asphaltbitumen

Asphaltbitumen, often simply referred to as bitumen or asphalt, is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. It is primarily composed of a mixture of organic compounds called asphaltenes and maltenes. Bitumen is a component of crude oil. Refining crude oil separates it into lighter fractions such as gasoline and diesel, leaving behind bitumen as a residue.

The most common application of asphaltbitumen is in road construction, where it acts as a binder in asphalt concrete, the primary material used for paving roads, highways, and airport runways. When mixed with aggregates like gravel and sand and heated, bitumen creates a durable and flexible pavement. Its adhesive properties allow it to bind these aggregate materials together, forming a strong and cohesive surface that can withstand traffic loads and environmental conditions.

Beyond road construction, bitumen has several other industrial uses. It is employed in roofing materials, such as asphalt shingles and membranes, providing waterproofing and protection. It is also used for insulation, sound dampening, and as a sealant in various construction and industrial applications. The precise properties of bitumen can vary depending on its source and the refining process, influencing its suitability for different uses.
