Maharashtra government to use plastic wastes to build roads


Maharashtra government has decided to use plastic waste along with tar in a bid to improve the durability and longevity of asphalt roads and reduce soil pollution. In the beginning, municipal corporations with a population of over 5 lakh and municipal councils that have a population of over 2 lakh will be asked to include plastic waste for building roads in 50-km radius. For every 100 kg of tar used to build asphalt roads,
3 to 6 kg of plastic will be mixed in it, he said, adding materials like plastic carry bags, sacks, milk pouches, bin linings, cosmetic and detergent bottles, drinking water bottles, bottle caps, household articles will be used. Studies have revealed that plastics waste have great potential for use in bituminous construction as its addition in small doses, about 5-10 per cent by weight of bitumen, helps in substantially improving the Marshall stability, strength, fatigue life and other desirable properties of bituminous mix, leading to improved longevity and pavement performance. The benefits are – 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.
