Resources on Concrete Overlays
Concrete overlays offer cost-effective, versatile, short- and long-term solutions for the full range of concrete, asphalt, and composite pavement needs. In addition, they contribute to more sustainable construction practices by preserving pavement service for several decades beyond the original design life.
The National CP Tech Center has developed a comprehensive guide to concrete overlays and a field application program to help state DOTs successfully construct concrete overlays. A guide for existing concrete overlay design methodology is under development.
Following are some of the resources developed by the National CP Tech Center and its partners on concrete overlays.
