Why You Should Remove a Concrete Driveway Before Laying Asphalt


Why You Should Remove a Concrete Driveway Before Laying Asphalt

If you’re planning to spruce up your old driveway, it may be tempting to simply lay asphalt on top of the existing concrete to give it a fresh look. However, this approach can lead to various issues in the long run. In this blog post, we will explore why you should remove a concrete driveway before laying asphalt. You’ll see why it’s the recommended approach for a successful and durable pavement installation.


Why You Should Remove a Concrete Driveway Before Laying Asphalt


1. Compatibility & Structural Integrity

A concrete driveway is constructed with expansion joints, allowing it to expand and contract with temperature changes. By overlaying asphalt directly onto the concrete, these expansion joints can become compromised, leading to cracks in the asphalt.

Moreover, concrete and asphalt are made from different base materials, which do not bond well together. This lack of compatibility can result in poor adhesion and reduced structural integrity of the new asphalt surface.


2. Long-term Cost Considerations

While laying asphalt directly over concrete might seem like a cost-saving measure initially, it can actually lead to more expenses in the future. Concrete has a tendency to crack over time due to factors such as freeze-thaw cycles, heavy loads, and natural settling.

When the underlying concrete cracks, it will eventually reflect on the surface of the asphalt, resulting in unsightly and uneven pavement. In the long run, you may find yourself needing to replace the entire pavement sooner than anticipated, incurring additional costs in the process.


3. Optimal Performance & Aesthetics

By removing the concrete driveway before installing asphalt, you can ensure optimal performance and enhance the overall appearance of your driveway. When the old concrete is removed, the base can be properly prepared, allowing for better compaction and improved drainage. This promotes a more stable foundation for the new asphalt, reducing the risk of future cracking and potholes.


Additionally, starting fresh with a clean slate allows you to address any underlying issues, such as poor drainage or inadequate support, resulting in a more durable and visually appealing driveway.


The Final Word

Removing the existing concrete driveway before laying asphalt is a prudent decision for several reasons. It preserves the structural integrity of the pavement, prevents compatibility issues, and helps avoid potential long-term costs associated with premature cracking and deterioration.
