Invented in the 1800’s, Asphalt is essentially a combination of aggregate and bitumen, which is derived from crude oil. Additives can also be incorporated to improve performance and durability, these take the form of fibres, wax, polymers and pigments. Asphalt is the most commonly used surfacing system and is used in the construction of roads, car parks, driveways, pathways and play areas. Asphalt is generally black, but can also be red, green, blue or golden.
