Successful Approaches for the Use of Hydrodemolition for Partial Depth Removal of Bridge Decks

This report summarizes the findings from the scan “Successful Approaches for the Use of Hydrodemolition for Partial Depth Removal of Bridge Decks.” The purpose of the scan was to investigate and exchange information with users of hydrodemolition to document their specific applications. The team examined case studies of bridges undergoing hydrodemolition as well as bridges that have undergone past hydrodemolition deck replacements to examine both the process and long-term performance of bridges that have been subject to a partial deck replacement involving hydrodemolition. The team explored various aspects of the hydrodemolition process, gathering perspectives of agencies, contractors, and consultants experienced in hydrodemolition. A scan team consisting of representatives from state departments of transportation (DOTs), the Federal Highway Administration (FHWA), and the American Association of State Highway and Transportation Officials (AASHTO) was formed to guide the scan and develop findings, recommendations, and implementation actions. This scan team met with users of hydrodemolition and documented their specific applications. The team examined not only bridges recently undergoing hydrodemolition but also bridges that have undergone past hydrodemolition deck replacements to study both the hydrodemolition process and long-term performance of bridges that have been subject to a partial deck replacement. The team explored various aspects of the hydrodemolition process, gathering perspectives of agencies and contractors experienced in hydrodemolition. The team specifically focused on how DOTs determined applicable candidates for hydrodemolition, specified construction requirements, and evaluated performance.
