Bitumen which has increased hardness due to air being blown through it. Cut backs. Bitumen diluted with oil to make it more fluid at working temperatures allowing it to be painted on to surfaces. Bitumen emulsion.
(oil sands) are a combination of clay, sand, water, and bitumen, a heavy black viscous oil. Tar sands can be mined and processed to extract the oil-rich bitumen, which is then refined into oil.
Types of bitumen/Asphalt Asphalt cement. It is a semi solid hydrocarbon which is obtained when fuel oils and lubricating oil have been removed from petroleum. All the asphalt cannot be used as a binding material but Asphalt cement is preferably used for the road construction. There are two types of grades for Asphalt cement.
The word is derived from the Ancient Greek ἄσφαλτος ásphaltos. Bitumen is the glue that transforms aggregates into asphalt. It needs to be delivered in accurate doses, which is not possible with traditional mechanical flowmeters.
Formation of Bitumen. Bitumen usually forms in environments with abundant algae, plants, and other organic matter. Because of this, it typically forms under the same conditions as oil and coal, namely in lakes, marshes, and areas of high vegetation where plant matter can be preserved in mud deposits which become altered due to heat and pressure as they get buried.
According to the U.S. Geological Survey, bitumen is further distinguished as extra-heavy oil with a higher viscosity (i.e Start studying Bitumen. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Terms for bitumen Flashcards | Quizlet.
