Permeability of hot mix asphalt concrete as affected

One of the primary objectives when constructing hot mix asphalt concrete (HMAC) is achieving the target density in order for the pavement to be impermeable. If the density is too low, water infiltration causes pavement damage from freeze-thaw and other effects caused by the presence of water. If the pavement density is too high,
