What is Blacktop?
Blacktop is the common American term for asphalt paving, especially for residential driveways, private roads, and small parking areas. It's called "blacktop" because of the dark black color of the bitumen binder that holds the aggregate stones together.
Our blacktop calculator uses the same formulas as professional asphalt calculators to give you accurate tonnage estimates for your paving project.
