Type of conduit for cable under ground

[Ainsley Whyte]

Team can anyone shed some light on the require conduit to be used when burying cable under ground.
I am running a 4/0, 4 core SWA cable under ground (where 10 Meters is road way) where trucks and other heavy equipment frequently traverse.
Can you suggest type of conduit ? or approved method ?

I would use concrete encased PVC, and maybe add reinforcing rods for the concrete under the roadway.

What don_resqcapt19 said. I would check if your firm or client has any Specs/Standards available for ductbank requirements when routed under the roadway. Are there any existing underground utilities that you need to locate?
