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.

Please help. I need it asap. Please send to email: ruby.mills@earthlink.net.
Thank you for your 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 12 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

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.

Re: formula for cubic yards asphalt to tons
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.

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

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.

Re: formula for cubic yards asphalt to tons
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
