Thanks for the correction.  I took the first value I saw.  I also now see a value of 7.91 pounds per gallon, which nets 11,125 gallons.

 

The 10000 gallon value makes sense when viewing the tank car in the photo.

 

Thanks,

Steve Hile

Using Google conversions, 88000 pounds of asphalt would be about 607 cubic feet which converts to about 4540 gallons.  So, a fairly small tank car.

Whoa there! It looks like Google is using a density for asphalt pavement, which would be around 145 lb/cf. What you want is the density of liquid asphalt, which isn't much greater than that of water.  A specific gravity of 1.04 would be about 65 lb/cf or 8.7 lb/gal.  88,000 lbs is a good match to a fully loaded 10,000 gal tank.
