The use of cold mix asphalt concrete for permanent resurfacing reduces inconvenience to the driving public by eliminating the usual secondary step of removing temporary resurfacing and applying hot mix asphalt concrete. It also considerably reduces construction spoil that must be landfilled or recycled.

Asphalt concrete is used in the construction of roadways. Cold mix asphalt is primarily used as a patch for road surfaces. Mixed with soap and water, the asphaltic bitumen is emulsified and mixed with the aggregate. As the water evaporates from the mixture, the asphalt hardens and takes on the characteristics of hot mix asphalt concrete.
