How Asphalt Pavement Reacts to Temperature Changes

How Asphalt Pavement Reacts to Temperature Changes


Asphalt pavement is a common and cost-effective material used for roads, parking lots, and driveways. However, its durability and longevity are significantly influenced by temperature changes. Understanding how asphalt reacts to different weather conditions is crucial for proper maintenance and ensuring a long-lasting surface.

How Temperature Affects Asphalt Pavement

Expansion and Contraction

Asphalt pavement, like most materials, expands and contracts with temperature fluctuations. During hot weather, the asphalt expands, leading to potential softening and deformation. Conversely, in cold weather, the asphalt contracts, which can result in cracks and other forms of damage.

Thermal Stress

Thermal stress refers to the internal stress within the asphalt caused by temperature changes. When temperatures fluctuate rapidly, the pavement can experience significant thermal stress, leading to damage such as cracking and potholing. This is especially problematic in regions with extreme temperature variations between day and night.

UV Radiation

UV radiation from the sun can degrade the asphalt binder, causing it to become brittle and lose its adhesive properties. This degradation process is accelerated during the summer months when UV exposure is at its peak. Over time, the pavement loses its flexibility and becomes more susceptible to cracks and other forms of damage.

The Importance of Sealcoating

What is Sealcoating?

Sealcoating is a protective layer applied to the surface of asphalt pavement to shield it from the damaging effects of UV radiation, water, and other environmental factors. It acts as a barrier, preventing moisture from penetrating the asphalt and causing damage. Sealcoating also enhances the appearance of the pavement, giving it a fresh, black finish.

Benefits of Sealcoating

  1. Protection from UV Damage: Sealcoating provides a protective barrier that shields the asphalt from harmful UV rays, preventing oxidation and extending the pavement's lifespan.
  2. Waterproofing: By sealing the surface, sealcoating prevents water from seeping into the asphalt, reducing the risk of damage caused by freeze-thaw cycles and water infiltration.
  3. Improved Durability: Sealcoating fills small cracks and imperfections, preventing them from expanding and causing further damage. It also strengthens the pavement, making it more resistant to wear and tear.
  4. Enhanced Appearance: A fresh coat of sealcoating gives the pavement a smooth, black finish, improving its overall appearance and curb appeal.

The Sealcoating Process

Inspection and Preparation

Before applying the sealcoat, a thorough inspection of the pavement is conducted to identify any existing damage or areas that require repair. This includes filling cracks, patching potholes, and cleaning the surface to ensure proper adhesion of the sealcoat.


Once the pavement is prepared, the sealcoat is applied using specialized equipment. The sealcoat is typically applied in two coats to ensure even coverage and maximum protection. The first coat is allowed to dry before the second coat is applied. The drying time may vary depending on weather conditions and the type of sealcoat used.


After the sealcoat is applied, it needs time to cure and harden. This process typically takes 24-48 hours, during which the pavement should be kept free from traffic and other disturbances. Once fully cured, the pavement is ready for use, with a fresh, protective layer that will enhance its durability and appearance.

Regular Maintenance and Inspection

Routine Inspections

Regular inspections are essential to identify any signs of damage or wear and tear on the asphalt pavement. This includes checking for cracks, potholes, and other forms of damage that may require immediate attention. Early detection and repair can prevent further deterioration and extend the lifespan of the pavement.

Scheduled Maintenance

In addition to routine inspections, scheduled maintenance is crucial to keep the asphalt pavement in optimal condition. This includes periodic sealcoating, crack filling, and patching to address any issues before they worsen. A well-maintained pavement not only looks better but also performs better, providing a smooth and safe surface for vehicles and pedestrians.
