Asphalt is a common material used in roadways, driveways, and parking lots due to its durability and flexibility. However, over time, even the strongest pavement can succumb to the forces of nature. Asphalt oxidation is a natural process where the material’s essential properties are gradually weakened due to exposure to oxygen, UV rays, and weathering.

The Role of UV Exposure in Asphalt Oxidation
Asphalt is particularly vulnerable to the sun’s ultraviolet (UV) radiation. UV rays trigger a chemical reaction in the asphalt binder, which holds the aggregate (stones and sand) together. This reaction causes the binder to lose its flexibility and become brittle, leading to cracking and eventual deterioration.
The impact of UV exposure is most evident during the summer months when the sun’s rays are the strongest. The intense heat speeds up the oxidation process, causing the pavement to age prematurely. Nova Scotia’s unique weather patterns, including hot summers and freezing winters, can exacerbate this issue, leading to significant wear and tear on asphalt surfaces.
The Combined Assault of Temperature and Moisture on Your Asphalt Driveway
Weathering, the process by which asphalt is broken down by environmental factors, is another significant contributor to pavement degradation. In Nova Scotia, the combination of heavy rainfall, snow, and fluctuating temperatures can wreak havoc on asphalt surfaces.
Water Infiltration
When water seeps into cracks in the pavement, it can freeze and expand during colder months, causing the cracks to widen and deepen. This process, known as freeze-thaw cycling, is particularly damaging in regions with harsh winters like Nova Scotia. Over time, repeated cycles can lead to potholes and extensive pavement damage.
Thermal Expansion and Contraction
Asphalt surfaces expand in hot weather and contract in cold weather. This constant movement can create stress within the pavement, leading to the formation of cracks. In Nova Scotia, where temperatures can vary dramatically between seasons, this thermal stress is a major factor in asphalt deterioration.
Signs of Asphalt Oxidation and Weathering
Recognizing the signs of asphalt oxidation and weathering can help you address issues before they become major problems. Some common indicators include:
• Fading Color: Fresh asphalt is dark black, but as oxidation progresses, the color fades to a dull gray. This is one of the earliest signs that your pavement is starting to degrade.
• Cracking: Small surface cracks may appear as the asphalt becomes brittle. If left untreated, these cracks can grow and allow water to penetrate, leading to further damage.
• Raveling: This occurs when the aggregate begins to separate from the binder, resulting in a rough, uneven surface. Raveling can make your pavement less safe for vehicles and pedestrians.
• Potholes: These are larger depressions in the pavement caused by the breakdown of the asphalt structure. Potholes can form quickly if minor damage is not repaired promptly.
Preventive Measures and Maintenance Strategies
Maintaining asphalt surfaces is essential to extend their lifespan and prevent costly repairs. Regular maintenance can mitigate the effects of UV exposure and weathering. Here are some effective strategies:
Sealcoating
Applying a protective sealcoat to your asphalt surface can help shield it from UV rays, water infiltration, and other environmental factors. Sealcoating enhances the appearance of your pavement and acts as a barrier against oxidation.
Crack Sealing
Addressing cracks as soon as they appear is crucial to preventing further damage. Sealing cracks can prevent water from seeping in and causing more extensive deterioration.
Regular Inspections
Periodic inspections can help identify early signs of oxidation and weathering. By catching problems early, you can take preventive action before they escalate.
