asphalt concrete mix characteristics

7 MUST HAVE PROPERTIES OF ASPHALT CONCRETE

This hot asphalt mix is the most common mix used because it can provide great impermeable characteristics allowing water to run away from the surface area The name comes from the aggregate size used while mixing the raw materials to produce the asphaltic composition.
