bitumen, dense, highly viscous, petroleum-based hydrocarbon that is found in deposits such as oil sands and pitch lakes (natural bitumen) or is obtained as a residue of the distillation of crude oil (refined bitumen).
How long do bitumen driveways last? How long do asphalt driveways last? An asphalt driveway can last anywhere from 12 to 30 years before it needs repair work, comparable to concrete.
How much does a bitumen driveway cost?
The cost for asphalt driveways can range from $25.00 AUD per square meter to $55.00 per square meter. This depends on the thickness of asphalt required as well as how much preparation is needed for the area.
Can you put asphalt over old concrete? It is safe to pave asphalt over concrete. Concrete is a great base material because it is stable and allows for excellent compaction of the asphalt above. In fact, many miles of concrete roads are paved over with asphalt every year.
How long does a bitumen driveway last?
