The Lucknow Development Authority (LDA) is constructing a road using plastic waste for the first time ever. The road is constructed from Gomti Nagar Police Station to Indian Institute of Management (IIM) under a pilot project by LDA in Lucknow, Uttar Pradesh. The LDA has followed guidelines of the Central Road Research Institute (CRRI) in road construction.
The research showed mixing plastic waste increases the durability of the roads by 40-50%. These roads will be more durable and will stay in good condition for a longer time. Around 8-10% of plastic waste is being mixed in coal tar.
The initiative was inspired after the success of roads in many foreign countries. In India too, many civic bodies have started road construct using plastic waste in an environmental-friendly experiment. The LDA plans to conduct more research on this road experiment in the next two years to know if there can be some improvement.
The implementation of plastics in roads has opened a new option for recycling post-consumer plastics. The US, the UK, Australia, Indonesia, India, and many other countries have used technology which can incorporate plastic waste into an asphalt mix. Plastic composite roads, however, have existed and demonstrate characteristics superior to regular asphalt concrete roads; specifically, they show better wear resistance.
Central Road Research Institute (CRRI):
CRRI was established in 1952. The CRRI is located in New Delhi. It is a constituent laboratory of India’s Council of Scientific and Industrial Research. It conducts research and development in the areas of design, construction, maintenance, and management of roads and airport runways. It also works in the area of traffic and surface transportation planning.
