Crack Seal is the process of filling cracks and joints with asphalt materials, which keep water out of the pavement. When water is kept out, pavement deterioration is slowed. Crack Seal can be used on its own or in preparation for an additional preservation treatment, such as Chip Seal.
Benefits: Filling or sealing pavement cracks to prevent water from entering the base and sub-base can extend the pavement life by 3-5 years.
Challenges: Crack Seal application requires dry conditions and is restricted by precipitation. Therefore, inclement weather will delay application.
Because cracks do not typically form in straight lines, a Crack Sealed road may appear to have dark squiggly or “spider-like” lines running along it. Because of this, Crack Seal is typically not as aesthetically pleasing as other pavement preservation options.
What to Expect: Typically, Crack Sealing requires intermittent lane closures for the selected road, and work is completed same day.
