**Soil Compaction Requirement Evaluation** A soil sample is obtained from a job site. Its maximum dry density, when tested in a lab, is determined to be 106 pounds per cubic foot (pcf). If the construction contract mandates a relative compaction of 98%, which of the following compaction measurements satisfies this requirement? (answers in pcf) - 100 - 102 - 104 - 106 **Solution Explanation:** To determine which compaction measurement meets the requirement, you need to calculate 98% of the maximum dry density: Maximum Dry Density (MDD) = 106 pcf Required Compaction = 98% of MDD Required Compaction = 0.98 * 106 = 103.88 pcf Therefore, the option that meets the requirement is 104 pcf, as it is the smallest value greater than or equal to 103.88 pcf.
