A local residential road is not up to specifications with 2 inches of
asphalt. BTW your driveway usually gets at least 2 1/2!
Expect a road to get 4 inches or so in 2, 2inch coats as a minimum

Original message below:
We haven't run on anything like that, however since the" running course" or
"top
course" is not present, the pavement will be rougher since there will be
less
fines in the asphalt mix. This will result in less traction and perhaps
some
"rough" areas (more voids) which may be more prone to breaking up IMHO.
Think
about driving over road construction sections of pavement that have not been
completed - you might want to physically take a look at it first to see if
it is
smooth enough to run on.....tar....etc.
Basically what the asphalt does is provide a water-proof barrier for the
gravel
base below, help to distribute the wheel loads to the road structure below
and
provide a smooth running surface with appropriate traction qualities. Local
residential streets may have as little as 2" of asphalt whereas collector
roads
and other major arteries will have 6" or more thickness to deal with the
wheel
loads of heavy trucks etc.
So there you have the "rest of the story". ;^)
