Asphalt is a strong and durable paving material, but intense summer heat can take a toll on its structure. When temperatures rise, asphalt surfaces become softer, more prone to cracking, and susceptible to long-term damage.

If left unchecked, these issues can lead to hazardous conditions, costly repairs, and reduced pavement lifespan. In this guide, we’ll break down how summer heat affects asphalt and why hiring a professional asphalt repair company is your best solution.

☀️ How Los Angeles Heat Damages Asphalt

1. Asphalt Softens Under Extreme Temperatures

Asphalt contains bitumen, a petroleum-based binder that holds the pavement together. When exposed to high temperatures, bitumen softens, making the asphalt more:
✔ Susceptible to indentations from heavy vehicles
✔ Prone to rutting (permanent wheel track depressions)
✔ Vulnerable to deformation and uneven surfaces

If asphalt is frequently exposed to temperatures above 100°F, it can begin to degrade more rapidly.

2. Expansion & Contraction Cause Cracks

Asphalt expands when heated and contracts as it cools down at night. Over time, this constant expansion and contraction cycle weakens the pavement, leading to:
✔ Surface cracks
✔ Splitting at the edges
✔ Weakened foundation layers

Once cracks appear, water infiltration becomes a major issue, worsening the damage and increasing the risk of potholes.

3. Oxidation Causes Fading & Brittleness

The sun’s UV rays accelerate the oxidation process in asphalt, causing it to:
✔ Fade from deep black to gray
✔ Become brittle & lose flexibility
✔ Develop surface cracks

Oxidation not only affects aesthetics but also reduces structural integrity, making the asphalt more prone to deterioration.

4. Increased Oil & Gas Stains Weaken Asphalt

During summer, high temperatures cause vehicles to leak more oil and gasoline. These substances break down the asphalt binder, creating soft spots that quickly turn into potholes or sinkholes.

🏗️ Why Professional Asphalt Repair is the Best Solution

Instead of waiting for small issues to become major problems, hiring an asphalt repair company ensures:

1. Timely Crack Filling to Prevent Potholes

✔ Professional contractors use rubberized crack sealants that expand and contract with the pavement.
✔ Prevents water infiltration that leads to potholes and base layer erosion.

2. Sealcoating for UV & Heat Protection

✔ Sealcoating acts as a protective barrier against oxidation, fading, and water penetration.
✔ Helps asphalt retain its deep black color, improving curb appeal.
✔ Reduces softening and rutting by keeping bitumen intact.

3. Resurfacing & Overlays for Extreme Damage

✔ If asphalt is severely damaged, professionals can remove the top layer and apply a fresh one.
✔ Overlaying improves strength without needing a full replacement.

4. Proper Drainage Solutions to Prevent Heat-Induced Expansion Damage

✔ Ensures that water runoff doesn’t cause cracks to expand.
✔ Stops erosion and soft spots under the pavement.

🚧 Summer Asphalt Maintenance Tips

✅ How to Protect Your Asphalt from Sun Damage

• Sealcoat every 2-3 years to prevent heat and UV damage.

• Fill small cracks immediately before they turn into potholes.

• Avoid parking heavy vehicles in the same spot to prevent depressions.

• Keep asphalt clean from oil, gas, and chemical spills.

• Schedule routine inspections with a professional paving company.
