Protecting Pavement with Smart Summer Asphalt Maintenance Strategies
When the summer heat hits hard, it doesn’t just affect people—it affects your pavement too. High temperatures and prolonged UV exposure can quickly break down the integrity of asphalt, leading to costly damage that’s often preventable. Whether you manage a commercial lot, industrial yard, or public roadway, understanding the impact of heat and implementing a solid summer asphalt maintenance plan is critical to protecting your investment.
How Heat Affects Asphalt
Asphalt is a flexible material by design, but excessive heat can compromise that flexibility. During the summer, surface temperatures can reach 50°C or more in parts of Ontario—hot enough to soften standard asphalt. When the pavement becomes too soft, it can deform under the pressure of vehicles, especially heavy trucks or equipment. This softening is often accompanied by oxidation, which dries out the binding agents in asphalt, leading to cracks, fading, and brittleness. This is known as asphalt sun damage, and it’s one of the leading causes of early pavement deterioration during the summer months.
Signs of Heat-Related Pavement Issues
Be on the lookout for these red flags:
- Surface depressions or rutting in drive lanes and high-traffic areas
- Soft, sticky areas during peak afternoon heat
- Cracks forming in clusters, especially where water may have seeped in
- Color fading, which indicates surface oxidation
- Loose aggregate or crumbling edges
Even small signs of distress can quickly evolve into larger, more expensive issues if ignored.
6 Proactive Summer Asphalt Maintenance Tips
Implement these proven strategies to reduce the impact of extreme heat:
1. Install Heat-Resistant Asphalt Mixes
When paving or resurfacing, opt for heat-resistant asphalt blends. These specialized formulations are designed with polymers or additives that improve elasticity and thermal resistance. Not only do they resist rutting and softening, but they also maintain structural integrity longer under heavy use.
2. Routine Surface Inspections
Schedule monthly inspections during peak summer to catch early signs of stress. Look for micro-cracks, oil stains, and soft spots. A trained paving professional can often identify problems you might miss and recommend targeted repairs before they escalate.
3. Sealcoating as a Shield
Sealcoating acts like sunscreen for asphalt. It reflects UV rays, seals in the binding oils, and keeps the surface looking sharp. For properties exposed to high sun and traffic, this treatment can extend pavement life by 3–5 years. It’s also one of the best defenses against asphalt sun damage.
4. Keep Water Flow in Check
Water that collects on a heated surface quickly penetrates micro-cracks and weakens the sub-base. Poor drainage leads to potholes, heaving, and failure beneath the surface. Make sure catch basins are functioning properly, and grading slopes away from structures and travel lanes.
5. Limit Heavy Traffic During Peak Hours
The hottest time of day (typically noon to 4 p.m.) is when asphalt is at its most vulnerable. If possible, restrict garbage trucks, freight deliveries, or construction traffic to cooler parts of the day. In large industrial zones, consider designating alternate summer load zones.
6. Patch and Repair Promptly
Even with excellent maintenance, summer can bring about minor damage. Use infrared patching or saw-cut repair to deal with issues right away—especially if cracks are wide enough to allow water intrusion. The longer you wait, the more extensive and costly the damage becomes.
Summer Asphalt Maintenance Is an Investment in Longevity
You wouldn’t ignore maintenance for your roof or HVAC in peak season—your pavement should be no different. Proactively addressing heat’s impact ensures:
- Fewer liabilities from trip hazards and potholes
- Reduced repair costs long-term
- Consistent curb appeal for tenants and visitors
- Improved lifespan of your pavement investment
From heat-resistant asphalt upgrades to seasonal sealcoating programs, professional maintenance is essential to prevent both visible and hidden damage.
The summer season brings with it a unique set of challenges for asphalt surfaces. But with the right tools, knowledge, and support, your property can stay strong and look great—even through the hottest months. Don’t wait until cracks start forming or potholes develop—prevent them with a strategic plan focused on summer asphalt maintenance.
