Maintaining asphalt in arid conditions, such as those experienced in Arizona, comes with its own challenges. The intense heat, low humidity, and occasional dust storms can impact asphalt surfaces. As Sunrise Asphalt is a leading asphalt company committed to ensuring the longevity and performance of paved surfaces, we’ve compiled a comprehensive guide on tips for proper asphalt maintenance in the particularly arid conditions of Arizona.


7 Tips for Proper Asphalt Maintenance

1. Regular Inspection and Cleaning:

In Arizona’s arid climate, dust and debris accumulation on asphalt surfaces are common. Regular inspection and cleaning are fundamental steps in maintaining asphalt integrity. Dust and debris can trap moisture, contributing to premature deterioration. Thorough cleaning with a power broom or street sweeper helps to remove debris and prevent the formation of pockets where water can collect.


2. Crack Sealing:

Cracks in the asphalt may start small but can quickly escalate into more significant issues, especially in arid conditions. The intense heat and UV exposure in Arizona can accelerate the drying and aging of asphalt, leading to the development of cracks. Prompt crack sealing is crucial to prevent water penetration, which can further compromise the pavement’s structural integrity. Utilizing high-quality crack sealants ensures a resilient and long-lasting repair.


3. Sealcoating for UV Protection:

The Arizona sun can be relentless, causing asphalt surfaces to become brittle and lose their flexibility over time. A protective sealcoat acts as a barrier against UV rays, helping maintain the asphalt’s flexibility and extend its lifespan. Sealcoating also provides an added layer of defense against oxidation and chemical spills, common challenges in arid environments.


4. Temperature-Appropriate Asphalt Mixes:

Choosing temperature-appropriate asphalt mixes is essential when undertaking new asphalt projects or repairs. Arizona’s extreme temperatures, especially in summer, demand asphalt mixes with high resistance to heat-induced deformations. Working with asphalt mixes designed for hot climates ensures that the pavement can withstand temperature extremes without compromising its structural integrity.


5. Adequate Drainage Solutions:

While Arizona is generally arid, occasional intense rainfall events can occur. Proper drainage is essential to prevent water accumulation and subsequent damage to the asphalt surface. Ensuring that the pavement is properly sloped and that drainage systems are in place helps redirect water away from the surface, reducing the risk of erosion and water-related issues.


6. Timely Repairs and Resurfacing:

Addressing pavement issues promptly is critical in arid conditions. Minor cracks and surface distress can escalate rapidly due to the combination of heat and occasional weather extremes. Timely repairs, such as patching and resurfacing, prevent small issues from becoming major headaches. Regular pavement evaluations by professionals can help identify potential problems before they escalate.


7. Traffic Management:

Heavy traffic loads, especially in urban areas, can accelerate wear and tear on asphalt surfaces. Implementing traffic management strategies, such as diverting heavy vehicles during peak temperatures or using temporary surfaces during construction, can help minimize stress on the asphalt. This proactive approach contributes to the long-term sustainability of the pavement.


Proper asphalt maintenance in the arid conditions of Arizona is a proactive and strategic thing. By incorporating regular inspections, appropriate cleaning, crack sealing, sealcoating, and choosing temperature-appropriate mixes, stakeholders can ensure the durability and longevity of asphalt surfaces. Embracing these tips, along with timely repairs, adequate drainage solutions, and effective traffic management, will protect asphalt from the challenges of Arizona’s arid climate and contribute to sustainable and resilient pavement infrastructure for years to come.
