Sealcoating is more than just a cosmetic touch-up for asphalt surfaces; it’s a scientifically designed process that plays a crucial role in safeguarding the integrity and longevity of these surfaces. The science behind sealcoating is rooted in its ability to create a robust protective barrier that shields asphalt from the harsh effects of weather, chemicals, and everyday wear and tear. At its core, sealcoating is a preventive maintenance technique that involves applying a specially formulated coating to the surface of asphalt. This coating, typically made of either coal tar or asphalt emulsion, is designed to adhere tightly to the asphalt, forming a durable shield that acts as a barrier against external elements. With this in mind, we at Andersen Asphalt & Striping would like to discuss the science involving sealcoating.
Protection from Water
One of the primary threats that asphalt faces is water penetration. Water can seep into small cracks and crevices on the surface, eventually infiltrating the underlying layers and causing erosion. This is where sealcoating steps in. The sealant creates a waterproof layer, preventing water from entering the asphalt and safeguarding it against moisture-related deterioration, such as freeze-thaw cycles.
Safeguarding Asphalt from Sun Damage
The sun’s ultraviolet (UV) rays can wreak havoc on asphalt surfaces, causing oxidation that leads to fading, brittleness, and cracking. Sealcoating contains UV-resistant additives that effectively shield the asphalt from these harmful rays, maintaining its color and flexibility over time.
Defense from Chemical Exposure
Chemical exposure is another significant threat, particularly in areas with high vehicle traffic. Gasoline, oil, and other chemicals can cause asphalt to weaken and break down. Sealcoating acts as a barrier against these chemicals, preventing them from seeping into the asphalt and causing damage.
Science Behind Sealcoating
The science behind the application process is equally important. Before sealcoating, the surface must be cleaned thoroughly to ensure proper adhesion. Any existing cracks or potholes are filled and repaired to create a smooth surface. This meticulous preparation ensures that the sealcoating material adheres uniformly, providing consistent protection across the entire surface. The thickness of the sealcoating layer is also carefully calculated. Applying a coat that is too thick can lead to cracking, while a coat that is too thin may not provide adequate protection. Professionals utilize their expertise to apply the optimal thickness, ensuring that the protective layer is just right for the specific surface.

In a nutshell, the science behind sealcoating revolves around its ability to create a resilient barrier against the elements that threaten the integrity of asphalt surfaces. By preventing water infiltration, blocking UV rays, and resisting chemical damage, sealcoating extends the lifespan of asphalt and reduces the need for costly repairs or replacements. The meticulous preparation and precise application of sealcoating materials further enhance its effectiveness, making it a vital tool in asphalt maintenance. So, the next time you see a freshly sealcoated asphalt surface, remember that beneath its smooth appearance lies a scientifically designed shield that’s working tirelessly to preserve its strength and functionality.
