Anyone done any DIY asphalt blacktop installation? I don't mean cold
patching, but actual hot asphalt? I have a small section of driveway
(about 15 feet long) that I would like to widen by about 2 feet.
I'd really rather hire this out, and I have called a bunch of
contractors for quotes, but once they find out it's a small job, I
never hear back from them.
Can I install a good compacted gravel base, get a load of asphalt
(where?), rent a small road roller, and do this myself? The existing
asphalt is in pretty good shape, although the edge is crumbling a bit,
so I'd have to remove a few inches.
Asphalt hot mix (compacted) is about 110 lbs per square yard per inch of
For your 2 x 15 feet, that's 3-1/3 sq yards, or 366 lbs per inch of
You want, what, 4 inches of depth, I'd guess?
So that's about 3/4 ton of hot mix.
The question is, can you haul, dump, spread, screed, and roll that much
material before it cools too much? You gotta roll it hot. It should be
placed at 230 to 310 deg F, and rolled soon after (I forget the min
rolling temp). If you've ever tried spreading loose gravel by hand, it
is surprisingly backbreaking work, and you tend to wildly underestimate
the time or effort required.
Call the local asphalt plant(s). They'll tell you how long you would
have to work a batch that size, and if you can expect your crew to
manage it. They will tell if they will supply that small a load in the
back of your pickup truck or whatever. Ask about tack coat material.
They will also have contacts to anyone who might do tiny jobs like that.

Richard, thanks for lot of good info and suggestions. I think I'm
going to keep trying to find someone to do this. I rarely turn away
from a DIY challenge, but this one just smells like a bad idea from
Yeah, nothing you want to tackle on your own.
I am having the same problem. I have a 20 X 30 foot "parking area" I want to
add to my existing driveway. I could only get one company to come out so far
and he wanted to charge me more that what the entire driveway cost.
What about doing the additional witdth portion with another material like
DIY paving blocks? It gives you the look of having a walkway next to your
driveway. You can remove the blocks, use them for something else and do an
all-asphalt drive when it's time to replace the main portion someday.
I did this with two rows on each side of the driveway. I used 12" square
pieces that looked like flagstone, about 1.5" thick. This gave me 4' wider
driveway. It looks great, and I get a lot of compliments on it. It really
dresses up the driveway. It was about $2 per square foot, but I think was
