When it comes to revamping the driveway of your property, the choice between concrete and asphalt is one that homeowners often grapple with. But what happens when you decide to transition from a concrete driveway to an asphalt one? At Affordable Road and Drive, we’ve encountered numerous clients considering this switch. In this article, we’ll delve into the importance of removing the existing concrete driveway before laying down asphalt.
1. Ensuring a Stable Base
Asphalt needs a stable, well-compacted base to function effectively. If you lay asphalt over an existing concrete driveway:
- The concrete driveway can shift over time, mainly if it needs to be laid correctly or if there’s movement in the ground beneath. This movement can cause the asphalt to crack or develop potholes.
- Concrete and asphalt expand and contract at different rates under various temperatures. This difference can lead to early wear and tear in the asphalt layer.
2. Drainage Concerns
Concrete surfaces typically have a more robust and less porous structure than asphalt:
- Water can get trapped between the concrete and asphalt layers, potentially leading to erosion or freeze-thaw damage during colder months.
- Proper drainage is essential to prolong the life of a driveway. By removing the concrete driveway first, asphalt contractors can ensure appropriate grading and drainage when laying down the new material.
3. Thickness and Durability
Asphalt’s durability is directly proportional to its thickness. When you lay asphalt over concrete:
- You’re restricted in how thick the asphalt layer can be, potentially reducing its lifespan.
- The bonding between concrete and asphalt can be inconsistent, leading to areas where the asphalt may wear away faster.
While it might seem cost-effective to lay asphalt over concrete in the short term, potential issues down the line can make it a more expensive option:
- Repairs, replacements, and addressing drainage issues can all accrue significant costs over time.
- Removing the concrete to start with a clean slate can offer better long-term value by reducing maintenance costs and prolonging the life of the asphalt driveway.
5. Aesthetics and Finish
For homeowners who care about the visual appeal of their property:
driveway laid over old concrete might have a different, smooth, consistent finish than asphalt is known for. Uneven areas, potential buckling, or discoloration can detract from the property’s overall appearance.
Making the Right Choice: Concrete vs. Asphalt Driveways
Choosing between concrete and asphalt for your driveway is crucial for both aesthetics and longevity. Here’s a snapshot:
- Climate Compatibility: Concrete performs better in hot climates, resisting deformation, while asphalt thrives in colder regions, managing freeze-thaw cycles and melting snow quickly due to its dark hue.
- Cost and Maintenance: Concrete has a higher initial cost but can last over 30 years with care. Asphalt is budget-friendly to start but may need regular maintenance, like seal coating, for a 20-year lifespan.
- Repairs: Concrete repairs can be a challenge in terms of colour and texture matching. In contrast, asphalt offers more seamless repairs, with seal coating rejuvenating its appearance.
- Aesthetics: Concrete boasts versatile design options, from staining to stamping. Asphalt traditionally is black, but tinted sealers now add colour variety.
- Environment: Concrete’s reflectivity reduces heat absorption, helping combat urban heat islands. Asphalt stands out for its recyclability, promoting sustainability by reusing old materials.
The transition from a concrete to an asphalt driveway is more than just laying one material over the other. For a long-lasting, durable, and aesthetically pleasing driveway, the existing concrete needs to be removed before laying down the asphalt.
