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."
The "Guide for Concrete Overlays of Asphalt Parking Lots" is available for download from the Foundation's website at www.rmc-foundation.org 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.
