What is Crack Seal and how is it applied?
Crack Seal is a rubberized asphalt used to seal the cracks that frequently occur in an asphalt pavement. In order for the crack seal to adhere to the asphalt the crack must be clean and dry. The cracks are first cleaned out by applying compressed air to the crack. Then the crack seal is heated to 400 degrees Fahrenheit in a kettle and applied, while still hot, directly into the crack in the pavement.
Why Crack Seal is important?
- Prevents water from penetrating the asphalt and softening the pavement substructure.
- Prevents ice from freezing beneath the pavement causing heaving and eventual potholes.
- Acts as a binder and a bridge to prevent further breakage and cracking.
