Discover the key to long-lasting, cost-effective concrete pavement repairs

Aging concrete pavements often present challenges, but there's a proven solution that delivers durability, cost savings and environmental benefits. Dowel Bar Retrofit (DBR) is transforming pavement preservation by restoring strength, smoothness and longevity to roadways. The benefits of DBR include:

• Restoring load transfer: DBR reinstates load transfer across joints and cracks by connecting adjacent slabs with dowel bars, preventing vertical movement and extending pavement life.

• Cost-effectiveness: Unlike asphalt overlays, DBR is only applied to the affected lane, reducing unnecessary costs while avoiding additional expenses like raising guide rails and overhead signs.

• Improving ride quality: A smoother roadway is achieved when DBR is combined with diamond grinding, eliminating faults and enhancing the driving experience.

• Environmentally friendly: DBR reduces material use, lowers fuel consumption and vehicle wear, and decreases heat island effects due to reflected light.

In addition, diamond grinding, when applied after DBR is installed, improves safety by enhancing friction. Researchers in Wisconsin determined the wet weather accident rate for diamond ground surfaces was nearly half of that for non-

ground pavement.

When properly constructed, DBR can last more than 20 years, protecting taxpayer investments by optimizing pavement performance and sustainability.
