Blessed be the ties that bind. Therein is the key difference between concrete and asphalt: The binder.
Concrete and asphalt are both made with a mixture of aggregate. Concrete is bonded with a mixture of water and portland cement that creates a chemical reaction and hardens. Asphalt is bound with a black, sticky petroleum-based substance. This substance is behind terms like “blacktop” or “tarmac.”
Because of the key differences between the two products, concrete and asphalt contractors will offer different services to match the installation requirements.
