Indonesia’s Chandra Asri Petrochemical plans to work with the government to test the effectiveness of plastic-mixed asphalt.
In the early stage, Chandra Asri will use three tonness of plastic waste-asphalt mix to pave around 6.3km or roads around the its own plant, said Edi Rivai, general manager of technical services and production.
Rivai said the plastic-asphalt mix with around 6% plastic is usually around 30-40% more durable than pure asphalt.
The use of plastic-mix asphalt has been increasingly popular in Asia. In later 2015, parts of India legislated its use in hot-mix asphalt as part of a solution to decrease landfill. Road construction firms are required to incorporate waste plastic within hot mix when building bitumen roads within 50km of any city with a population of 500,000 or more. The Indian government hopes to reduce construction costs for road builders.
