Abstract

<abstract abstract-type="main" xml:lang="en" id="mawe201400255-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p xml:lang="en">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.</p> </abstract>
