Tire Derived Aggregate (TDA) has properties that may help road supervisors, public works directors, and contractors save money while solving difficult problems. It is lightweight, free-draining, has low earth pressure (50% lower at base of 16 ft. wall) and is a good thermal insulator (8 times better than gravel or soil). TDA is durable, compressible, conserves natural aggregate resources, has good vibration dampening properties, and may be the cheapest solution for your road repair and maintenance jobs.
Rubberized Asphalt information TO BE ADDED SOON.
This course covers the benefits of using TDA in road construction and maintenance for local transportation agencies. Sample local TDA applications include: road construction, landfill projects, foundation backfill, underground stormwater control reservoirs, and external heat pump field insulating media.

Panel of Instructors:Dana N. Humphrey is Dean of Engineering at the University of Maine. He joined the University of Maine in 1986 after receiving his PhD in Civil Engineering from Purdue University. His research in using tire derived aggregate as lightweight fill, retaining wall back-fill, thermal insulation, drainage layers for landfills, and vibration damping layers beneath rail lines has received international attention with projects in the US, Canada, and Australia. he received the Governor's Special Teamwork Award for his part in the tire derived aggregate fill constructed for the Portland Jetport Interchange.
This course is an elective in the Roads Scholar I course track.
