CMU in collaboration with the Department of High Ways, Department of Rural High Way, Group of DOW Chemical Co. Ltd. Thailand and the Siam Cement Group Co. Ltd. have joined together in the Development of Using Waste Plastic for making concrete asphalt roads.

This project has started in 2017 and waste plastic has been used with asphalt concrete to build a road that has passed various tests A 1 km long road that is 6 meters wide has been built that has used 3 tons of plastic waste or approximately 900,000 plastic bags.
