Tire-Derived Aggregate (TDA)
Tire-derived aggregate (TDA) is made from shredded scrap tires and is used in a wide range of construction projects. These uses include retaining wall backfill, lightweight embankment fill, landslide stabilization, vibration mitigation, and various landfill applications.
TDA is…
• Cost-effective: Less expensive than other lightweight fill materials.
• High-performing: Lightweight, free-draining characteristics help solve engineering problems.
• Environmentally friendly: TDA reduces need for mined resources such as pumice and gravel.
FAQ
• What is TDA?
TDA is a 100 percent recycled material made from waste tires shredded to a specific size unique to a wide range of public works projects and other civil engineering applications.
• Is TDA harmful to the environment?
Studies have shown that TDA has no harmful impact to the environment. However, the specifications, design and construction methods developed for TDA projects are all done in ways that assure that there will be minimal environmental impacts.
• Do you need special equipment to transport and place TDA?
TDA is transported by truck to a project in a 40-foot walking floor trailer which makes it easy to unload material. Once it is delivered to the site, TDA is then spread and compacted by standard earth working equipment.
• Why should you use TDA in construction projects?
The lightweight, free-draining and vibration dampening characteristics of TDA make it a cost-effective solution to a variety of civil engineering applications. It is also a viable reuse alternative to the 10 million waste tires currently being disposed of in landfills.
• What is TDA in civil engineering?
Tire derived aggregate (TDA) is used for a wide range of public works projects and other civil engineering applications. These include lightweight embankment fill, landslide repair/slope stabilization, various landfill applications, retaining wall backfill, vibration mitigation, and more.
