Waste plastic has emerged as a global environmental crisis, with plastic debris adding to landfills and contaminating both land and aquatic environments with macro and micro plastics. Dry-process recycling of waste plastic into asphalt allows higher recycling amounts to be pursued, and greatly expands the number of contractors that can readily gear up for pilot projects and if successful, routine production. Because of the head start in waste plastic research with an ongoing project with Dow, this project starts with a comprehensive field demonstration project in the spring/summer of 2021, followed by subsequent lab testing, additional field demonstration projects, and long-term monitoring of field projects. A test section utilizing ground tire rubber (GTR) will be part of the 2021 project in Columbia. |
