The Ready Mixed Concrete Research & Education Foundation has released a new tool that will assist 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 with review and input from a Technical Advisory Committee. The guide 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 330R, Guide for Design and Construction of Concrete Parking Lots.
