Asphalt can be paved over concrete if the base is structurally sound and properly prepared, but specific precautions must be taken.
Potential Problems
- Concrete expansion joints can reflect through the asphalt surface.
- Uneven or cracked concrete weakens new layers.
- Poor bonding between materials causes premature failure.
How to Do It Right
- Inspect and repair any cracks or soft spots in the concrete first.
- Apply a tack coat for better adhesion between layers.
- Overlay with sufficient asphalt thickness to prevent joint reflection.
When installed correctly, asphalt-over-concrete driveways perform well and offer a clean, renewed appearance.
