Concrete is a potential alternative to traditional asphalt surfaces and is often used in sidewalks and access routes, providing remarkable durability in heavy-duty areas.
When deciding between a concrete or asphalt parking lot or large pavement surface, you should consider:
- Durability: Concrete has a longer lifespan than asphalt. You can expect concrete to last 30-40 years, while asphalt lasts about 20-25 years. When asphalt parking lots have reached their lifespan, they can often be repaved, reusing the sub-base.
- Climate: Asphalt withstands cold temperatures better than concrete. However, concrete withstands extreme temperatures, while asphalt can become hot and oily.
- Stains: Asphalt tends to hide oil, gas and rust stains better than concrete.
- Maintenance: Because concrete has joints to withstand expansion and contraction, it requires little maintenance beyond cleaning and joint filling. While asphalt is easier to repair than concrete when it does crack, asphalt deteriorates faster, requiring more frequent.
- Time to cure: Asphalt can be driven on a couple days post-installation, but concrete will require at least a week.
- Price: Concrete will last longer, but in general, it costs nearly double the price to install and repair.
Regardless of which material you choose to use, proper installation and a regular maintenance schedule will help ensure the longevity of your parking lot.
