Structural Characterization of Asphalt Overlays Placed on Heavily Trafficked Concrete Pavements
The report presents the results of a study examining the structural characterization of mixes placed as overlays on portland cement concrete Interstate pavements and the problems associated with rapid deformation failure of these mixes. The study indicates that these mixes are subject to a more severe stress state than a mixture placed on a traditional flexible pavement structure. The differences arise from the pavement structure and construction practice differences between the two types of construction. An examination of failure theory indicates that the octahedral shear stress theory of failure can explain the development of premature deformation failure in these mixes. The results of a statewide survey of overlayed Interstate pavements clearly indicates that the gradation of the mixture and construction variables have the biggest impact on the structural integrity of the mixture in lowering the ability to resist premature deformation. A laboratory program demonstrates the influence of gradation on structural properties of the mixture that can be related to the susceptibility of a mixture to premature deformation.
