Weather plays a significant role in the performance and longevity of asphalt surfaces. Understanding how different weather conditions impact asphalt can help you take preventative measures to maintain the integrity of your paved surfaces. At Action Asphalt, we work year-round to ensure our clients get durable, long-lasting results despite weather challenges.
Effects of Hot Weather on Asphalt
1. Softening and Warping
High temperatures can cause asphalt to soften, which may lead to indentations, surface warping, or even rutting in areas with heavy traffic. When the asphalt becomes too soft, it loses its structural integrity, making it susceptible to damage.
2. Oxidation
Prolonged exposure to the sun’s UV rays can cause asphalt to oxidize, making it brittle and prone to cracking. This is why sealcoating is crucial to protecting the surface from the sun and extending its lifespan.
3. Expansion
In extreme heat, asphalt tends to expand. This expansion can cause stress cracks to form, weakening the surface over time and requiring repairs.
Effects of Cold Weather on Asphalt
1. Cracking
Cold weather causes asphalt to contract, which can lead to cracks, especially if the surface was already damaged or worn. These cracks can quickly become larger and lead to potholes if left untreated.
2. Freeze-Thaw Cycles
In areas with fluctuating temperatures, the freeze-thaw cycle is a significant concern. Water seeps into cracks, freezes, and expands, causing further cracking and deterioration of the asphalt. This is one of the primary causes of potholes during winter.
3. Heaving
Freezing ground can lead to frost heaves, where the asphalt surface lifts due to the expansion of moisture beneath it. This creates uneven surfaces and can significantly damage the integrity of the pavement.
Rain and Asphalt
1. Erosion
Heavy rainfall can erode the base layers of the asphalt, leading to settlement or sinking of the surface. This undermines the structural support, causing cracks and potholes to develop more quickly.
2. Water Damage
Standing water is one of asphalt’s biggest enemies. When water pools on the surface, it can penetrate through cracks and weaken the foundation. Over time, this leads to more significant structural damage.
Seasonal Asphalt Maintenance Tips
1. Summer Maintenance
- Sealcoating: Applying a protective sealcoat helps protect the asphalt from the sun’s harmful UV rays and reduces the risk of oxidation.
- Patching: Repair any indentations or ruts that form due to softening in the heat to prevent further deterioration.
2. Winter Maintenance
- Crack Sealing: Sealing cracks before winter helps prevent water from entering and expanding during freeze-thaw cycles.
- De-Icing: Use asphalt-safe de-icing solutions to reduce the risk of damage from snow and ice accumulation.
3. Year-Round Maintenance
- Drainage Solutions: Ensure proper drainage to prevent standing water on your asphalt surface.
- Regular Inspections: Schedule periodic inspections to catch and repair small issues before they become major problems.
