  • Convert Tons to Cubic Yards

    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

    You need to know the density.

    I found data on crushed asphalt, but I do not know what is meant by type I and type II asphalt.

      I have 11 tons of asphalt but our specs say we need so many cubic yards of asphalt how do I convert it to cubic yards?

        Re: Convert Tons to Cubic Yards

        You need to know the length and width (or the area), in addition to the thickness.

        length in yards * width in yards * thickness in yards = cubic yards

        area in square yards * thickness in yards = cubic yards

          I'm a new superintedant for a construction company. I have a similar question, but I'm trying to convert #57 stone from cubic yards to tons. This information would help me for many years I am sure. Any help will be appreciated.

            just weigh 1 cubic foot of your stone. 1ft x 1ft x 1ft.Then multiply that weight by 9....that is how much 1 cubic yard weighs

              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.

                ? MULTIPLY BY 27 (27 CUBIC FT IN A CUBIC YARD)

                  1 cubic yard = 1.35 tons (approx.)

                  Therefore, 1 ton = 0.7407 cubic yards.

                  Hope it helps.

                    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.

                          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.

                              It would be 1,089 yd^3
