I was not able to find any reference to State Top Asphalt on the web. I was able to find specific gravities for
compacted asphalt ranging between 2.15 and 2.50 with a preliminary estimate value of 2.35. This means that asphalt is 2.35 times heavy than water.
We can look up and find that water weighs 62.43 lb/ft³. There are 27 cubic feet to a cubic yard, so a cubic yard of water will weigh 1,685.61 lbs. Asphalt is 2.35 times heavier, so a cubic yard of asphalt is 3,961.18 lbs.
Using 2,000 lbs as a ton, that means that we have 3,961.18 / 2000 = 1.98 tons of asphalt per cubic yard, so one ton of asphalt will be about half a cubic yard.
(1 ton / 1.98 yd³/ton = 0.5048 yd³, for the truely pedantic)
