Mar 01, 1986 Newly delivered sand, in the early part of the day, will have more free moisture. After a rain the sand may briefly have even more than 6 percent moisture.The coarse aggregate contains less free moisture and varies less. You may have as little as 1 pound of free moisture per 100 pounds of gravel or stone, and seldom more than 2 pounds (1/4 gallon).

Moisture Content - Pennsylvania State University

The moisture content of aggregates in the field is much closer to the SSD state than the OD state. The bulk specific gravity (BSG) of aggregates is more accurately determined by the displacement method in the SSD condition. The moisture content can be calculated directly from measurements of (BSG) using the displacement method. Absorption Capacity:
