In this communication, the pavement repair strategy for the Bangabadhu multipurpose bridge has been optimized. The former design of the repair strategy includes six parts of repairing cracks with epoxy adhesive, 1.4 mm thick carbon fiber reinforced polymer (carbon fiber reinforced polymer), 5 mm thick thermal insulation, 6–12 mm surface material non‐shrink mortar grout, 5 mm thick waterproofing membrane, and 50 mm thick mastic asphalt. The optimized repair proposal includes five parts of repairing cracks with epoxy adhesive, 1.4 mm thick carbon fiber reinforced polymer, 4–10 mm thick epoxy resin motar grout, 5 mm thick epoxy asphalt waterproofing adhesive coat, and 50 mm thick stone mastic asphalt. In addition, the requirements for the materials selection and specific technology for the construction processes has also been provided.

This paper had developed C100 high-performance concrete (HPC). Mechanical properties of high-performance concrete after evaluated temperatures were investigated. Besides, this paper had summarized the extrinsic characteristics of HPC after evaluated temperatures, which was effectively applied in evaluating the temperature experience of concrete structures. Shear strength between HPC and rolled steel plate after evaluated temperatures was experimentally studied with the facilities of specially designed loading device. Mathematical model of shear strength was proposed, which can be used in both engineering and numerical simulation.
