Bore
Bore
(OP)
I need to run a 4" pvc line under an existing roadway. Is it necessary to jack and bore or is there some type of freebore that we could use? Thanks.

RE: Bore
Check with the authority.
If no casing is required, you can directional bore the line. This is probably your best bet; but, I've also seen contractors ream out a hole with a small service line type of boring machine and then push PVC pipe through by hand. I know this works on short punches (<30 ft) with smaller pipes (<8").
RE: Bore
We use almost exclusively directional drilling for our bores under roadways, which includes state highways where steel casing is required. Yes, you can use dd for steel, although it takes a lot longer tail ditch. We have used HDPE, Certa-lok PVC, fusible PVC, and schedule 40 glue joint PVC. Diameters that have been done are 14" to 24" steel and 2" to 12" HDPE and PVC.
RE: Bore
If you can use directional drilling as mentioned above, there will be a lot less material.
