Re: Conversion chart tons to cubic yards
I would guess closer to 1.2  1.4 ton/yd³.

Excavation of 6 "concrete in an area the 8,985 SF. were used 831.81 SY the asphalt in the same area. Why 202 CY Foundation Material Item 4 with the compaction of 10 tons roll were placed

Re: Conversion chart tons to cubic yards
I need to convert 300 cy of 1/4 ton riprap to tons. Any suggestions?

Typically, riprap is large stone in the range of 1.35 to 1.5 tons/cy^{3} but is dependent on the size and base material used.

Re: Conversion chart tons to cubic yards
19 CY = 513 Cubic Feet
Asphalt Unit Weight is Approx 145 lbs per Cubic Feet 513 x 145= 74,385 lbs =37 Tons

Re: Conversion chart tons to cubic yards
Where am I going wrong?
We had 2A modified, R3 rock and foreign borrow delivered to our jobsite. The quanitites are delivered in tons and paid for in cubic yards and I must make the necessary payments. I am having a great deal of difficulty finding the correct information to make my conversion from tons to CY. I will use the 2A modified material as an example. I understand that I must used the specific gravity of the material to convert from tons to CY. Utililizing the reade.com webite, I used a value of 1.47. This would be an average value between the Limestone, broken quanity (1.55) and the Limestone, pulverized quanity (1.39). Now I multiply that by 62.4 and get 91.7 lb/cu. ft. Ok, so, I take my delivered amount in tons, which is 22.4 tons and multiply that by 2,000 to get pounds  44,800 pounds. This represents one triaxle load. Then I take 44,800 pounds and divide by 91.7 lb/cu.ft., then divide by 27 to get CY. My final answer is 18 CY, except that a triaxle only holds 12 CY. Where am I going wrong?

I would review whether the load was weighed accurately, or was delivered damp. Damp or wet material is considerably heavier and if you pay by weight, you are buying water.

Bear in mind the data on Readme.com (and others) makes no mention as to the moisture content of most of the listed materials. It’s simply an industry average. I suggest you call the S&G pit and double check what their tons/LCY conversion factor is and . . . I strongly suggest you weigh a known volume, then interpolate that data to tons/cubic yard. Wouldn’t be the first time a S&G pit has made a slight error on their conversions. I have run across that problem a few times, and amazingly, it’s always been in their favor! Go figure.
