  • 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 ...
