Use Asphalt as pavement is one of the most durable and cost-effective materials for driveways, roads, and parking lots. But under the intense Arizona sun, even this strong material has its limits. In Tucson and Phoenix—where scorching temperatures and relentless UV rays dominate the climate—proper maintenance becomes crucial to extend the life of your paved surfaces.
At APS Chipsealing & Asphalt Paving, we specialize in helping homeowners, property managers, and business owners protect their asphalt investments from Arizona’s extreme conditions. Here’s a deep dive into how sun and heat impact your pavement and what you can do to prevent long-term damage.
How Heat Affects Asphalt Pavement
Arizona summers are no joke. With daytime temperatures often exceeding 100°F, asphalt surfaces absorb and retain a significant amount of heat, which can lead to a number of structural problems:
1. Softening and Warping
Hot mix asphalt is designed to handle high temperatures, but even the toughest blends can begin to soften when the pavement is constantly exposed to extreme heat. This can cause warping, rutting, and surface deformities—especially in high-traffic areas like commercial parking lots.
2. Surface Cracking
As the asphalt heats up, it expands, and when it cools at night, it contracts. This daily cycle of expansion and contraction places stress on the surface, leading to cracks that widen over time if left untreated.
UV Rays: The Silent Asphalt Destroyer
It’s not just the heat you need to worry about—the sun’s ultraviolet (UV) rays also wreak havoc on unprotected asphalt:
1. Oxidation
UV rays cause oxidation, a chemical reaction that causes the asphalt binder to break down. Over time, the pavement becomes brittle and loses flexibility, which accelerates surface deterioration.
2. Color Fading
That rich, deep blacktop look fades fast under direct sunlight. Faded asphalt not only looks unattractive but also signals surface wear and potential internal damage.
Why These Effects Are Worse in Tucson and Phoenix
Because of the arid desert climate, asphalt in Arizona faces unique challenges:
-
Year-round sun exposure with little rain means longer UV damage cycles.
-
High ground temperatures push the limits of the asphalt’s softening point.
-
Sudden summer monsoons can seep into small cracks, then evaporate quickly, worsening the damage.
These conditions make it essential to choose reputable pavement contractors who understand Arizona’s climate and use the proper materials and techniques to protect your investment.
