concrete roadway, just packed earth and rock? Environmental limitations do
My best guess is that you would want to use directional boring in that case. A small hole every couple hundred meters, horizontal bore and duct pullback
You'll struggle to get a directional drill through material that includes rock. It's two days work for this kit http://www.youtube.com/watch?v=acTBl8UKNaQ John
