How is riprap weight calculated?
How is riprap weight calculated?
Multiply the riprap’s cubic yardage by its density. For example, if the you are calculating the weight of 15 cubic yards of gravel: 15 × 2,700 = 40,500 lb. Divide this answer by 2,000, which is the number of pounds in a ton: 40,500 ÷ 2,000 = 20.25. This is the riprap’s weight, measured in tons.
