Abstract:The study’s overall objective is to examine different concrete removal methods to decrease traffic closure time due to the preparation process for partial depth replacement. This effort is intended to improve the efficiency of concrete removal methods as well as evaluate the life cycle sustainability of the techniques. To achieve this objective, the following specific research objectives are identified: • Identify from the existing literature commonly used concrete patch removal methods used in partial depth bridge deck repair. • Quantify the removal time for commonly used concrete patch removal methods. Identify additional techniques that decrease the removal time of partial deck patches and that may be automated. • Determine the environmental sustainability of different concrete removal techniques relative to partial bridge deck removal. • Determine an optimized removal method that accounts for both the time efficiency and environmental impact.
