WASHINGTON-The Scrap Tire Management Council is helping the American Society of Testing and Materials develop guidelines for the use of scrap tires in civil engineering projects. Working with the ASTM Committee D34.15 on Construction and Other Secondary Applications of Recovered Materials, the STMC will gather information on civil engineering applications for tires ``from as many existing sources as possible,'' said STMC Executive Director Michael Blumenthal.
A final report derived from this work will be incorporated into the Committee D34.15 standard for recovered materials in construction and civil engineering. The report will take about 18 months to complete, according to Blumenthal.
The boom in scrap tire use in road construction, landfill operations, soil modification and other structural applications has made ASTM guidelines necessary. In 1990, the STMC noted, scrap tires were virtually unknown in civil engineering. By the end of 1993, approximately 5 million tires had been used in civil engineering projects, and industry sources estimate that number could exceed 15 million by 1995.
Technical data is now available on scrap tires in civil engineering, but no one until now has compiled them. Meeting with ASTM committee members in Montreal last month, Blumenthal volunteered to coordinate that effort.
The STMC will spend several weeks gathering information to answer specific committee questions, including the scope of scrap tire use in civil engineering, available reference documents and the determination of scrap tire characteristics. It then will broaden its inquiry to experts in industry, academia and state transportation departments.
