Blacktop 4 inches thick? unlikely. What's under it? Hope it's not concrete.
Basically you need to cut a 4 inch wide trench six feet long? Saw cut it and pry it up, this is only an hour job. You can rent a saw. I've heard you can do this with your circular saw but not tried it myself.
The original blacktop. Repaved once, patched once. I had a pro
out here last week -- he came out the morning after I called, even
though he knew the job was smaller than his company would want to do --
and he said it needs to be cut out, but his minimum was 3000 dollars.
Gave me a list of others with lower minimums, maybe $2000. I asked
him about doing it with a hammer and chisel and he said blacktop was
almost as hard as cement. Of course a pro in most fields thinks its
best if a pro does the work.
Yeah. It's open to a drain on one side, but the original drain opening
is obstructed by the extra blacktop about 4 inches high. The pro said
he'd never seen anything like it.
Does the saw have a particular name? I think I read about one that one
can operate while standing up!!
The same webpage mentioned this, and a diamond studded blade, but with a
7 1/4 inch saw, at most i could cut out 2 or 3 inches, and then how
would I get the rest. Less than 2 or 3 if I cut at an angle, which
somehow seems like the right thing to do. .

Lowes has a 14 inch concrete saw for rent. They say daily rates are $25 to
$65 depending on the tool, they also have hourly rates. I would be very s
urprised if you couldn't cut two 6 foot slots in half an hour or so. Maybe
also make a series of angled cuts every few inches so you can take it out
in pieces. Then pry it up with a crowbar or the end of a pick. You really
need to sawcut before any other method or you'll get a frayed sloppy trenc
h. A chisel would take you a week I think.
Anyway, I'd go to any tool rental place and tell them what you plan to do.
Spend $50 instead of $3000, make the cut and take the saw back, remove the
pieces at your leisure.
My neighbor dug a trench for a water or waste line with a weird backhoe. I
don't know what it's called. You don't drive it, it's a little tiny thing
pulled behind a vehicle. It had a super small bucket, like 4 inches wide
maybe, and you stand behind it and move levers, or maybe it had a small sea
t, but no cab. It took him all day to dig a short trench but it looked goo
d. But that was in soil, it would never work on blacktop without the saw c
Wow. I went to Home Depot, where your link is from, today, Friday, and
the guy didn't know anything about this. He showed me a saw, a Hilti
700, that you use while kneeling or bending over, I guess, and I asked
him about something I could use standing up, but he had no idea, at
least at his store he said when I asked what he meant.
They should have a catalog and make them read it so the "associates" can
send people to other stores.
I have a reply to Tim, too, but it's probably longer and it's late.
This got buried in a different thread about digging out a crawl space, so
you may want to post it as a whole new topic.
Any chance that you could post a photo or two? Is the section of asphalt
that you want to cut out easily accessible and in an open area where any
type of saw or jack hammer could be used to get to it? From your
description, I am guessing that you just want to cut out a 4 inch wide strip
out of the existing 4 inch thick asphalt.
I would also be interested in knowing what the purpose of doing this is
(such as to put in a pipe etc. in the 4 inch trench), and if you will be
patching/replacing the asphalt after it is done.
If it is just about cutting out a 4 inch wide section of the asphalt, a
large circular saw does seem like it should work. The walk behind kind that
someone posted about may be fairly heavy and may need a pickup truck or
whatever to get it to and from the rental place. Depending on where you are
located, there may be a general tool rental place nearby, or even a
contractor tool rental place that also rents out heavy equipment etc., and
either one should have the walk-behind saw to rent if you wanted that.
If I were renting a circular saw to do the cut, I don't think that I would
worry about getting one that is a walk-behind type. It is such a short cut
(actually 2 cuts) that I would be fine if it meant kneeling on the ground
next to the saw while cutting. I don't think it would be heavy work, and if
it were me, I would just take my time and do it slowly on a cool day --
maybe in the morning.
Another option may be to just hire a handyman-type contractor to do the cut
with me paying for the saw rental if needed.
Or, I see concrete people cutting out old concrete (sometimes mis-poured
concrete) all the time. I assume that any one of those companies could do
that for you although they may charge more than a handyman-type person would
Or, maybe just post an ad on Craigslist describing the job as a "small job",
"cut out 4 inch wide strip of asphalt", etc. and maybe throw in a photo or
two. I could picture someone there saying they could do it for 100 bucks,
maybe even using their own saw.
It doesn't sound like a job for an electric jack hammer to me although that
may work. But lugging the jack hammer to and from the work site and lifting
and repositioning the jack hammer a bunch of times could be tedious.
That's probably why on their website, after you tell them where you are,
they list the aisle and bin of whatever you're looking for. It's not
foolproof but it's saved me from long hikes looking for
a. the thing
b. an associate
I like to walk, but I'd rather be out in the woods while I'm doing it.
If it's just to run wiring or a pipe under a sidewalk, the OP might be able
to hydraulic his way under the pavement:
There are commercial machines, but with a little PVC and fittings you can
easily make it through in most soils.
The link that you posted is interesting.
One problem may be that the link was about tunneling under concrete, but the
OP is dealing with an asphalt driveway. I think that most likely there is
compacted stone under the asphalt driveway rather than just dirt or soil, so
the water tunneling idea may not work.

The conveyor belt is one option for removal if you are a solo act. If you
have more help, I would use sleds. Check out http://www.indianacrawlspace
