How Many Holes are Drilled/Mile for Anchoring on Highways?

[ArgoMix]

Road reflectors, light posts, rebar, threaded rods and various screen tubing need to be anchored in concrete with epoxy. I'm trying to get an estimate of how many holes need to be drilled/mile of new road.

 

Thanks!

Reflectors that are on the road surface are just glued on; no hole drilling.

Light posts may have a large hole drilled or dug to receive the concrete and the spacing may vary. Drive by some and measure how far apart they are using your odometer.

Rebar is neither drilled for nor epoxied. It is wired together, surrounded by forms, and the concrete poured over it.

Threaded rods for signs/lights/signals are often cast in place similar to the rebar. I suppose later additions may be drilled into existing concrete and epoxied but I'm not sure.

I don't know what you mean by 'various screen tubing'. ??

 

What's this all about anyway? School project? Work related? Selling epoxy? Idle curiosity?

Rule of thumb is 1 foot deep for every 5 feet of light pole. Usually the concrete footing is 2 feet in diameter.

Why would they use expensive epoxy when they can use cheap concrete?

Secondary bonding is much better, and it can sometimes reduce the labour costs.

As Acme pointed out, this would be appropriate for later additions, where the installation was not done with the initial setting of the concrete.
