Green Facts

A considerable amount of tire-derived aggregate for civil engineering applications come from stockpile abatement projects.

Every cubic yard of tire-derived aggregate provides a beneficial end-use for 75 used passenger tires.

Tire Derived Aggregate

EPA-Approved for Civil Engineering Applications

Civil engineers rely on tire derived aggregate as a sustainable and less-expensive alternative to conventional materials, such as expanded shale or polystyrene insulation blocks, drainage aggregate, or even soil and clean fill.

Tire Derived Aggregate Works

  • 1/3 the weight of soil
  • Drains 10 times better than soil
  • Insulates 8 times better than stone
  • Costs less than sand and gravel

Liberty Tire Recycling produces tire derived aggregate for civil engineering projects that call for high-performance variables.

Subgrade Fill and Embankments

TDA is used to construct embankments on weak, compressible foundation soils due to its light weight and lower cost.

Backfill for Walls and Bridge Abutments

TDA is useful as backfill for walls and bridge abutments because its lighter weight reduces horizontal pressures and allows for construction of thinner, less expensive walls.

TDA also reduces problems with water and frost build up behind walls because tire shreds are free draining and provide good thermal insulation.

Subgrade Insulation for Roads

The high permeability of TDA allows water to drain from beneath roads, preventing damage to road surfaces. TDA can also prevent subgrade soils from freezing, which reduces excess water during thaw cycles.

Septic System Drain Fields

TDA replaces traditional stone backfill material, holding more water and transporting easier due to its light weight.

Alternative Daily Cover

TDA is used as alternative daily cover at landfills. Landfill operators use this material as a dust free alternative to dirt, clay and aggregate.

Drainage for New Landfill Cell Construction

TDA is used instead of aggregate to provide drainage for landfills.
