these roads will not only offer improved quality, but will also be cheaper. Studies reveal that plastic waste offers considerable potential for use in bituminous construction. Addition of such waste in small doses, about 5-10 per cent by weight of bitumen, aids in substantial improvement of the Marshall stability, strength, fatigue life and other desirable properties of bituminous mix, leading to improved longevity and pavement performance.

Consequently, such roads will have higher resistance to deformation, water induced damages, increase durability, strength and ultimately dispose of plastic waste in a larger quantity to save pollution,consequently contributing to the construction of green roads.
