Abstract:The concept and framework of smart pavement are interpreted and proposed in this paper. The vision of transportation system is clarified as “zero casualties, zero delay, zero maintenance, zero emission and zero fail”. Towards the vision, the definition of smart pavement is given based on the elements of smart organism. Smart pavement is defined as an infrastructure that composed of advanced structure and material, monitoring network, data center, communication network and energy supply system, which has the ability of selfmonitoring, automatic analyzing, selfadaptation, information interacting and continue energy supplying. Based on the definition, the function characteristics including basic performance, smart ability, information service, sustainability are proposed. Then a 5 levels system is developed for the smart ability of smart pavement. This paper constructs the framework of Smart pavement from five aspects: physical elements, information direction, energy way, spatial location and P2X (pavement to X) service. The concept and framework can be used as the guide for smart pavement research and application.
