Field and Laboratory Characterization of Tire Derived Aggregate in Alberta

Tire Derived Aggregate (TDA) is made by shredding scrap tires into 50 to 300 mm pieces. This material is lightweight and has higher permeability and thermal resistivity than soil. Because of these properties, TDA has been successfully used as a fill material in various highway construction projects in the United States and other countries. Moreover, recycling discarded tires has economic and environmental benefits, such as eliminating the need to store waste tires in landfills. In order to evaluate the performance of TDA as fill material in cold climates, a largescale field and laboratory experiment was performed in Edmonton, Alberta. The field test embankment, which used nearly 7,000 tons of discarded tires, is an 80 m instrumented test road and contains four sections: 1) TDA from Passenger and Light Truck Tires (PLTT), 2) TDA from Off-The-Road truck tires (OTR), 3) TDA from PLTT mixed with soil and 4) native soil (control section). Large-scale, one-dimensional laboratory compression tests were also performed to characterize the compression behavior of different TDA material. The paper presents the test results and the findings of the field instrumentation. (A) For the covering abstract of this conference see ITRD record number 201310RT334E.
