| 摘要： | 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: (1) Increase the percent of RAP allowed in highway asphalt pavement projects from 15% to 30%; (2) Use crushed concrete for more project applications; (3) Replace wood products with more recycle-friendly products such as steel and plastic; (4) Replace raw materials with steel products made from recycled steel; (5) Increase use of rubber tire products in engineering applications; (6) Modify construction specifications and improve tracking to both increase and measure efforts; and (7) Present findings to engineers and DOT designers responsible for materials selection in project design. / Supplementary Notes: Sponsored by Colorado Dept. of Transportation, Denver.
