Hot Mix Patching During Pittsburgh Winters?

When it comes to repairing roads, parking lots, or driveways, the choice of asphalt mix can significantly impact the outcome of the repair. While both hot mix asphalt (HMA) and cold mix asphalt (CMA) have their place in asphalt maintenance, HMA offers several compelling advantages for patching work. Don't worry, here at Collins Paving, we can provide hot mix asphalt ALL WINTER LONG!

1. Enhanced Durability

Longevity: HMA is mixed and laid at high temperatures, which ensures a thorough blend of asphalt binder and aggregate. This results in a more durable patch that can withstand the rigors of traffic and weather for a longer period than CMA.

Resistance to Wear: The strong bond created by the heated process means that HMA patches are less likely to unravel under heavy traffic or extreme temperature changes.

2. Superior Performance in High-Traffic Areas

Traffic Tolerance: HMA patches perform exceptionally well in high-traffic areas due to their stability and resistance to deformation. This is crucial for busy roads or commercial parking lots where the surface is under constant stress.

Reduced Rutting: The higher quality of HMA means less likelihood of rutting or pothole reformation, ensuring a smoother ride and safer road conditions.

3. Better Bonding and Adhesion

Adhesion: HMA's heated application allows it to bond more effectively with the existing pavement. This strong adhesion prevents water infiltration, which is a common cause of further deterioration.

4. Environmental and Economic Considerations

Recyclability: Modern HMA production can recycle old asphalt, reducing waste and the demand for new materials, which is environmentally beneficial.

5. Improved Ride Quality

Smooth Surface: HMA patches typically result in a smoother driving surface, which can enhance vehicle comfort, reduce noise, and decrease wear on vehicles.

6. Optimal Weather Conditions

Weather Versatility: While HMA is generally applied in warmer conditions, when managed correctly, it can still provide superior patching compared to CMA, even in less ideal weather scenarios.

Why Cold Mix Still Has Its Place

It's important to note that CMA does have its advantages, particularly for emergency repairs, smaller projects, or in colder climates where HMA isn't feasible due to temperature constraints. However, for long-term, quality patching, HMA stands out.

Conclusion

When planning to patch roads or parking lots, especially in areas with significant traffic or where you want longevity, Hot Mix Asphalt should be your go-to choice. Its durability, performance under stress, and superior bonding capabilities make it the superior option for anyone looking to invest in a patch that will last.
