Finite-Element Modeling of Crack Sealant Flexible Pavement

This paper documents the use of finite element analysis techniques to determine the failure mechanism in a crack sealant pavement under moving loads. The flexible pavement is modeled on a medium-strength subgrade. The stress-strain response of the medium soft clay is simulated using an elastic-plastic model. The three-dimensionality of the failure surface under actual wheel loads with wander requires that computationally intensive 3-D models are used. The finite element techniques employed are verified against available failure data of the laboratory testing samples. The paper discusses the advantages and limitations of the crack sealant models currently used in pavement analysis. In addition, the paper also discusses efficient finite element techniques that can be used for crack sealant pavement analysis to reduce the computational time without sacrificing accuracy.
