Design of Concrete Overlays Using Existing Methodologies - F24 DCO
(Free Publication) - Over the years, concrete overlay design procedures have been developed by a number of agencies, including the American Association of State Highwayand Transportation Officials (AASHTO),the National Cooperative Highway Research Program (NCHRP), the Portland Cement Association (PCA),the American Concrete Pavement Association (ACPA), and various state departments of transportation (DOTs).Each method addresses different types of concrete overlays and involves different inputs, software, strengths, and deficiencies. This technical summary provides an overview of the concrete overlay design process and identifies some of the more sensitive variables inherent with three different procedures: (1) the 1993 AASHTO Guide for Design of Pavement Structures (1993 AASHTO Guide), (2) the Mechanistic-Empirical Pavement Design Guide (MEPDG), and (3) the,ACPA method for bonded concrete overlays on asphalt (BCOA) pavements. The first method, the 1993 AASHTO Guide, is the procedure most commonly ,used today for concrete overlay thickness design. The MEPDG is currently being implemented and evaluated by numerous state DOTs and is therefore included here. Finally, the ACPA BCOA method is presented to address the unique behavior of thinner BCOA, which is not captured by the first two methods.
