Research on the Interfacial Mechanics Behavior Characteristics of Asphalt Plug Expansion Joint Pavement
Publication: CICTP 2016
Abstract
The interface is the weakest part in the asphalt plug expansion joint pavement. ANSYS finite element software was adopted to analyze the interfacial stresses. The results show that the interfacial controlling indexes are the tensile stress and the shear stress. The cornering ratio and tire contact pressure have greater influence on the tensile stress and the shear stress of the interface. Some useful measures that are good for the interface include: choosing larger modulus of the expansion joint mixture, interface roughness processing, making the interfacial elevation difference smaller, preventing the vehicle starting or braking urgently on the expansion pavement, and preventing overloaded vehicles.
