Asphalt Pavement SPRR to Settle the Seepage of Asphalt Concrete Decking in Bridge: Mechanism and Effect

This paper discussed the common technologies in treating seepage of bridge deck and put forward the inevitability of choosing asphalt pavement SPRR technology to treat seepage in bridge decking. Meanwhile, it probed deeply into its mechanism and proved the validity of SPRR technology through the application of actual cases. Treating the microcosmic structural fatigue failure of decking in recoverable rejuvenate restore technology can combine the rejuvenated material and original decking together so as to form a unified whole. In this way, it may seal the micro cracks in bridge decking and thereby improve its porosity in order to achieve its waterproof effect as well. This technology is an important technical way to realize the sustainable healthy development between bridge operation and maintenance
