U channel installation

[Cynosure]

Can any pass along a little knowledge on the technique to install a new u channel post into an existing asphalt parking lot? I've lucked out that all my installs up to now have been into soil.

Any help as always is appreciated!

Use a post pounder, same as you would for soil, it takes a little more work to get through the asphalt but it should only be about 4" thick. If you have a lot to do, consider a gas or hydraulic post pounder.

I go with a 3' post first so as to get a good position to use a heavy sledge. then bolt the longer section to the embedded one. I usually try to break through the asphalt fist with a star drill chisel to make sure there is no concrete underneath. Most of the time they put a rock dirt fill and steam roll it down and level before asphalt is put down so when you get past that is should go smoothly unless you run into a large rock.

3" core drill (Buy or rent) then back-fill with a Quikrete Anchoring cement that sets in 10 minuets,

we pound straight through the asphalt...did 4 of them last week sometimes they are a little slow to start and keep straight. I am guessing not much fun for whoever has to try to remove them

Same thing here. Some strong chisel and if ya have pneumatic, even better. Drive a 30" or 3' piece down first and then attach a break-away kit to hold the top portion in place.

We just bid on a sign which is asphalt and below the asphalt, is another asphalt parking lot on top of about 6" of 2A stone on top of a concrete parking lot, which below that, is anybody's guess from stones then dirt, fill who knows.

The customer decided to put the sign on the wall, instead.

Thank you all for the input! Sounds like I should test and see how soft this asphalt is, and worst case bore a hole. Thanks again!

what about utilities? I usually mark for them anywhere i penetrate ground, (its free, why not) but dont want the black top all marked up on a new parking lot, they have to get the electric to the lights some how. luckily i lost the last bid on a brand new shopping center, but it'll probably come up again

If it's concrete (common around here) I use a hammer drill to get a hole started and use a big metal rod stabber thing to make it bigger, then refill it with bagged concrete.

I pay someone $200 to bore holes with a skid steer. Then have them remove the dirt. Easy Peezy.

Hammer drill the asphalt then pound in.
