Standard Weights for Crushed Rock Per Meter | Hunker

General Weights. Solid rock is estimated at 2.5 to 3tons per cubic meter. If rock is crushed into uniform sizes, the presence of open space between the particles causes the load to be lighter -- approximately 1.6 tons per cubic meter. Mixed sizes of crushed rock can range from 1.6 to 2.2 tons per cubic meter.

Crushed Stone: Determing Yards Per Ton

Crushed stone is quoted at a weight of 2700 pounds per cubic yard. Your stone dealer tells you he has a truck that can deliver 20 tons of stone per load. You need to know who many cubic yards that comes out to. Here is the math: 20 tons X 2000 pounds per ton = 40,000 pounds. 40,000 pounds / 2700 pounds per cubic yard = 14.29 cubic yards.
