The Ready Mixed Concrete (RMC) Research & Education Foundation today released a new tool that will assist designers with designing concrete overlays for existing asphalt parking lots and will educate contractors on best practices for constructing them. The "Guide for Concrete Overlays of Asphalt Parking Lots" was prepared by the National Concrete Pavement Technology Center (CP Tech Center) with its development including review and input from a Technical Advisory Committee (TAC) comprised of the most experienced concrete overlay designers and contractors in the country. The guide, modeled after another pavement guide developed at the CP Tech Center, includes information and guidance in areas such as assessing the integrity of the existing pavement; selecting project candidates; pavement design principles and design life; managing parking lot drainage; and dealing with entry evaluations of adjacent buildings. The guide also incorporates aspects of ACI 330 "Guide for Design and Construction of Concrete Parking Lots".

"Today's release is the latest in a variety of tools developed through Foundation support that give industry professionals practical resources that they can utilize immediately," said Foundation Chairman Michael Harlan. Offered Foundation Executive Director Julie Garbini "The CP Tech Center at Iowa State has a terrific track record for the development of technical content like this guide so it was a natural partnership to work together on this project."

The "Guide for Concrete Overlays of Asphalt Parking Lots" is available for download from the Foundation's website and hardcopies are available by request. The guide will also be featured on a new Foundation "Tools & Resources" deliverables CD slated for release in early 2013. The Vision of the RMC Research & Education Foundation is to support research and educational programs that will increase professionalism, quality, and sustainability in the concrete industry.
