Water damage is one of the primary culprits behind the deterioration of asphalt surfaces, causing cracks, potholes, and overall structural degradation. Sealcoating plays a crucial role in preventing water damage to asphalt, acting as a protective barrier that shields the surface from the harmful effects of moisture infiltration. Today, we at Andersen Asphalt & Striping would like to discuss the role of sealcoating in preventing water damage to asphalt.
Why are Freeze Thaw Cycles Bad for Asphalt
Asphalt is naturally porous, allowing water to penetrate its layers and reach the underlying base. When water seeps into the asphalt, it can initiate a destructive cycle, particularly in regions with varying temperatures. During freeze-thaw cycles, water that has permeated the asphalt expands as it freezes, exerting pressure on the surrounding material. This process creates cracks and weakens the structural integrity of the asphalt.
Protective Benefits of Sealcoating Asphalt
Sealcoating acts as a waterproofing agent, forming a protective layer on the surface of the asphalt. This impermeable barrier prevents water from infiltrating the asphalt and reaching the underlying layers, thereby mitigating the risks associated with freeze-thaw cycles. The application of a high-quality sealcoat creates a smooth, even surface that repels water and prevents it from seeping into the asphalt matrix. Also, sealcoating enhances the asphalt’s ability to resist the harmful effects of standing water. Puddles and stagnant water on asphalt surfaces can lead to a host of issues, including surface erosion, accelerated wear, and the formation of potholes. Sealcoating ensures proper water runoff by promoting a more even surface, reducing the likelihood of water pooling and its associated problems. Beyond freeze-thaw cycles and standing water, sealcoating also guards against the damaging impact of rain and moisture in general. Rainwater, if left unchecked, can gradually erode the top layer of asphalt, leading to the formation of small cracks that can escalate into more significant issues over time. Sealcoating acts as a shield against this process, extending the lifespan of the asphalt and minimizing the need for costly repairs. In addition to its protective qualities, sealcoating contributes to the overall resilience of asphalt against environmental elements. Ultraviolet (UV) rays from the sun can accelerate the aging process of asphalt, causing it to become brittle and prone to cracking. A quality sealcoat reflects UV rays, reducing the extent of sun damage and maintaining the asphalt’s flexibility.
Routine Asphalt Maintenance
Regular maintenance and timely application of sealcoating are essential to sustaining these protective benefits. Over time, the sealcoat may wear off due to traffic, weather conditions, and other external factors. Therefore, a proactive approach to sealcoating, with periodic reapplications, is vital to ensuring continued protection against water damage and other environmental stresses.
