Just going from my own research here so I'm also waiting for others to
pipe
in but, the mesh or wire holds the concrete together and keeps it from
cracking.


okay, i'll "pipe in".... rebar / wire mesh on a concrete
driveway is a waste of money !

the key is preparation of the ground below it.

presuming the contractor puts in rebar / wire mesh,
what's he using to hold them up during the pour ?

i think the guys in alt.building.construction, that
i'm crossposting to, would have more to say on the
topic of concrete driveways and rebar/wire mesh.

i've seen HUGE driveways done with NO rebar at all,
and the surface is perfect years later. And that's
driving all kinds of heavy pick up trucks and trailers
onto it.

You can use the wire mesh if you wish. The concrete is poured over it
while the
concrete finisher walks into the wet cement and hooks it up off the
bottom. I
prefer to pour with the heaviest psi concrete that I can get and have
glass
mixed in it. Thickness is important. Some folks just lay 2"X4" lumber on
the
ground and pour cement to that height (3 1/2"). You want at least 4". If
you
can find a concrete supplier who will mix to DOT standards you won't have
any
problems and you won't need to add anything to the concrete.

3" of compressed roadbase is common under a concrete driveway around these
parts. Most use 3/8 tied rebar vice mesh wire. 2X4 forms are not unusual
here. They do dig up for 6" deep X 8" wide beams on the perimeter, rebared
too. 10'-12' sections allowing for expansion is common. Tying to the
street is critical. How they setup the apron and its reinforcement can make
or break it when a car creeps off the edge of the driveway.

Last heavy vehicle on this driveway of mine, same method of construction,
was a Dixie type dumptruck hauling 12 yds of sandy loam to my site. No
apparent damage.
