Asphalt pavement is built to endure, but the changing weather throughout the year can still take its toll. From the harsh freeze of winter to the UV rays of summer, each season presents unique challenges for asphalt driveways, parking lots, and roadways. Understanding how different weather conditions affect asphalt can help you take the right steps to protect your investment.
Spring
Spring brings the thawing of snow and ice, leading to pooling water on low spots of asphalt. As water sits on the surface, it slowly degrades the material. Below the pavement, thawing ground saturates the soil, increasing the risk of heaving and forming cracks and potholes. With the rainy season in full swing, water finds its way into every small crevice, further weakening the structure.
Prevention Tip: Regularly inspect and fill cracks in spring to prevent water infiltration and keep your pavement strong.
Summer
While summer often dries out the rain, it introduces another challenge—intense ultraviolet (UV) rays. UV exposure causes oxidation, which leads to the breakdown of lighter oils in the asphalt. Over time, the asphalt becomes brittle, making it more prone to cracking and surface damage.
Prevention Tip: Protect asphalt with a high-quality sealcoat to shield it from UV rays and maintain flexibility.
Autumn
Autumn is the ideal season for sealcoating asphalt, thanks to cooler temperatures that help the material cure properly. However, increased rainfall can pose challenges, as wet surfaces cannot be sealed. Falling leaves can also trap moisture on the pavement, keeping it wet and making sealcoating more difficult.
Prevention Tip: Keep the surface clear of leaves and debris to prevent trapped moisture and prepare for sealcoating.
Winter
Winter is the most damaging season for asphalt. Extreme cold causes the material to contract, creating tension that leads to cracks. Sudden temperature drops worsen the cracking, while freezing water expands inside the cracks, exacerbating the damage. Frost heave can also lift and deform the pavement, requiring significant repairs.
Prevention Tip: Apply a durable sealcoat before winter arrives and promptly repair any cracks to prevent water penetration.
