Why such a deep undercut for a driveway?

Pit Run is structural fill. Usually a good amount of 8" minus cobble with lot's of sand. it is mostly what we dig up here but some area don't have it and we have to import.0031 mt laurel 2012-08-28 12.42.41 (273).jpg0031 mt laurel 2012-08-28 12.42.41 (274).jpg0031 mt laurel 2012-08-28 12.42.41 (275).jpg0031 mt laurel 2012-08-28 12.42.41 (276).jpg

2' of pit run (bank run or run of bank out here) keeps things from turning to soup when the frost goes out in the spring.

Because we do it right out here CM. Minimum 2' cut and all pit run for roads and drives. 20 years no complaints.

There is no reason to do that in my area unless the existing soil is poor - heavy/expansive clay or high organic content. Frost line? What's a frost line?:D

Is pit run what we call crusher run?

Since our geology is quite different from out West, the closest thing to pit run in our area would be chert or in the southern parts of our States the sand/river gravel mix that is dug directly from the ground.

I dunno. You tell me. :beatsme


:rolleyes:

We haven't seen 6" of frost in my lifetime, somebody needs to re-draw that map.:cool2 Might get an inch if it gets down in the 20's at night for a few days but nothing to speak of. We only get snow maybe 1-2 times a winter but it's gone by the afternoon.:cool:

That map of the depth of frost is quite accurate I think. It was done one year after the ice age. He he

I chose that one because here, we dig footers down to 36" to protect for frost. Waterlines get 40"-48" of cover. And I agree, I've never seen frost that deep. The point is though, that you can get frost well SOUTH of the Mason Dixon Line. A couple hundred miles NORTH of that, it can be lots deeper. :cool2

See if you like this frost map any better. I have seen it pushing 18" here, but it was a really cold winter.

And to get things back on topic, the second pic is of a Link Belt 135 zero tail swing excavator. It was a rental that we had on the job for a couple of months. Nice, because it was on rubber tracks, so it could walk all over the neighborhood without tearing up the streets. I didn't get much time on it, but I got enough to say I have a positive impression. (Only real complaint is that they only put steps on the side of the undercarriage at two of the corners. If you want to stop and climb down, you need to have the boom lined up with the tracks. Stop it with the boom swung to the side, and there's no step there. How much would it cost to put one at every corner??)

Digger, you might as well accept those maps probably came from the govt. and are thus useless. I live under one of the dots in the 6" line on the first one, and 50 miles south of the 5" line on the second.

I have never in my life seen 1" of frost, 1/4 is unusual.

On further thought I bet they made those maps so the global warming folks could claim that's the way it used to be? :beatsme

Basically had it ready to go, Had found a nice Ranco 36' end dump for it as well. The end dump got sold out from under me. Then we lost a recap in my t600 and it blew out two batteries in the battery box. So, we have started using her for parts. Hopefully, by winter I have her all set up. It's always something.
Regards, CD
