Longitudinal reinforcement is the key technique for the construction of CRCP, however, an improper longitudinal reinforcement could limit the popularization and application of CRCP. This paper mainly focuses on the structure characteristics and the flaws of existing studies of CRCP and CRC+ AC composite pavement, longitudinal reinforcement method in current specifications is analyzed, using heat transfer theory and finite element method, temperature effect of asphalt concrete layer is researched, the influence of temperature effect on longitud...
