Asphalt usually means one of two things: 1) asphalt cement or 2) asphalt pavement. Asphalt cement, also called bitumen, is a viscous black liquid refined from crude petroleum or mined from natural deposits. When asphalt cement is heated and mixed with aggregate, it can be used to create asphalt pavements, also sometimes called tarmac or blacktop. The exact composition of a pavement depends upon the project specifications and intended use, but they generally contain a mix of fine and course aggregates (rocks and sand) of differing sizes. About 5% of a typical asphalt pavement is made of asphalt cement, which acts as a binder to hold the aggregate together.

∙ 13y agoThe experts on asphalt Dodge this question, because the exact, complex nature of the chemicals varies so widely, but they are all low-grade products of petroleum science. Asphalt (also called "bitumen") is an extremely thick and viscous substance used to bind aggregate (fine gravel) into road surfaces.
