Top 5 Asphalt Problems and How to Fix Them”* – Common issues like cracking and potholing, and how to properly address them.
Asphalt surfaces are common in roads, parking lots, and driveways due to their durability and cost-effectiveness. However, they are susceptible to various problems over time. Here are the top 5 asphalt problems and how to fix them:
1. Cracking
Types of Cracks:
- Alligator Cracking: Resembles the skin of an alligator, caused by a weakened base or sub-base.
- Linear Cracking: Long, straight cracks typically caused by temperature changes or poor construction.
Fix:
- Alligator Cracking: Requires full-depth reclamation. Remove the affected area, repair the base, and repave.
- Linear Cracking: Can often be repaired with crack sealing. Clean the crack, apply a crack sealant, and allow it to cure.
2. Potholes
Cause:
- Water infiltration, freeze-thaw cycles, and traffic wear lead to the breakdown of the asphalt.
Fix:
- Clean the pothole of debris and loose material.
- Apply a tack coat to the sides and bottom.
- Fill with hot or cold asphalt mix.
- Compact the mix and ensure it’s level with the surrounding pavement.
3. Raveling
Cause:
- The loss of aggregate from the asphalt surface, often due to poor compaction or aging.
Fix:
- For minor raveling, apply a seal coat to bind the surface.
- For severe raveling, remove the top layer and repave.
4. Depressions
Cause:
- Poor compaction during installation or settling of the underlying soil.
Fix:
- For minor depressions, apply a leveling course of asphalt.
- For significant depressions, remove the affected area, address any issues with the sub-base, and repave.
5. Water Pooling (Bird Baths)
Cause:
- Poor drainage or an uneven surface leading to water accumulation.
Fix:
- Ensure proper drainage design during installation.
- For existing bird baths, mill the affected area to create a slope for drainage and repave with a thin overlay.
Preventative Measures
To minimize these issues, regular maintenance is crucial:
- Seal Coating: Apply every 2-3 years to protect the surface.
- Crack Sealing: Address cracks as soon as they appear to prevent water infiltration.
- Proper Drainage: Ensure good drainage design and maintenance to prevent water damage.
