Tire-Derived Aggregate

 

 

 

Tire-derived aggregate (TDA) is made of shredded end-of-life tires and used as a sustainable and lightweight alternative to natural aggregate. The shreds can vary in size and are used as drain-fill material, backfill, permeable fill for infrastructure, and insulation. Organizations choose TDA for a variety of reasons—it is lightweight, offers improved drainage, achieves a higher insulation value and absorbs vibrations better than conventional sand, gravel and rock. Plus, customers are using existing material rather than mining for virgin aggregate.

Tire-derived aggregate ideal for these projects:

• Drainage material for landfills, septic systems and road bases

• Backfill for roads, embankments and retaining walls

• Bridge abutments

• Vibration control along railroad tracks and light rail systems

• Foundation drains and backfill

• Gas well and water well fill
