asfaltskikt

Asfaltskikt refers to a layer of asphalt, a composite material commonly used in road construction and roofing. It is typically made up of a binder, most often bitumen, and an aggregate of mineral materials such as gravel, sand, and crushed stone. The bitumen acts as the glue that holds the aggregate particles together. Asphalt is a thermoplastic material, meaning it softens when heated and hardens when cooled. This property is exploited during its application, where it is heated to a workable temperature, spread evenly, and then compacted to form a dense, durable layer.

The primary function of an asfaltskikt in road construction is to provide a smooth, wear-resistant surface for vehicles. It is part of a larger pavement structure that includes base and sub-base layers designed to distribute traffic loads to the underlying soil. Asfaltskikt can vary in composition and thickness depending on the intended use, traffic volume, and climate conditions. Different types of asphalt mixes exist, such as hot mix asphalt (HMA) and warm mix asphalt (WMA), each with specific manufacturing and application processes. Beyond roads, asphalt is also used in applications like sidewalks, driveways, and in some roofing systems.
