This paper reviews the research progress and the development trend of the smart pavement in the context of the autonomous driving. Three key technologies of the smart pavement are identified to realize the cooperative interaction with the AVs, the self-navigation technology provides the location information for the AVs by embedding the vehicle navigation signs in the pavement; the self-sensing technology can recommend the safe speed for the AVs and reduce the traffic accidents through the perception and the analysis of the road weather information and the traffic flow information; and the self-charging technology involves problems of the high electromagnetic resistance and the thermal conductivity pavement materials and the new composite pavement structures, related with the feasibility of the charging system. Three advanced construction technologies of prefabricated pavement technology are discussed, the BIM and the 3D printing are used by the smart pavement to ensure the service life of the refined construction and the embedded components. Finally, it is pointed out that in addition to the key technical problems, the promotion of the intelligent pavement also faces social, economic, legal and environmental non-technical problems.
