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, 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. 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 cubic yards can be
compressed to 2 cubic yard blocks, i.e. a tenfold reduction in landfill space). Lighter unit weight, (37 pcf
dry), results in lower earth pressure with lesser possibility for foundation failure.
The objective of this project is to address the question, “Can tire-bales be used as a cost effective alternate
fill material for erosion control and bank stabilization projects?”
