Open-graded friction courses (OGFC) are a porous asphalt surface course used on highways to improve driving safety by removing water from the surface. These use an open-graded mix design for the top layer of asphalt. Unlike a full-depth porous asphalt pavement, OGFCs do not drain water to the base of a pavement.
A more durable road surface (modern mixed asphalt pavement), sometimes referred to in the U.S. as blacktop, was introduced in the 1920s. Instead of laying the stone and sand aggregates on the road and then spraying the top surface with binding material, in the asphalt paving method the aggregates are thoroughly mixed with the binding material ...
The surface texture characteristics of SMA are similar to Open graded asphalt (OGA) so that the noise generated by traffic is lower than that on DGA but equal to or slightly higher than OGA. SMA can be produced and compacted with the same plant and equipment available for normal hot mix, using the above procedure modifications.
Mastic asphalt is a type of asphalt that differs from dense graded asphalt (asphalt concrete) in that it has a higher bitumen content, usually around 7–10% of the whole aggregate mix, as opposed to rolled asphalt concrete, which has only around 5% asphalt. This thermoplastic substance is widely used in the building industry for waterproofing ...
Asphaltite (also known as uintahite, asphaltum, gilsonite or oil sands [1]) is a naturally occurring soluble solid hydrocarbon, a form of asphalt [2] (or bitumen) with a relatively high melting temperature. Its large-scale production occurs in the Uintah Basin of Utah and Colorado, United States.

Asphalt batch mix plant A machine laying asphalt concrete, fed from a dump truck. Asphalt concrete (commonly called asphalt, [1] blacktop, or pavement in North America, and tarmac or bitumen macadam in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams.
