    Determining Moisture in Aggregate for Mix Proportioning .

    The total moisture measured in the test represents both the free moisture and the moisture that the aggregate absorbs. Only the free moisture becomes part of the mix water. The absorbed water, usually about 1 percent, remains within the aggregate. If the coarse aggregate is unusually porous, the absorption should be determined by a separate test.

    Moisture Content - Pavement Interactive

    Since aggregates are porous (to some extent) they can absorb moisture. Generally this is not a concern for HMA because the aggregate is dried before HMA production. However, this is a concern for PCC because aggregate is generally not dried and therefore the aggregate moisture content will affect the water content (and thus the water-cement ratio also) of the produced PCC and the water content .
