Asphalt surfaces, whether they are driveways, parking lots, or roads, are subject to a range of environmental stresses that can lead to deterioration over time. Cracks and potholes are among the most common and problematic issues, often resulting in costly repairs and potential safety hazards. Sealcoating is a preventive maintenance measure that plays a crucial role in extending the life of asphalt and mitigating the risks associated with cracks and potholes. We at Andersen Asphalt & Striping would like to further elaborate on this today.
Understanding Sealcoating Asphalt
Sealcoating involves applying a protective layer of sealant to the surface of asphalt. This sealant is typically made from a combination of coal tar or asphalt-based materials and is designed to form a durable, weather-resistant coating over the asphalt. The primary purpose of sealcoating is to shield the asphalt from harmful external elements, such as UV rays, water, and chemical spills.
Prevention of Asphalt Cracks
One of the primary ways sealcoating helps in preventing asphalt cracks is by providing a protective barrier against moisture. Water infiltration is a significant factor in the development of cracks. When water seeps into the porous surface of asphalt, it can freeze and expand during colder months, leading to the formation of cracks. These cracks can then widen over time, resulting in more severe damage. Sealcoating creates a non-porous layer that effectively blocks water from penetrating the asphalt surface. By preventing moisture infiltration, sealcoating reduces the risk of freeze-thaw cycles that contribute to cracking. Additionally, the sealcoat helps to prevent the oxidation of the asphalt binder, which can lead to brittleness and cracking as the binder loses its flexibility.
Prevention of Potholes
Potholes are another major concern for asphalt surfaces and often stem from the combination of cracks, water infiltration, and traffic wear. When cracks are not addressed, they can deepen and become more extensive, leading to the formation of potholes. These depressions are not only unsightly but can also pose a significant hazard to vehicles and pedestrians. Sealcoating helps in preventing potholes by maintaining the integrity of the asphalt surface. The sealcoat acts as a protective layer that minimizes the chances of cracks forming in the first place. Furthermore, by maintaining a smooth, continuous surface, sealcoating helps to distribute the weight of vehicular traffic more evenly, reducing the stress on the asphalt and decreasing the likelihood of pothole formation.
Enhancing the Durability of Asphalt
Beyond preventing cracks and potholes, sealcoating also enhances the overall durability of asphalt surfaces. The sealant used in the process contains additives that improve the flexibility and resilience of the asphalt. This added flexibility allows the surface to better withstand the stresses caused by traffic and temperature fluctuations.
Additionally, sealcoating helps to protect the asphalt from the damaging effects of ultraviolet (UV) rays. Prolonged exposure to sunlight can cause the asphalt to dry out and become brittle, leading to cracks and surface degradation. The sealcoat acts as a barrier against UV rays, preserving the asphalt’s flexibility and extending its lifespan.
