asphalt concrete mix
Asphalt Concrete Mixture - an overview | ScienceDirect
Asphalt mix concrete must be thoroughly heated during mixing, transport, placement, and compaction. The asphalt binder used in asphalt mix may be stiff and brittle at room temperature, so that once this type of asphalt concrete cools it becomes stiff and strong enough to support heavy traffic. Cold mix asphalt, on the other hand, is normally ...
