When your asphalt starts showing cracks in Jacksonville, it’s natural to wonder if paving over it is a viable solution. The answer is not always straightforward, as it depends on several factors including the extent of damage, the underlying cause of the cracks, and your budget.
## Understanding Asphalt Cracks in Jacksonville
Jacksonville’s unique climate with hot summers, occasional freezing temperatures, and significant rainfall creates particular challenges for asphalt. The expansion and contraction from temperature fluctuations, combined with water penetration, often lead to cracking over time.
Before deciding to pave over cracked asphalt, it’s important to determine what type of cracks you’re dealing with:
Alligator cracks, which resemble the skin of an alligator, usually indicate structural failure beneath the surface.
Linear cracks might suggest normal aging or minor settlement issues.
Block cracks typically form rectangular patterns and often result from shrinkage.
Edge cracks appear along the perimeter where the asphalt meets the ground.
## When You Can Pave Over Existing Asphalt
Yes, you can pave over cracked asphalt in Jacksonville under certain conditions. This process, known as an overlay, involves adding a new layer of asphalt over the existing surface. It works well when:
The existing asphalt is still structurally sound despite surface cracks.
The cracks are minor and limited to the surface layer.
The base and subgrade remain intact and properly drained.
Overlays typically cost less than full replacement and can extend your pavement’s life by 8-15 years when done correctly.
## When Paving Over Isn’t Recommended
Sometimes paving over cracked asphalt isn’t the right solution, particularly when:
The cracks indicate deep structural problems.
Water is pooling or draining improperly beneath the surface.
The asphalt has significant depressions or potholes.
Multiple previous overlays have already been applied.
Ignoring these warning signs and simply paving over severely damaged asphalt often leads to the new layer developing the same problems within a short time, wasting your investment.
## Proper Preparation Is Key
If an overlay is appropriate for your situation, proper preparation makes all the difference:
Smaller cracks should be cleaned and filled.
Larger damaged areas may need to be cut out and patched.
The entire surface requires thorough cleaning.
A tack coat should be applied to ensure proper bonding between old and new asphalt.
## Jacksonville Weather Considerations
Jacksonville’s climate requires special attention when planning asphalt work. The high humidity and frequent rain can affect both the installation process and long-term performance. Properly installed drainage systems are crucial to prevent water damage to your new asphalt overlay.
We recently completed an overlay project near Talbot Island where the existing asphalt was showing significant wear from salt exposure and tourist traffic. With proper preparation and quality materials, the new surface is holding up beautifully against the coastal elements.
If you’re dealing with cracked asphalt in Jacksonville, it’s best to consult with professionals who understand local conditions.
