What type of asphalt is used on highways?

Asphalt Pavement Guidance

Common types of flexible pavement include hot mix asphalt (HMA), rubberized hot mix asphalt-gap graded (RHMA-G), and open-graded friction course (OGFC). There are also two types of rubberized OGFC mixes: rubberized hot mix asphalt-open graded (RHMA-O) and RHMA-O-high-binder (RHMA-O-HB).
