Understanding and Using Asphalt

Asphalt cement, also called paving asphalt, is a compo-nent of hot mix asphalt which is primarily used to construct flexible pavements (blacktop). This material is different from the other two types of asphalt because it is semi-solid and highly viscous (resistant to flow) at normal air temperatures. Asphalt cement is liquefied by heating then ...
