Rock asphalt, with its variable and relatively low content of bitumen, tends to be found away from the places where bitumen is needed. It is costly to move around and to process. It is important to draw the distinction between bitumen and coal tar. Although coal

Having the asphalt suspended in water allows the placing temperature for a BST to be significantly lower than for a hot mix asphalt. A surfactant offers two benefits – one, it causes asphalt to form tiny droplets that will suspend in water by lowering the surface tension between the asphalt and the water.
Bitumen is used as a binder in road construction and in protective coatings and adhesives used in the construction industry. In the most common processes the bitumen is heated to 100-200 C until fluid enough to mix with aggregate. The ‘hot mixed’ materials

5/8/2010· Coal tar bearing emulsions were used in the Netherlands as binder in anti-skid surfaces for runways because of their perfect adhesion and fuel resistance properties. They are however toxic and will not be allowed anymore after 2010. Therefore alternatives need to be developed. As one of the alternatives, two types of two-component epoxy modified bitumen have been investigated by means …

The hot-mix asphalt concrete is the most used in road construction, and the compounding of bitumen with mineral material is carried out at relatively high temperatures (160–170 C). It should be emphasized that a disadvantage of modern adhesive modifiers for bitumen is that they demonstrate a low thermal resistance (up to 120–175°C), while for some systems there is a rapid loss of adhesion

‘Tar pits form when crude oil seeps to the surface through fissures in the Earth''s crust; the light fraction of the oil evaporates, leaving behind the heavy tar, or asphalt, in sticky pools.’ ‘Still impure, the gas was then passed through condensers and scrubbers to remove tar, and then through iron oxide purifiers to remove other impurities.’
