|The performance life of asphalt surfaced parking lots can be extended by placing a bonded concrete layer on top of the existing asphalt. This technique has been used for many years for highway, street and parking lot pavements but still engineers and owners are unfamiliar with the process. This session will cover the publication entitled the Guide to Concrete Overlays of Asphalt Parking Lots and demonstrate the steps necessary to properly design and construct a concrete overlay. Learning ObjectivesLearn how to evaluate and assess an existing asphalt parking lot for a concrete overlay. Understand how to determine the thickness of concrete required to be placed over the asphalt.Learn the various construction techniques and how to determine the proper joint spacing.Discover which details of the specification criteria are especially important for these projects.
