Spike s Compaction Factor Calculator

Assume you are using dry gravel with a swell percentage of 15 and a shrink percentage of -7 . Plug those values into the calculator and it will tell you that the compaction factor = 1.237. Multiply the 1185 cubic yards by 1.237. 1185 1.237 = 1465.9. To complete this job you will need 1465.9 cubic yards of this gravel in loose state volume.
