New Whitetopping Design Procedure Available
As asphalt prices have steadily increased, cities, counties and DOTs around the country have watched the buying power of their dollar dwindle as they attempt to keep up with a traditional asphalt mill and overlay program; and the demand for alternatives to asphalt overlays has drastically increased. Thanks to an FHWA pooled fund study, TPF 5-165, a rational design procedure for thin and ultra-thin concrete overlays of existing asphalt pavements is now available to help address that demand.
Dr. Julie Vandenbossche of the University of Pittsburgh, Swanson School of Engineering, developed a user-friendly, web-based program for the Bonded Concrete Overlays of Asphalt Mechanistic-Empirical (BCOA-ME) design procedure which guides the user through a handful of inputs to generate a final overlay thickness. This online program will always be up-to-date.
We encourage you to use the following link to review and start using the new Bonded Concrete Overlays of Asphalt Mechanistic-Empirical design procedure (BCOA-ME) today.
Guide to Concrete Overlays of Asphalt Parking Lots available
The CP Tech Center at Iowa State has published a new guide about selecting, designing, and constructing successful concrete overlays on existing asphalt parking lot pavements that serve multifamily residential, public, or commercial buildings. Download it.
StreetPave software use allowed by MnDOT
City, county and consultant engineers working on State Aid and Federal concrete pavement projects can choose to use the ACPA StreetPave software for jointed concrete pavement design. Download the Technical Memo. Learn how to get StreetPave12 on our Design Guide page.
