Cover for a reinforced concrete pipe culvert
Cover for a reinforced concrete pipe culvert
(OP)
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.

Also, you may want to download the "Concrete Pipe Design Manual" at this link (see Chapter 4)

Finally, if it turns out that you do need more cover, perhaps an equivalent elliptical shaped pipe can be substituted for the 18" circular RCP.
