How Water and Salt Damage Asphalt Through Cracks
Asphalt pavements are a vital part of infrastructure in cities like Barrie, Ontario. However, water and salt can severely damage asphalt through cracks, leading to costly repairs. Understanding this process is key to proper maintenance and longevity.
Introduction to Asphalt Damage in Barrie
Barrie, a top 30 city in Ontario, experiences seasonal changes that can accelerate asphalt deterioration. One of the most common problems is the infiltration of water and salt through cracks. This issue not only compromises the surface but also the structural integrity beneath.
How Water Penetrates Asphalt Cracks
Water is one of the primary culprits in asphalt degradation. When cracks form, water seeps inside and creates several problems:
- Freeze-Thaw Cycles: Water trapped in cracks freezes during winter, expanding and widening the cracks.
- Base Erosion: Water weakens the base material beneath the asphalt, causing settling and more cracks.
- Surface Softening: Prolonged moisture exposure leads to softening and loss of asphalt binder, reducing durability.
The Role of Salt in Asphalt Damage
In Barrie’s winter months, salt is commonly used for de-icing roads and parking lots. While effective at melting ice, salt accelerates asphalt damage in cracked areas by:
- Lowering the freezing point of water, increasing freeze-thaw cycles.
- Breaking down asphalt binders chemically, reducing flexibility.
- Increasing corrosion of underlying metal reinforcements or drainage pipes.
Why Crack Maintenance is Critical
Ignoring cracks allows water and salt to penetrate deeper, accelerating deterioration. Regular maintenance by experts like Capital Parking Lot Line Painting in Barrie can prevent costly repairs and extend asphalt life.
