    Determining Moisture in Aggregate for Mix

    The difference in weight represents the total moisture content of the aggregate. For making batch calculations it is handiest if moisture has been calculated as percent of the SSD weight of the aggregate. The total moisture measured in the test represents both the free moisture and the moisture that the aggregate absorbs. Only the free moisture
