Symposium Proceedings: Recovery and Effective Reuse of Discarded Materials and By-Products for Construction of Highway Facilities

The highway construction industry has a long history of using discarded materials and by-products in the construction of highway facilities. From asphalt cement to fly-ash, the industry has found ways to use waste materials to enhance the quality and durability of the highway infrastructure. In an attempt to mesh society's need for safe and economical disposal of discarded materials and by-products with the highway community's need for better and more cost-effective construction materials, Congress passed Section 1038 of the Intermodal Surface Transportation Efficiency Act of 1991, commonly known as ISTEA. Section 1038(b) of ISTEA requires the Secretary of Transportation and Environment Protection Agency (EPA) Administrator to conduct studies to determine the economic savings, technical performance qualities, threats to human health and the environment, and environmental benefits of using recycled material in highway devices, appurtenances, and highway projects. On October 19-22, 1993, the Federal Highway Administration and the EPA cosponsored a symposium entitled "Recovery and Effective Reuse of Discarded Materials and By-Products for Construction of Highway Facilities." The symposium addressed the requirements of Section 1038 and provided a forum for the dissemination of information on new and innovative uses for waste materials and by-products in highway construction. The agenda for the symposium (and this report on the proceedings) was broken into seven main categories: Welcome, Overview, and Keynote Address; Overview of Recycling in Highway Construction and Discarded Building Materials; Managing Mining and Mineral By-Products; Management of Industrial By-Products; Recycling Domestic and Household Waste; and Panel Discussion of Issues. This report also contains a summary of the questions that were addressed (after each session) to provide the reader with an example of the attendees' concerns. A list of attendees is also included at the end of the proceedings document. This document contains the technical papers that were presented at the symposium as well as papers that (although time precluded their formal presentation at the symposium) were found to be worthy of publication.
