Dow joins project building roads with recycled LDPE Plastic waste for asphalt road building Indonesia, a country of nearly 263 million people and the fourth most populous in the world, has set a goal of reducing plastic waste in the ocean by 70 percent by 2025. As part of the project, 3.5 metric tons of recovered plastic were mixed into asphalt, which was used to create a mile-long stretch of test road in Depok city, West Java late last year. The road is being tested by the country’s National Center of Road and Bridge Construction. “The result of the two-month long project was a highly resistant plastics waste road that was more durable and stronger than typical roads,” according to the release. According to a Google translation of a government press release, the process involves shredding LDPE into pieces of 9.5 millimeters or less. Washing and drying is required to remove contaminants, including organic residue. The plastic is then stirred into hot aggregate for about 10 seconds, allowing it to melt and covers the aggregate surface. Finally, hot asphalt cement is stirred into it for 35 seconds. The resulting pavement is more resistant to deformation and fatigue-cracking than standard asphalt. resource-recycling.com
