    formula for converting cubic yards of asphalut to tons

  • #2
    Re: formula for cubic yards asphalt to tons

    I found data on crushed asphalt of 45 pounds/cubic foot, and asphalt concrete at 140 pounds/cubic foot.

    The densities differ greatly, so would be best if you knew more closely what type of asphalt it was. Or if you have the density of your specific kind that would be best. I could create the conversion formula for you if I knew the density.

      General Rule For Asphalt Is=length X Width=square Feet Divided By 9=square Yards X The Depth In Inches X .056 = Tons.

        I need to know the formula for converting yards to tons for asphalt. My son
        is doing some asphalt work and they have changed the measurements on him.
        Please help. I need it asap. Please send to email: ruby.mills@earthlink.net.
        Thank you for your help.
        Sincerely,

          length x width x inches thick for asphalt mat divided by 160 equals tonnage formula Note example 100w x 75L = 7500 x 3 inches deep = 22500 divided by 160 = 140.6 tons asphalt for proposed job calculation you must however take into consideration the smoothness of the base material density of the asphalt itself ex topping, binder, intermediate mix etc temperature upon breakdown compaction and weight of the roller also the % of grade of the overall area ex pushing of mix on steep incline This is a learned response due to experience achieved through years of paving acceptable tonnage over a job requiring 100 or more tons lets say would be 90 tons laid by contractor 50 tons required 45 laid any thing less within 1-2 tons of goal this is usually the norm based upon conditions above You cant get it perfect every time but close ask for a 2 year warranty

            someone forgot the friendly period key. lets see if I can't help :]
            length x width x inches thick for asphalt mat divided by 160 equals tonnage formula. Note example: 100w x 75L = 7500 x 3 inches deep = 22500 divided by 160 = 140.6 tons asphalt for proposed job calculation. you must however take into consideration the smoothness of the base, material density of the asphalt itself; ex topping, binder, intermediate mix, etc. temperature upon breakdown, compaction, and weight of the roller. also the % of grade of the overall area; ex pushing of mix on steep incline. This is a learned response due to experience achieved through years of paving acceptable tonnage over a job requiring 100 or more tons. lets say would be 90 tons laid by contractor, 50 tons required, 45 laid. any thing less within 1-2 tons of goal this is usually the norm based upon conditions above. You cant get it perfect every time but close ask for a 2 year warranty.

            don't know what the last few sentences mean, but whatever

              Great formula, I'll be using that from now on if it works tomorrow...

                A good, basic rule of thumb to use is 2 cubic yards of asphalt equals one ton of asphalt. Its not perfect... its actually about 2.025 cubic yards to the ton, but in a pinch it makes for an easy conversion.

                  I believe your units are reversed and it is more like 2 tons per cubic yard. At half a ton per yard, it would be lighter than water (and many woods), making it a good boat building material. If you throw a lump of asphalt pavement in water, it clearly sinks.

                    Okay, how about this one. depth in inches/0.009 (0.00888889) x sq yd = total #s / 2000 = Tons ... i.e.
                    1"/0.009=111.11 x 18 sq yd = 2000# / 2000 = 1 ton.

                    or in my case

                    1"/0.009=111.11 X 7880 sq yd =875555.56#/2000=437.78 (443.24995)

                    When compared to

                    JohnS 2.025 per CY = 443.25

                    and

                    Superior Paving LxWxD"/160 which yealds 443.25 as well.

                      I have 1,623 tons of asphalt. How many square yards will it make.

                        Depends on how deep you want to lay your asphalt down.

                          In this formuila where are you getting the 160 as a dividing number and why? The rest is understood

                            It appears to be a result of combining a density of 150 lb/ft³ with other conversion constants.

                            If length and width are in feet and thickness in inches, that product is ft²·in

                            then multiplying by 1 ft/12 in x 150 lb/ft³ x 1 ton/2000 lb results in tons
                            Combining the three numerical factors is equivalent to dividing by 160 (or multiplying by 0.00625)

                            150 lb/ft³ is 2.025 ton/yd³ as 1 yd³ = 27 ft³ and 1 ton = 2000 lb. As another poster noted, these are all variants of the same basic density. If length, width and thickness are always feet, feet and inches, the product can be converted to cubic yards by dividing by 324 (9 x 36), then multiplied by density (2.025 ton/yd³). It is easier to see how to modify the formula if the density is different. But all give the same result for the same density.

                              No one takes into consideration the density? really? The densities vary greatly depending on application and mix design. Here is a very simple formula INCLUDING DENSITY**

                              Crushed asphalt has a density of 45 pounds per cubic foot(for an example as well).

                              Length(35 foot) x Width(11 foot) x Depth(4inches/12 foot) = volume(128.33 cubic foot)

                              Volume(128.33 cubic foot) x Density(45 pounds/cubic foot) = Weight(5774.85 pounds)

                              Weight(5774.85 pounds) / 2000pounds/ton = Tons(2.887425 U.S. tons)

                              Just about 3 tons
