If you have an existing asphalt driveway or walkway that is worn out, cracked, or just in need of a facelift, you might be wondering if you can install pavers over the asphalt. The short answer is yes, it is possible to install pavers over asphalt. However, there are several factors to consider before embarking on this project.
Assess the Condition of the Asphalt
Before installing pavers over asphalt, it is crucial to assess the condition of the existing surface. Pavers are a solid and durable option, but they rely on a stable base for longevity and performance. If the asphalt is severely cracked, crumbling, or sinking, it is not recommended to install pavers over it. In such cases, it is better to remove and replace the asphalt before installing the pavers.
Stability and Drainage
One of the primary concerns when installing pavers over asphalt is ensuring stability and proper drainage. An asphalt base may not provide the same stability as a compacted aggregate base, which is typically recommended for paver installations. Therefore, you need to evaluate whether the existing asphalt is sufficiently stable to support the weight and movement of the pavers. Additionally, it is vital to ensure that the surface graded away from the home or other structures to prevent water from pooling.
Preparing the Asphalt Surface
Once you have determined that your existing asphalt is in good condition to support pavers, thorough preparation of the surface is crucial. Begin by cleaning the asphalt surface of debris, dirt, and oil stains. A pressure washer can be effective in removing these substances. Next, it is important to repair any cracks or potholes in the asphalt. Use a crack filler or patching compound to seal these imperfections and create a smooth surface.
Applying a Bedding Layer
A bedding layer is typically required for installing pavers over asphalt. This layer serves as a cushion between the pavers and the asphalt, providing a level surface and aiding in the distribution of weight. Common materials used for the bedding layer include sand, crushed stone, or an aggregate mix. Spread the bedding layer evenly and level it using a rake or compactor to ensure a solid and stable base.
Installing the Pavers
With the asphalt surface prepared and the bedding layer in place, you are ready to install the pavers. Carefully lay the pavers in the desired pattern, starting from the designated edge. Use a level to ensure that the pavers are aligned and have a consistent height. Gaps between the pavers can be filled with sand or polymeric jointing sand for added stability and prevention of weed growth.
Consider Seeking Professional Help
While it is possible to install pavers over asphalt as a DIY project, it can be a complex task, especially for larger areas or if you have limited experience with such installations. Hiring a professional paver contractor can ensure a smooth and secure installation, minimizing the chances of future problems.
Regular Maintenance and Care
Once the pavers are installed, it is essential to provide regular maintenance and care to keep them in good condition. This includes regular sweeping and power washing to remove dirt and debris, periodic resealing to protect the pavers, and repairing any damaged or loose pavers to maintain the integrity of the surface.
Installing pavers over asphalt can be a viable option to revamp worn-out or damaged surfaces. However, thorough assessment, preparation, and proper installation techniques are crucial for a successful and long-lasting outcome. If you are unsure about the suitability or complexity of the project, it is recommended to consult with a professional paver contractor before proceeding.
