St. Louis Engineering Firm Takes Lead in Concrete Overlays of Asphalt Parking Lots

During a recent trip to St. Louis, NRMCA Vice President, National Resources, Jon Hansen was shown a large number of parking lot projects that are concrete overlays of the existing asphalt. The projects included schools, a church and a recreational facility. There were multiple designers and contractors on the projects, but the consistent quality of each project is very evident. The joint promotion effort of Evan Bolesta of the Concrete Council of Saint Louis and Ken Liescheidt with the Missouri/Kansas ACPA has resulted in the majority of the local success.

At a meeting during the trip, Hansen met Jeff Moon with Bax Engineering, a civil engineering firm that has taken a leadership role in the design of concrete overlays of asphalt. During the discussion, Moon told Hansen that much of the specifications they use for these projects was developed using the Guide to Concrete Overlays of Asphalt Parking Lots, an RMC Research & Education Foundation-funded publication written by the National Concrete Pavement Technology Center. Moon also stated that concrete overlays are featured on the Bax Engineering Web site as one of the firm’s specialties and to build awareness of the process.
