A. Units: The work described in this section will be measured and paid for by the cubic yard compacted in place for imported aggregate base material. Determination of quantities shall be as follows:

1. Loose Material hauled shall be weighed at a certified scale and tickets given to the Government.

2. Loose material hauled shall then be divided by the Loose Wet Density of the material to obtain the loose cubic yards delivered.

3. The loose cubic yards shall be divided by the Factor of 1.33 to obtain the compacted yards in place.

Factor Derivation:

25 percent shall be used for shrink and loss. 20% for shrink and 5% for loss.

Factor = 100% = 1.33 100%-25%

A. Payment: The accepted quantities will be paid for at the contract price per unit of measurement, respectively, for the pay item shown in the Bid Schedule. Price and payment shall be full compensation for furnishing and placing all materials, including all labor, equipment, tools, and incidentals necessary to complete the work described in this section.
