Steve's right...you're confusing paving asphalt (contains a lot of
gravel aggregate) and roofing asphalt (contains minor amounts of
finer fillers). Next time you drive by a highway surfacing project
note the big dump body trucks lined up there filled with hot mix. No
liquids there.



Then there's "hardtop", which is common in my area on lightly-loaded
roads: You lay down the usual packed-aggregate roadbed, then spray
really runny tar on the surface. Then you spread pea-gravel on top of
that, and just let passing traffic roll it in the rest of the way.
Excess gravel gets pushed off to the shoulder over time. It's fairly
durable if you keep heavy trucks off of it.

This is a terrible way to surface roads. It really plays havoc on your
skates after a icestorm. DAMHIKT!
