As an asphalt binder modifier, the unique properties of Gilsonite ® uintaite make a road that is less susceptible to hightemperature and deformation performance issues. When these modified binders are used in recycled asphalt pavements,Gilsonite ® adds back what time has taken from the old asphalt, making it easier to use more of this recycled material.

Asphalt roads are made of a mixture of aggregates, binders and fillers. The aggregates are typically iron and/or steel slag, sand, gravel or crushed rock, and they are bound together with asphalt itself, which is a bitumen. Asphalt comes from natural deposits, or more commonly, as a byproduct of the petroleum industry. It is a prevalent material for waterproofing, caulking and preserving, and

Paving Materials ASPHALT DEFINED The black cementing agent known as asphalt has been used for road construction for centuries. Although there are natural deposits of asphalt, or rock asphalt, most used today is produced by the oil refining industry. Asphalt is a constituent of most petroleums and is isolated through the refining process of distillation. (See Figure 21.) Asphalt is called a

Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt 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. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century.

Today, asphalt is one of the most recycled materials. Reclaimed asphalt pavement, derived from reconstruction or resurfacing of existing roads, is reused in new asphalt mixtures. Cold recycling technologies and lowtemperature asphalt technology are being implemented, thus, conforming to sustainable development policies. Lower asphalt mixing and paving temperatures minimize emissions

Considering asphalt is one of the most recyclable materials in the world—particularly in the paving industry—there''s pretty much nothing it can''t do. When it comes to repaving or repairing roadways and commercial parking lots, most commercial contractors often source the very asphalt they''ve removed from the property to perform these jobs. Hence, compressed rock asphalt is born. The

An average asphalt pavement consists of the road structure above the formation level which includes unbound and bituminousbound materials. This gives the pavement the ability to distribute the loads of the traffic before it arrives at the formation level. Normally, pavements are made of different layers:

Asphalt road surfacing materials include composite materials used to create a smooth surface for roads and airport runways. All asphalt road materials use asphalt—a naturallyoccurring viscous liquid or semisolid form of petroleum also known as bitumen—as a binder. For example, asphalt concrete consists of mineral aggregate mixed with asphalt, which is then deposited onto the ground and

The asphalt on roads is driving air pollution. By Sustainability Times on September 7, 2020. Pollution Transportation. If we wanted to pinpoint the main source of air pollution on roads, we would point at the vehicles. But there is another source of air pollution on roads, scientists say, and that source is the asphalt used in the roads themselves. "Asphaltbased materials are abundant and a
