ABSTRACT
This study comprehensively evaluates the service performance of asphalt pavement and establishes an intelligent sensing based asphalt pavement service performance indicator system. The principles for establishing a monitoring index system for asphalt pavement were proposed. A monitoring index system has been established for permanent deformation, fatigue performance, low-temperature performance, and water stability of asphalt pavement. Permanent deformation is measured by the internal shear stress and shear strength of the asphalt layer; Fatigue performance is measured by stiffness modulus and dynamic modulus; Low temperature performance is measured by creep stiffness, fracture strain, and crack index. The main monitoring indicators for water stability are loose road surfaces and potholes. The service performance index system of asphalt pavement can comprehensively reflect the establishment status of asphalt pavement, effectively supporting the application of intelligent sensing system.
