AASHTO R 73-16 (2020) is a standard practice that outlines the evaluation process for precast concrete drainage products. It specifically focuses on products such as pipes, box culverts, manholes, and drainage inlets. The standard provides criteria for determining the acceptability of these products, as well as guidelines for repairing products that do not meet the required standards. The standard applies to both wet cast and dry cast production methods, and covers the inspection of finished products manufactured according to specified ASTM standards. The evaluation guidelines provided in the standard focus on conditions such as cracks, manufacturing defects, and damaged ends. It should be noted that this standard practice is not intended for evaluating precast concrete products that have already been installed.
