Repairing Cracks in Asphalt Surfaces

Water is dangerous when combined with cracks in an asphalt surface. It can easily penetrate the surface of asphalt pavement through unsealed cracks. Water infiltration of exposed cracks will weaken the structure and lead to structural failure of the paved surface and the base it is built upon. Water trapped inside asphalt will eventually cause the foundation to erode. Pavement cracks left unfilled allow excess moisture to assault the inner layers of the asphalt and cause premature failure and pothole development. Once this damage is done, asphalt surfaces require costly, extensive repairs to become viable again. As soon as you notice any asphalt cracks, crack filling will help protect your asphalt surfaces from structural failure.

What causes asphalt cracks?

Though California rarely experiences temperatures below freezing, in many other parts of the country, asphalt cracks left unrepaired through the cold winter months can grow quickly due to freezing and thawing cycles that continually weaken the already damaged surfaces. Likewise, in parts of the country that experience little in the way of freezing temps, the exposure to excess sunshine, humidity, and oxidation can cause similar damages to asphalt surfaces.
Many common things can cause cracks in asphalt surfaces, including:

  • Extreme temperature changes, lack of traffic, excessive UV exposure, and water infiltration can cause shrinkage and surface cracks.
  • Temperature and moisture fluctuations can cause horizontal or vertical movement beneath the pavement causing reflective and structural cracks.
  • During installation, improper pinch rolls and weak seams during installation cause seam and joint cracks to develop.

How are cracks repaired?

Patching small cracks or potholes only acts as a temporary fix to the damages incurred and often does not last very long. Choosing to crack seal damaged pavement as quickly as possible once the damage is discovered can help extend the life of an asphalt surface. Early intervention is likely to halt the need for premature and costly replacement of your pavement. Crack filling can stop the accumulation of dirt and debris and the growth of plants and weeds in cracked pavement. Preventative maintenance is vital at first sight of damage to protect and extend the life of asphalt surfaces. It will also save you money for replacement in the long run.

A contractor specializing in asphalt paving in Lockeford, CA, will repair any cracks in your paved surfaces through the following process:

  1. Cleaning out the cracks. Asphalt companies use crack cleaning machines, screwdrivers, or steel brushes to remove vegetation and dirt down to at least half an inch deep.
  2. Filling small cracks. For cracks more minor than half an inch, the asphalt contractor will use a product to fill in the voids. However, this product does not work well for larger cracks because it is not designed to fill more significant areas appropriately.
  3. Filling larger cracks. Crack filler is then melted into its liquid form and poured into larger cracks to ensure tight and proper filling into larger asphalt voids.

When left unattended for too long, unsightly asphalt cracks will grow in size and become more expensive to repair. The risk of rapid growth makes it vital to inspect asphalt surfaces consistently. The faster you notice cracks, the sooner you can have them repaired. Repairing minor asphalt damages through crack filling or sealing is the most economical and reliable way to stop the erosion of your asphalt surfaces. When properly applied to damaged asphalt by a paving professional, crack sealing materials can prevent further damage and extend the life of your paved surfaces.
