Evaluation of Rigid Pavement Overlay Design Procedures
A review and evaluation of existing rigid pavement overlay design procedures, including the ARE procedure (DOT-FH-11-8544) resulted in a fully computerized rational method for the design of overlays for rigid pavements. The thickness of overlay is determined from the consideration of protecting the surface layer from fatigue failure while allowing lower layers (old pavement, bondbreaker layer) to fail during the design life. The progressive failure concept results in thinner overlays than would be derived from previous concepts of preventing further fatigue damage to the existing pavement. Stress analysis is done using elastic layer theory with edge and corner load adjustment factors developed using a plate on multilayer elastic solid foundation program, consequently program execution is very fast. The OAR procedure has been applied to several pavements in different parts of the U.S. with excellent correlation in performance prediction.
