How Weather Affects Asphalt and Concrete (And What Contractors Recommend)

Asphalt and concrete are two of the most common materials used for driveways, parking lots, sidewalks, and patios. Both are strong and long-lasting, but weather plays a big role in how well they hold up over time. Hot sun, heavy rain, and freezing temperatures can damage surfaces, especially when they are not taken care of properly. Knowing how the weather affects these materials can help you keep your pavement in great shape.

Heat Can Cause Cracking

In hot weather, asphalt gets soft and flexible. While this can help it absorb weight, too much heat can cause it to weaken and form small cracks. These cracks may seem small at first but can spread when vehicles drive over them. Heat can also make concrete expand. When the surface cools later at night, it shrinks. This constant expanding and shrinking causes stress and may lead to cracks and rough spots.

Cold Weather Brings Freeze-Thaw Damage

Cold weather is tough on both asphalt and concrete. When water gets into small cracks and freezes, it expands and breaks the material apart. This is called freeze-thaw damage, and it is one of the most common reasons driveways and sidewalks start to crumble in winter climates. Areas that freeze overnight and warm up during the day are at higher risk.

Rain and Moisture Erosion

Heavy rain and moisture can weaken pavement as well. Water can wash away the base layer under asphalt or concrete, causing the surface to sink or form potholes. On concrete surfaces, water carries chemicals that seep into the material, slowly wearing it down. Standing water is especially harmful, which is why good drainage is so important.

What Contractors Recommend

Contractors agree that regular maintenance goes a long way. Sealing asphalt every few years keeps heat and water from causing damage. Concrete benefits from sealing too, especially if it is stamped or decorative. Keeping cracks sealed early stops moisture from turning into bigger problems. Good drainage and proper installation are also key to long-term strength.
