Abstract:The purpose of this study was to systematically evaluate the cost and performance of recycled materials in roadway construction applications. Specifications and guidelines for using recycled materials were developed in previous research efforts. Several non-hazardous recycled materials (NRMs) exhibited high potential for roadway construction applications during the earlier studies. Eight materials were selected for demonstration projects under the Federal Highway Administration Priority Technology Program. Demonstration projects were placed at several locations within the state of Texas. The eight materials selected were: Bottom ash, Compost, Crushed concrete, Glass cullet, Roofing shingles, Shredded brush, Spent blasting sand, and Tires. The demonstration projects afforded the Texas Department of Transportation an opportunity to field test specifications and guidelines for the NRMs. Evaluations for several of the demonstration projects included load tests, visual inspection and economic analysis. This report describes each demonstration project, presents available evaluations results, and compiles applicable material guidelines, specifications, and points of contact for each demonstration project.
