Abstract:In an effort to promote the use of increasing stockpiles of waste tires and a growing demand for adequate backfill material in highway construction, the New Mexico Department of Transportation (NMDOT) has embarked on a move to use compressed tire-bales as a means to reduce cost of construction and to recycle used tires which would otherwise occupy much larger space in landfills or be improperly disposed of. Compressing the tires into bales has prompted unique environmental, technical, and economic opportunities. This is due to the significant volume reduction obtained when using tire-bales [approximately 100 auto tires with a volume of 20 cu yd (15.3 cu m) can be compressed to 2 cu yd (1.53 cu m) blocks, i.e., a tenfold reduction in landfill space]. Lighter unit weight, 37 pcf dry (592 kg/cu m), results in lower earth pressure with lesser possibility for foundation failure. The objective of this project was to address the question, “Can tire-bales be used as a cost effective alternate fill material for erosion control and bank stabilization projects?”
