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.
The Road to Sustainability
Rubberized asphalt is a high-performance alternative to traditional paving material. As a mix of asphalt and recycled rubber derived from scrap tires, rubberized asphalt is longer lasting, safer, less costly, and friendlier to the environment.
Resists cracking and rutting.
Cracks in asphalt are caused by vertical or horizontal movements beneath the overlay as a result of traffic loads, temperature fluctuations, and shifting earth. Rubberized asphalt reduces the occurrence of cracking with superior elasticity. Rubberized asphalt is also stiffer than conventional paving, which resists rutting and increases pavement life.
Improves skid resistance. Decreases splash and spray.
The safety of rubberized asphalt is greatly improved as a result of several unique attributes. Pavements made from rubberized asphalt exhibit greater skid resistance, and decreased splash and spray in wet conditions.
Decreases maintenance costs. Requires no additional capital investment.
In use for more than 40 years, rubberized asphalt is laid using the same equipment as traditional asphalt in most cases and the longer lasting properties reduce long-term maintenance costs. Plus, utilizing recycled rubber derived from scrap tires provides a reliable and consistent supply of material.
Rides quieter. Reduces stockpiles of scrap tires.
Noise pollution on highways and interstates continues to increase as traffic levels increase. However, rubberized asphalt is proven to reduce noise levels by upwards of 5 decibels. And rubberized asphalt provides an outlet for between 500 and 2,000 scrap tires per lane mile of pavement. So, for a 1-mile section of a four-lane highway, between 2,000 and 8,000 tires are creating a longer-lasting, safer, and more cost-effective roadway.
