How Water and Salt Damage Asphalt Through Cracks
Asphalt surfaces are an essential part of urban infrastructure, especially in cities like North Bay, Ontario. However, cracks in asphalt can lead to serious damage when exposed to water and salt. Understanding this process is key to maintaining durable, safe pavements.
Introduction to Asphalt Cracks and Their Vulnerability
Asphalt is designed to be a resilient material capable of withstanding heavy traffic and varying weather conditions. Still, over time and with constant exposure to environmental factors, cracks inevitably form. These cracks, though sometimes appearing minor, can expose the underlying layers to damaging agents such as water and salt.
In North Bay, where seasonal changes bring freezing temperatures and significant snowfall, salt application on roads and parking lots is common to melt ice. Unfortunately, this practice can accelerate asphalt deterioration if cracks are present.
How Water Penetrates Asphalt Cracks
Water is one of the most damaging elements when it comes to asphalt maintenance. When water seeps into cracks, it penetrates the base layers beneath the asphalt surface. This infiltration causes several issues:
- Freeze-Thaw Cycles: Water trapped in cracks freezes during cold weather, expanding and causing the cracks to widen and deepen.
- Base Layer Erosion: Constant moisture weakens the base material, leading to settling and uneven surfaces.
- Loss of Structural Integrity: As cracks grow, the asphalt loses its ability to support weight, resulting in potholes and further damage.
The Role of Salt in Asphalt Deterioration
Salt is widely used for ice control in North Bay, but it can be a double-edged sword when it comes to asphalt longevity. Salt accelerates the damage caused by water in several ways:
Salt’s Chemical Effects
Salt lowers the freezing point of water, which means water trapped in cracks remains liquid longer and continues to seep deeper. Additionally, salt can degrade the asphalt binder, the glue that holds the asphalt together, weakening the surface over time.
Increased Freeze-Thaw Damage
With salt present, freeze-thaw cycles become more frequent and severe, rapidly expanding cracks and making repairs more urgent.
