Earthwork Design | FHWA - Transportation

The total volume of earthwork is the sum of the volumes of the prismoids formed by adjacent cross sections. When using the average end-area method, the prismoid is treated as a prism whose cross section is the mean of the two end areas of the prismoid. Equation 9.5.1A (1) presents the formula for use in the average end-area method.

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.
