I have a sub contractor who placed asphalt pavement for me and he invoiced by the ton. The Architect pays by the Cubic Yard. We placed 423.36 tons of type I asphalt 1 1/2" thick. We placed 641.64 tons of Type II asphalt 2 1/2" thick. Please, Please tell me how to make this conversion. I really need to understand so I can address this in the future too. Thanks

Re: Convert Tons to Cubic Yards
I tried searching for the density of #57 stone but came up empty. You may have to weigh a known amount and use that for the density.
Though it doesn't have to be as much as a cubic foot. If its a gravel type rock then just fill up any known volume, such as a gallon milk jug. You'd get the weight/gallon density which can be converted to pounds/cubic yard.

Re: Convert Tons to Cubic Yards
Nice info unregistered but where did you find the reference? I will use the 1.35 tons figure in my stone calculations but I am searching for a general reference that gives figures for other stone sizes as well. Let me know if you find it thanks, Sonny.

If you have crushed stone it's not quite as simple as that. Depending upon the stone size there is a considerable void volume. In smaller crushed stone, say 1 inch size, the volume of the voids is lower (about 25%) than in larger stone where a cubic yard of 6" stone may have a volume of voids of 35%.
Therefore, with a solid stone of granite that has a weight of 165 lbs per cu ft., the voids are equal to about 40 lbs (25% of 165 lbs. fo 1 inch crushed) or the 1 cu ft of 1 inch crushed stone ia about 125 lbs per cubic foot or 27 times that for a cubic yard = 3375 lbs per cu yd. If one then divides by 2000 lbs per ton you get about 1.7 tones per cu yd. of 1 inch crushed granite.

Re: Convert Tons to Cubic Yards
Your best bet is to call a quarry in your local area and ask to speak with a sales representative or someone in quality control.
As far as tons per cubic yards on the #57 Stone; 1.185 tons equals one cubic yard.
Here are some others that may help you...
#4 = 1.110
#5 = 1.092
#57 = 1.185
#67 = 1.164
#89 = 1.188
#9 = 1.273
This is all based on Miami Oolite limestone.
