80ton of Road Base= how cubic meter
I do not deal in metric tonnes, but maybe the following will help. We use 25 short tons (2000 lbs per ton) is equal to 19 cubic yards.
It's usually between 130-135 lbs per cubic foot, depending on quarry, etc. etc.Converted to cubic yards (x27) = 3510 - 3645 lbs. per cubic yard
You will need 20 cubic yards or 25.7 tons of gravel.
22.70
No where near 1 ton.
1.60 tons
Yard and ton are very different units; check the spelling.
About 25 cubic feet, or almost one cubic yard. Road salt weighs 80 pounds per cubic foot
703.7
1.60 tons
4 yard weighs 6 tons so if you do the math 2 yards = 3 tons and 1 yards = 1.50 tons and to answer your Question 1 yard of base weighs 1.50 tons or 3000 Lbs
