How Weather Affects Your Asphalt: What Every Property Owner Should Know

Asphalt is a durable and reliable paving material, but it is constantly exposed to the elements. From hot summer temperatures to freezing winter conditions, weather can have a major impact on the condition and lifespan of your asphalt.

Understanding how different weather conditions affect your pavement can help you recognize problems early and take the right steps to protect your investment.

How Hot Weather Affects Asphalt

During the summer, high temperatures can cause asphalt to soften. When asphalt becomes softer, heavy vehicles and frequent traffic can place additional stress on the pavement.

Over time, this can contribute to problems such as:

• Surface deterioration

• Rutting and depressions

• Cracking

• Uneven pavement

• Damage from heavy vehicle traffic

Parking lots and driveways that experience frequent vehicle traffic can be especially vulnerable during periods of extreme heat.

Regular maintenance can help protect the asphalt surface and prevent minor problems from becoming more serious.

Rain and Water Can Cause Major Asphalt Damage

Water is one of the biggest threats to asphalt pavement.

When asphalt develops cracks or other openings, rainwater can seep beneath the surface and reach the underlying base materials. Once water gets underneath the pavement, it can weaken the foundation and contribute to further deterioration.

Poor drainage can make the problem even worse. Standing water that remains on the pavement for extended periods can accelerate damage and create unsafe conditions.

Keeping drainage systems clear and repairing cracks promptly are two important ways to reduce water-related damage.

How Winter Weather Affects Asphalt

Cold temperatures can be particularly hard on asphalt, especially in areas that experience freezing and thawing.

When water enters small cracks in the pavement and temperatures drop below freezing, the water can freeze and expand. This puts pressure on the surrounding asphalt and can cause cracks to become larger.

When temperatures rise again, the ice melts and leaves space beneath the pavement. Repeated freezing and thawing can gradually weaken the pavement structure.

This process can eventually contribute to the formation of potholes.

Why Freeze-Thaw Cycles Cause Potholes

Potholes are often the result of a combination of water, temperature changes, and vehicle traffic.

A typical cycle may look like this:

Crack → Water enters → Water freezes and expands → Pavement weakens → Traffic causes further damage → Pothole develops

This is why it is important to address cracks before winter weather arrives. Small repairs can help prevent water from penetrating deeper into the pavement.

Snow and Ice Can Also Impact Asphalt

Snow itself does not necessarily damage asphalt, but the moisture associated with snow and ice can contribute to pavement problems.

Snowplows can also cause physical damage if pavement is already deteriorated or if plow blades catch raised or broken sections of asphalt.

De-icing products should also be used appropriately. Certain chemicals can affect pavement and surrounding surfaces, so following manufacturer recommendations is important.

Spring Weather Can Reveal Asphalt Problems

Spring is often when property owners begin noticing damage caused by winter.

As snow and ice melt, cracks, potholes, drainage problems, and areas of pavement deterioration may become more noticeable.

Spring is an excellent time to inspect your asphalt and identify areas that need attention.

Addressing damage early can help prevent it from becoming more expensive to repair later in the year.

How to Protect Your Asphalt From the Weather

While you cannot control the weather, you can take steps to reduce its impact on your pavement.

Seal Cracks Early

Crack sealing helps prevent water from entering the pavement through existing cracks. The sooner cracks are addressed, the less opportunity water has to reach the underlying materials.

Maintain Proper Drainage

Make sure water has somewhere to go. Clogged drains, blocked catch basins, and poor drainage can allow water to collect on your pavement.

Consider Sealcoating

Sealcoating can provide an additional layer of protection against water, sunlight, oxidation, and everyday wear. It can also improve the appearance of aging asphalt.

Repair Potholes Promptly

A small pothole can become significantly larger when exposed to continued traffic and moisture. Prompt repairs can help prevent further deterioration.

Schedule Regular Inspections

Regular pavement inspections allow you to identify problems before they become major repairs. A professional asphalt contractor can assess the condition of your pavement and recommend appropriate maintenance.

Protect Your Asphalt Year-Round

Every season presents different challenges for asphalt. Summer heat can soften pavement, rain can allow water to penetrate cracks, and winter freezing and thawing can contribute to potholes and structural damage.

The best way to protect your asphalt is to stay ahead of these problems with regular inspections and preventative maintenance.

If your driveway, parking lot, or commercial pavement is showing signs of cracking, potholes, fading, or drainage problems, don't wait for the damage to get worse.
