Driveways are an essential part of our homes, providing a safe and convenient space to park our vehicles. Over time, however, driveways can wear out and become cracked and damaged. When this happens, homeowners may start considering resurfacing options to refresh their driveway’s appearance and improve its functionality. One common question that arises in these situations is whether it’s possible to resurface a concrete driveway with asphalt. In this article, we will explore the feasibility of this option, examining the advantages, disadvantages, and necessary steps involved in resurfacing a concrete driveway with asphalt.
Advantages of Resurfacing with Asphalt:
1. Cost-effectiveness:
One of the major advantages of resurfacing a concrete driveway with asphalt is its cost-effectiveness. Compared to other resurfacing options, such as completely removing and replacing the concrete, asphalt resurfacing is significantly more affordable. This makes it an attractive option for homeowners looking to improve their driveway’s aesthetics and functionality without exceeding their budget.
2. Durability:
Asphalt is known for its durability, especially in high-traffic areas such as driveways. When properly installed and maintained, an asphalt surface can withstand heavy loads, resist cracking, and endure various weather conditions. This means that resurfacing your concrete driveway with asphalt can significantly increase its lifespan and reduce the need for frequent repairs.
3. Smooth and Seamless Finish:
Opting for an asphalt resurfacing allows homeowners to achieve a smooth and seamless finish for their driveway. Unlike concrete, which can develop unsightly cracks over time, asphalt provides a uniform appearance that enhances the curb appeal of your property.
Disadvantages of Resurfacing with Asphalt:
1. Height Difference:
One of the main challenges in resurfacing a concrete driveway with asphalt is the potential height difference. Since asphalt adds a layer over the existing surface, the level of the driveway may be slightly elevated. This height difference can create potential tripping hazards and may require adjustments to any adjacent structures or landscaping.
2. Limited Ability to Address Underlying Issues:
Resurfacing a concrete driveway with asphalt can improve its appearance and surface functionality. However, it is important to note that this option does not address any underlying issues within the concrete. If the driveway has extensive structural damage, such as severe cracking or settling, resurfacing alone may not provide a long-term solution.
Steps Involved in Resurfacing a Concrete Driveway with Asphalt:
1. Surface Preparation:
The first step in resurfacing a concrete driveway with asphalt is to prepare the existing surface. This typically involves thoroughly cleaning the driveway, removing any loose debris or vegetation, and repairing any visible cracks or potholes. Additionally, any oil stains should be treated to ensure proper adhesion of the asphalt layer.
2. Bonding Agent:
To improve the bond between the existing concrete and the asphalt, a bonding agent or tack coat is often applied. This substance helps ensure a stronger connection between the old and new surfaces, enhancing the overall durability and longevity of the resurfacing project.
3. Asphalt Overlay:
After the surface has been prepared and the bond coat has been applied, a layer of hot mix asphalt is spread over the driveway. Asphalt paving professionals utilize specialized equipment to ensure an even thickness and a smooth finish. The thickness of the asphalt layer depends on various factors, including the condition of the existing concrete and the expected traffic load.
4. Compaction and Curing:
Once the asphalt overlay has been applied, it is compacted using a roller or compactor to ensure proper density and compaction. This step helps eliminate any air pockets and creates a solid surface. After compaction, the asphalt layer needs time to cure. Typically, it is recommended to avoid driving on the newly resurfaced driveway for at least 24 to 48 hours to allow for sufficient hardening.Resurfacing a concrete driveway with asphalt can be a viable option for homeowners looking to enhance the appearance and durability of their driveway. By considering the advantages and disadvantages outlined in this article, along with following the necessary steps involved in the resurfacing process, homeowners can make an informed decision. However, it is always recommended to consult with asphalt paving professionals to assess the specific condition of the concrete driveway and determine the most suitable resurfacing approach.
