NEW DELHI: In a first for the road sector, govt has used waste plastic as a wet mix with bitumen to lay a bituminous highway stretch, a move that is likely to reduce imports of the key construction material while addressing the growing problem of plastic waste.On Thursday, a pilot test section was laid on the main carriageway of NH-44 in Jhansi. Officials associated with the pilot said the technology has potential to reduce conventional bitumen consumption by around 4%, lowering demand for a material that India largely imports to meet domestic requirements. They added that the modified bitumen could cost around 20% less than conventional bitumen.The waste plastic wet-process technology for producing premium-quality Waste Plastic Modified Bitumen (W-PMB 76-10) has been developed by IIT (BHU), Varanasi, under a research programme funded by the ministry of road transport and highways. The performance of the pilot stretch will be monitored by IIT (BHU) to assess its long-term engineering performance and field suitability, officials said.India generates around 25,000 tonne of plastic waste every day. Until now, waste plastic has been used in road construction only as a dry mix with aggregates while laying the bituminous layer. The new method mixes processed waste plastic directly with bitumen before it is laid, making it the first such pilot on a national highway.Officials said the technology offers multiple benefits, including the value-added reuse of waste plastic through a scientifically controlled process and improved rut resistance of bituminous mixes under high ambient temperatures and heavy axle loads.Join conversationView All Comments →Share your thoughts in the commentsInsightfulAgreeDisagreeSkepticalConcerningPromisingWorth ReadingBig DevelopmentPost CommentBe respectful · TOI community guidelinesThe technology has also recently been granted a patent.
