Crack Filling, Line Striping, & Seal Coating: Why are they so important?

Crack Filling, Line Striping, & Seal Coating are important parts of pavement protection. Asphalt will deteriorate over time, causing it to be in need of repairs. In fact, pavement starts to wear down as soon as it is laid. After a year, the dark black color will begin to lighten and the pavement will start to lose its plasticity, causing minor cracks to form. After 5 years of non-maintenance, the asphalt becomes brittle. Crack Filling, Line Striping, & Seal Coating will increase the life of the asphalt.

Crack Filling is a part of pavement protection.
  • Tree Roots
  • Installation of drains & sewers
  • Utility Cuts (installation of fiber optics)
  • Extreme Differences in temperature
  • Heavy construction vehicles driving on the surface
  • Fuel & Lubricants
  • Improper Design

Extreme differences in temperature is the most common cause of crack filling. Water seeps underneath the pavement. During the winter, water will freeze and then expand, causing cracks to form. Cracks that are left unfilled, allow even more rain and moisture to seep through. Therefore the pavement erodes and potholes form. Filling cracks on a regular basis will help prevent those problems. It is important to note that sealing is not a crack filling agent. Crack filling should be done prior to seal coating. Also, it is not a final solution. It is merely a temporary solution and will help extend the life of the pavement and prevent major repairs. Out of all three services: Crack Filling, Line Striping, & Seal Coating, crack filling is usually the first step in the process.

Line Striping

Seal coating is recommended for pavement that is aging and losing its color. Seal Coating has the following benefits:

  • Fills small, hairline cracks
  • Replenishes asphalt binder
  • Protects against fuels and leaks (acts as a barrier)

The above benefits will in turn reduce maintenance costs, optimize safety, and allow the asphalt to remain structurally sound. Prior to seal coating, the surface must be completely clean. After the process is couple, and both coats of sealant are applied, vehicles must remain off the asphalt in order for the sealant to harden.

Seal coating should be done every three years. This will help maintain the pavement and will more than double the life of the asphalt.
