    Rationale

    For a given box culvert section, a wall thickness that is greater than specified is not cause for rejection per the standard. But, the standard does not address the location of the reinforcement resulting from a thicker wall. The purpose of this modification is to clarify that the location of reinforcement is to be based on the theoretical wall thicknesses for location within the section. Reinforcement this is properly located within a given wall section based on theoretical thickness is to be considered adequate if that section is thicker, in turn creating additional clear cover over the reinforcement.
