01
How long does new asphalt paving last in Fredericton's climate?
In our 37 years of experience, a professionally installed asphalt surface in Fredericton can last 20 to 30 years. The key to achieving this lifespan is proper installation from the ground up. This includes meticulous sub-base compaction to create a stable foundation, ensuring correct grading for water drainage, and using high-quality hot mix asphalt. Regular maintenance is also crucial for asphalt lifecycle extension. We recommend applying a protective sealcoat every 2-3 years, after the initial curing period, to create a waterproof barrier against our harsh freeze-thaw cycles. This simple step in your pavement maintenance schedule prevents water from penetrating the surface, which is the primary cause of cracks and potholes.
02
What causes potholes and how do you repair them properly?
Potholes are primarily caused by water penetrating the asphalt surface and weakening the sub-base. During Fredericton's winters, this trapped water freezes and expands, pushing the pavement up. When it thaws, it leaves a void, and the weight of traffic causes the weakened asphalt to collapse, creating a pothole. A proper repair is more than just filling the hole. Our process involves cutting a clean, rectangular perimeter around the damaged area to remove all compromised material. We then excavate the failed sub-base and replace it with new, compacted aggregate. Finally, we apply hot mix asphalt in layers, ensuring each layer is fully compacted to create a permanent patch that is level with the surrounding surface.
03
Should I repair or completely resurface my driveway?
The decision to repair or resurface depends on the foundation's integrity. If you have a few isolated potholes or cracks but the rest of the driveway is stable and not extensively cracked (known as alligator cracking), targeted asphalt paving & repair is the most cost-effective solution. However, if more than 25-30% of the surface is damaged with widespread cracking, but the sub-base is still solid, resurfacing is a great option. This involves grinding off the top layer of old asphalt and applying a new HL3 topcoat. If your driveway has major issues like deep ruts, significant sinking, or extensive alligator cracking, it indicates a failed driveway foundation, and a full removal and replacement is necessary to ensure long-term results.
04
How often should I seal coat my asphalt parking lot or driveway?
We recommend applying the first sealcoat one year after a new installation to allow the asphalt to fully cure and harden. After that, a consistent pavement maintenance schedule of resealing every 2 to 3 years is ideal for the Fredericton climate. Sealcoating serves two critical functions: it creates a waterproof barrier to stop water infiltration and freeze-thaw damage, and it protects the asphalt binder from oxidizing and becoming brittle due to sun and air exposure. This preventative measure is one of the most effective ways to maximize your investment, significantly contributing to asphalt lifecycle extension and delaying the need for more costly asphalt paving & repair work down the road.
05
What is the best time of year for asphalt work in Fredericton?
The optimal season for asphalt paving & repair in Fredericton is from late spring through early fall, typically from May to October. Asphalt work requires warm, dry conditions for the material to be properly installed and cured. The ground should not be frozen, and ambient air temperatures should consistently be above 10 degrees Celsius. Paving in colder weather prevents the hot mix asphalt from being compacted correctly before it cools, leading to a weaker, more porous surface that is susceptible to premature failure. We schedule all our projects during this window to guarantee the highest quality and durability for your new pavement.
06
What is the difference between HL8 and HL3 asphalt mixes?
Using the right type of asphalt is critical for durability, and we use a two-layer system for superior results. HL8 is a basecoat mix. It contains larger aggregate (stones) and is designed for strength and stability. We use it as the foundational layer of pavement because it provides excellent load-bearing capabilities. HL3, on the other hand, is a topcoat or surface mix. It has a finer aggregate, creating a denser, smoother, and less permeable finish. This smooth surface is more resistant to water penetration and provides a clean, attractive appearance. By combining a strong HL8 base with a durable HL3 topcoat in our asphalt paving & repair projects, we build surfaces that are both structurally sound and built to last.
