The National Concrete Pavement Technology Center (CP Tech Center), a partner organization of ISCP, has released a new guide titled Concrete Overlay Repair and Replacement Strategies, addressing one of the final questions in concrete overlay management: how to handle repairs and end-of-life strategies effectively. As concrete overlays continue to gain popularity as a cost-effective pavement management solution, the guide provides essential strategies to help agencies extend the lifespan of their investments.
Authored by Gerald Voigt of Square One Pavement Consulting LLC, the guide offers a range of preservation and repair solutions tailored to common concrete overlay distresses. It details a variety of repair techniques, including pressure relief cuts, full-depth and partial-depth repairs, dowel bar retrofits, cross-stitching, and diamond grinding. Additionally, it discusses end-of-life strategies such as overlay replacement, partial and full inlays, and complete reconstruction, ensuring that agencies can make informed decisions based on their specific pavement conditions.
The guide emphasizes that no single solution applies universally to concrete overlay repair. Instead, it provides detailed guidance on distress identification, appropriate repair or preservation methods, and how these options affect the long-term performance of the pavement. Covering four main types of concrete overlays—bonded and unbonded overlays on asphalt and concrete—the guide equips engineers and contractors with the necessary tools to assess and address overlay deterioration effectively.
Funded as part of the Federal Highway Administration’s cooperative agreement Advancing Concrete Pavement Technology Solutions, this guide completes a comprehensive suite of technology transfer resources on concrete overlays available from the CP Tech Center. Engineers, contractors, and transportation agencies can access this guide and other related publications on the CP Tech Center’s website, ensuring they have the knowledge to maintain and preserve concrete overlays throughout their entire life cycle.
