Robby I'm an asphalt paver this old timer awhile back gave me this formula to figure out how many tons of asphalt it would take for a square foot measurment it works perfect I'm usually within a half of a ton extra when I'm done paving a driveway/parking lot ect. the formula is this.

square feet-divided by 9-times 112-times thickness-divided by 2000 pounds

what is the divided by 9 and the times 112 mean what are those numbers he told me what they were but I cant remeber I've figured out so many jobs with this formula I do it almost unconciously you know. If you can help me out with this that would be great its driving me nutts under this is an example maybe there is something out there thats even better to figure out asphalt.

2389 square feet-div by 9-times 112-times 3inch thick-div 2000=44.5946667tons I would usually round up to the next number always good for alittle extra so call it 45tons
