Which components make up asphalt?

Asphalt is primarily composed of three main components: aggregate, asphalt binder, and additives.

Aggregate consists of materials such as crushed stone, gravel, and sand, which provide the structural strength and durability needed in asphalt. The asphalt binder, typically a petroleum product, acts as a glue, binding the aggregates together and giving the pavement its flexibility and resistance to deformation. Additives may be included in the mix to enhance specific properties, such as improving the asphalt's performance in various environmental conditions or extending its lifespan.

This combination ensures that asphalt can withstand traffic loads, weather conditions, and aging processes effectively. Consequently, the understanding of these components is crucial for anyone involved in asphalt paving and maintenance.
