Arizona property owners may not have to shovel snow and scrape ice during the winter months, unlike in other parts of the country. However, rainfall, temperature swings, and crisp morning frost can still take a toll on asphalt surfaces. That’s why Arizona business owners shouldn’t overlook the impact that cooler weather can have on their parking lots.

The team at Sunrise Asphalt is here to help. In this article, we’ll discuss the importance of proactive asphalt maintenance before winter hits and share tips on how you can extend the life of your pavement, improve customer safety, and avoid costly repairs in the long run.

The Challenges of Winter in Arizona

Understanding the regional challenges that accompany Arizona winters is a first step toward proper asphalt maintenance.

Cooler temps at night and warmer weather during the day can put added stress on asphalt as it expands and contracts, especially if the asphalt already has some surface cracks.

Even light rainfall can be damaging. It can seep into small openings in the pavement and expand as the cool nighttime temps set in. That causes cracks in the pavement to spread, weakening the asphalt.

Dust and sand can also be a problem. Why? It can clog drain systems and can prevent proper drainage when rain does fall. That accelerates erosion and also creates unsafe conditions for drivers and pedestrians.

Is There Existing Damage?

Inspect the condition of your parking lot before the cooler weather arrives. Look for potholes, cracks, and areas where the asphalt looks faded or brittle. When exposed to the seasonal shifts in rainfall and temperature, these areas can quickly become larger problems.

It is also a good time to look for faded striping and pavement markings. Ensure that parking spaces, ADA-compliant areas, and crosswalks are clearly marked to minimize liability and enhance safety for both drivers and pedestrians.

Inspection checklist for asphalt maintenance:

  • Cracks (large or small): Even hairline cracks allow water to seep in and expand, leading to bigger problems in the long run.
  • Soft spots or potholes: These are signs of deeper structural issues that can worsen during the winter weather.
  • Surface wear: Areas that are brittle, faded, or rough indicate oxidation. 
  • Worn striping: Faded lines reduce visibility for both drivers and pedestrians and could put you out of ADA compliance.

Identify Drainage Issues

Ensuring proper drainage is a big part of asphalt maintenance. Even though Arizona doesn’t experience heavy winter storms, seasonal rainfall and lingering puddles can be damaging to asphalt if there are drainage issues.

Standing water can seep into cracks and weaken the asphalt, causing it to deteriorate over time. That leads to surface erosion, rutting, and potholes. It also creates unsafe conditions for pedestrians.

If you notice water collecting near curbs, at the low points of your lot, or around clogged storm drains and grates, these are indicators of drainage problems or even grading issues. It is important to address any concerns before the winter weather arrives.

Drainage checklist:

  • Be sure drains and grates are clear of dirt, sand, and debris.
  • After a rainstorm, check the parking lot for standing water, which could indicate clogged drains or grading issues.
  • Make sure that grading directs water toward drains and away from high-traffic areas.

Seal Coating and Crack Filling

Seal coating and crack filling can be effective ways to protect asphalt and prevent small areas of wear from turning into costly problems down the road. Sealcoating is a protective layer of oil that helps slow damage caused by water, oil, and UV rays. It is applied either by spray coating or squeegee coating.

Without this protection, asphalt fades, oxidizes, and becomes brittle, making it more vulnerable to cracking and surface wear.

If there are cracks in the asphalt, hot crack fill may be applied. Cracks are cleaned with gas-powered blowers and then filled with a hot rubber crack sealant. It stays pliable to help with the expansion and contraction of cracks.

Stay Ahead with Preventive Asphalt Maintenance

Waiting to address asphalt damage can be costly. Sealing cracks, refreshing striping, and fixing drainage issues save money in the long run. It also reduces liability by creating a safer parking lot for everyone.

Plus, you’re avoiding the scorching summer heat. Milder weather is ideal for asphalt maintenance. Crews can work more comfortably, and materials can cure more evenly.If your parking lot needs repair, Sunrise Asphalt is ready to help.
