In order to promote the high level development of China’s road engineering assemblyconstruction, innovative R & D design and application, combined with engineering practice, theimplementation of the design and construction of assembled road structures using asphalt backfiringprocess to carry out research work. To deepen the design of assembled road structure, innovative processmethods, improve the construction quality and structural durability, reduce construction costs, scheduleoptimization, energy saving and environmental protection, as well as to promote the transformation andupgrading of the industry as the goal, the establishment of the new technology system of assembled roadstructure using asphalt backfiring process, the use of “H⁃shaped steel beam support design, longitudinaland transverse cross prestressing, asphalt surface layer integration Laminated plate backfiring process, T⁃type plastic sealing strip inlay processing, inlay and force combination, asphalt surface layer secondarypaving” technical program, the overall follow the “ center section to both ends of parallel operations,standardized design, modular construction, mechanized operation ” as the principle, the technicalprogram by the experts to prove that the technical program has been proven by experts, which is feasibleand effective.
