Types of Asphalt
There are several types of asphalt paving available to homeowners and contractors. What type is right for your project? Learn about five common asphalt paving types below.

Hot mix – A combination of approximately 95 percent stone, sand or gravel bound together by asphalt cement, hot mix is heated and poured at 300°F.
Warm mix – Because it is mixed and shipped at lower temperatures, warm mix does not cool as fast as hot mix. It includes emulsions that make it easier to pour and spread.
Cold mix – This formula doesn’t require heat and is the most affordable asphalt mix. It is used to repair potholes and pavement cracks.
Cut-back – A combination of asphalt cement and petroleum solvent, cut-back asphalt is used for its decreased viscosity, or thickness. It contains volatile chemicals and is restricted in many areas.
Mastic – A dense and durable formula, mastic asphalt is a waterproofing medium. It is a mixture of asphalt, stone filler and mineral powder that is heated and mixed at hot temperatures.
