Hi all. I am specifying a 18" reinforced concrete pipe culvert under a road with HS 20 loading. The pipe is barely under the base and there is no sub-base. In other words, the pipe is right below the base, with minimum thickness above the top of pipe. Is there a requirement for a minimum "cover" or distance before we could put the base above the pipe? The thickness of wear course is 3", base is 8". Thank you in advance.
