Professor Huang’s research has centred on long-span bridge steel deck paving, intelligent transportation systems, and pavement design theory and engineering application, with particular emphasis on the development and application of multi-component epoxy asphalt materials. He developed the multi-component epoxy asphalt material used in China and has contributed to the development of steel deck paving technologies for long-span bridges and intelligent transportation systems. He organised and led the design and engineering implementation of steel deck paving for nearly 30 long-span bridges, including the Second Nanjing Yangtze River Bridge, the Shanghai Yangtze River Tunnel and Bridge, the Sutong Yangtze River Bridge, and the Hangzhou Bay Sea-Crossing Bridge. His research on pavement design theory has addressed design indices and parameters, fatigue analysis methods based on energy dissipation principles, simplified pavement calculation methods, and pavement optimisation design. He also served as chief editor of the national technical standard Technical Code for Prestressed Concrete Pavement Engineering. Professor Huang has authored 256 peer-reviewed publications, including 212 indexed by SCI, EI, and ISTP, as well as 13 monographs, including Advanced Cement Concrete Pavement Design Theory and Methods, Advanced Asphalt Pavement Design Theory and Methods, and Expressway Database Application Technology, which have received more than 500 citations. His work has received 21 national and ministerial/provincial science and technology awards, including four National Science and Technology Progress Awards and 11 Ministerial/Provincial Science and Technology Progress Special Prizes and First Prizes. He holds 16 authorised invention patents. Collectively, these contributions reflect a sustained research programme connecting civil engineering theory with the design, construction, and management of major transportation infrastructure in China.
