• Description:
  The Colorado Department of Transportation (CDOT) secured a Resource Conservation Grant provided by the U.S. EPA to determine a strategy to improve recycling on highway projects and reduce waste in landfills. The project focused primarily on five high-tonnage materials: asphalt, concrete, metal, wood, and tires. These materials can be reused, recycled, and replaced on highway projects in cost-effective ways. Recommendations include: • Increase the percent of RAP allowed in highway asphalt pavement projects from 15% to 30%; • Use crushed concrete for more project applications; • Replace wood products with more recycle-friendly products such as steel and plastic; • Replace raw materials with steel products made from recycled steel; • Increase use of rubber tire products in engineering applications; • Modify construction specifications and improve tracking to both increase and measure efforts; and • Present findings to engineers and DOT designers responsible for materials selection in project design.
