Help on Culvert to support heavy weight
(OP)
Hello All and sorry if this is a redundant question. I am the owner of a property in Northern Calif south of Red Bluff,CA. I want to put a culvert in to access the property from the asphalt county road. I was looking to put a steel 30" culvert which has 34" from the flow line to grade. In the near future I am looking to build a ICF concrete house and need some advice on what to do so this culvert will support the weight. Steel or black plastic ? The county permit says steel or black plastic no concrete. Any ideas or recommendation would be appreciated. )
Thanks once again and sorry about the redundant question

I left that out but I am looking to put two each 30 inch diameter culverts with 36" flare ends (skirts) in the ditch.

Another option is to place a reinforced concerete pavement slab over this area. A structural engineer can design this to spread out the pressures to tolerable levels.
Then another option with this, you can use the "imperfect ditch" method first recommended by an old Iowa prof., named "Spangler". Before placing the slab spanning the pipes, you add a compressible material as cover over the pipes, such as corn stalks, sawdust, leaves, etc. This mainly is used where the pipe is already in and you are adding more fill, bigger loads, etc. It works.

I like a corrugated black plastic with crushed (angular) 3/4" rock up to the springline (halfway) just make sure you flush and compact it.
This may still help,
Get the concrete trucks to go slow, one of the biggest impacts is a bumping truck. At my house, I have a turn that slows the traffic so running concrete and gravel loadded trucks with only 8" to 12" (different sides of the pipe) for a HDPE 24" pipe has shown no impact. Also make sure the approach and exit remain smooth and no source of pumps appear.
