Asphalt sealcoating is a powerful protector, extending pavement life by sealing the surface against relentless harsh elements. This technique works through a simple yet effective process, creating a robust shield to prevent water infiltration, UV damage, and wear from vehicular traffic. The science of sealcoating is essential in preserving the integrity and longevity of our roads and driveways, ensuring they remain smooth and durable for years to come.
Prevents Water Infiltration
When it rains or when snow melts, water can seep into the small cracks and crevices in the asphalt surface. This water infiltration is problematic as it can penetrate the pavement layers and erode the structural foundation. As water infiltrates and freezes during cold weather, it expands, exerting pressure on the pavement that causes cracks to widen. These widened cracks weaken the asphalt, creating entry points for more water infiltration, perpetuating the damage cycle.
Asphalt sealcoating acts as a protective barrier against water infiltration. It is a liquid emulsion composed of asphalt, aggregate, and other additives, which is applied evenly over the asphalt surface. Once it cures, the sealcoat forms a waterproof membrane to seal off the pores and imperfections in the pavement. This impermeable layer effectively repels water, preventing it from seeping into the asphalt and causing damage.
Shields against UV Damage
Asphalt contains binders that hold the aggregate together. When exposed to UV radiation, these binders begin to break down. Sealcoating acts as a protective shield against this harmful UV radiation. It forms a durable, weather-resistant layer on the pavement, effectively blocking the sun’s UV rays from directly impacting the asphalt.
Sealcoating prevents premature aging and deterioration of the pavement by creating this protective barrier. It inhibits the penetration of harmful substances like oil, gas, and water into the asphalt, which can exacerbate UV damage.
Resists Wear from Vehicular Traffic
As vehicles traverse over asphalt surfaces, they subject the pavement to various stressors. These include the abrasive action of tires and the weight of the vehicles, both of which can wear down the asphalt over time. Sealcoating forms a resilient barrier, effectively resisting the forces vehicles exert on the pavement.
When applied, asphalt adheres to the existing asphalt surface and dries to form a tough, protective layer. This layer minimizes the impact of traffic-induced stress, preventing cracks, oxidation, and water infiltration, which can further weaken the pavement structure. Asphalt sealcoating acts as a durable armor, shielding the underlying asphalt from the relentless assault of vehicular traffic.
Fills Surface Cracks and Voids
Surface cracks are visible splits or fractures in the asphalt. They can allow water to penetrate the pavement, leading to further damage. Voids are empty spaces or gaps within the asphalt. They weaken the structural integrity of the pavement and can worsen over time.
Sealcoating involves applying a protective layer of sealant over the surface. The sealant, made of coal tar or asphalt-based materials, effectively seals the cracks and fills the voids. This active intervention prevents moisture and other harmful substances from infiltrating the pavement, preserving its strength and longevity.
