Innovative mixes combine shredded HDPE, LDPE, PET with bitumen to construct roads. This method reduces landfill waste and repurposes unrecyclable plastics.
Studies show plastic‑modified roads resist water damage, rutting, and thermal stress. India’s early adoption in 2002 delivered durable surfaces across over 1,000 km.
Trials in India, West Bengal, Singapore, Thailand, UK, USA report reduced bitumen use (8–10%), lower carbon footprint, improved lifespan, and lower maintenance costs.
Concerns remain about microplastic release, toxic emissions, material recyclability, and long‑term environmental impact. Experts stress need for standardization, monitoring, and further research.
