Abstract
Tire derived aggregate (TDA) is an engineered product made by cutting scrap tires into 1- to 12-inch pieces. In
2004, 60 million tires were used as TDA making it one of the fastest growing uses of scrap tires. What’s fuelling this
growth? TDA provides many solutions to transportation challenges. It is lightweight (50 pcf), produces low lateral
pressures on walls (as little as 1/2 of soil), is a good thermal insulator (8 times better than soil), has a high
permeability (> 1 cm/s for many applications), and absorbs vibrations. Just as importantly, TDA’s special properties
can greatly reduce construction costs. TDA has been economically used for a wide range of applications. It has
been used as lightweight fill for highway embankments in 13 states. The low unit weight, and resulting low earth
pressure, combined with high permeability makes TDA an attractive backfill for retaining walls, bridge abutments,
and sheet-pile walls. Maine, Louisiana, Pennsylvania, and California have TDA retaining wall projects. The
permeability of TDA has led to significant use as edge drains. TDA has been used as a vibration-damping layer
beneath rail lines to reduce the effect of ground born vibrations on the occupants of nearby buildings. This
technology was used for ½-mile of track for a recently completed commuter rail line in San Jose, California. A
recently completed summary of environmental effects shows that TDA has negligible effect on water quality.
About the Speaker
Dana N. Humphrey
Interim Dean of Engineering
Malcolm G. Long Professor of Civil Engineering
University of Maine
Dana N. Humphrey is Interim Dean of Engineering at the University of Maine. He joined the University of Maine in
1986 after receiving his Ph.D. in Civil Engineering (Geotechnical) from Purdue University. His research in using tire
derived aggregate as lightweight fill, retaining wall backfill, thermal insulation, drainage layers for landfills, and
vibration-damping layers beneath rail lines has received international attention. In addition, Dr. Humphrey has had
major design responsibility for over 20 full-scale projects using tire derived aggregate and has authored 50 papers
and technical reports in this area. Dr. Humphrey is the primary author of ASTM D6270-98, “Standard Practice for
Civil Engineering Applications of Scrap Tires”. In addition, he has conducted three research projects investigating
the effects of tire shreds on groundwater quality. He is currently a consultant to government agencies, including the
California Integrated Waste Management Board, and private companies in the United States and Canada on civil
engineering applications of scrap tires. The International Tire and Rubber Association honored him with their 1997
Friend of the Industry Award. Maine’s governor awarded him the 1997 Special Teamwork Award for his part in the
tire derived aggregate fill constructed for the new Portland Jetport Interchange.
