Asphalt consists of a mixture of aggregates (approx. 95%) and bitumen (approx. 5%) heated to a temperature of approximately 120 degrees C, and delivered to the construction site in insulated vehicles.
Asphalt is laid and compacted while hot to form a smooth surface suitable for vehicles or pedestrians. The characteristics of asphalt can be varied by careful selection of the aggregates, the aggregates gradation, special binders and additives.
Development of sales volumes
Asphalt deliveries decreased by 5.8 % in the reporting year to 10.4 million tonnes (previous year: 11.0). Excluding consolidation effects, they remained at the previous year’s level. Sales volumes in Western and Southern Europe were significantly higher than in the previous year. However, they declined in the other Group areas. Africa-Eastern Mediterranean Basin recorded the heaviest losses.
