What are the different types of road surface materials? Asphalt. Asphalt, also known blacktop, is an umbrella term that covers a range of mixes used within the construction industry. The correct term is asphalt concrete. All asphalt concrete mixes use bitumen as a binder to cement together the aggregate particle components of the mix.
Asphalt is a composite material with two primary ingredients: aggregates and bitumen. Aggregates – usually crushed stone, sand and gravel – are bound together with bitumen (a viscous and waterproof substance) at high …
