What is crack fill?
Crack fill is a relatively inexpensive first line of defense for an asphalt pavement against its biggest foe, moisture. Crack fill is a bituminous liquid blended with polypropylene fibers that is hot applied to cracks in the pavement larger than 1/8 inch wide. It is typically cooled with water immediately after placement so the road can be opened to traffic quickly. This material fills the crack and seals it, to help prevent water from reaching the aggregates and soil below the asphalt.

If you have any other questions about crack fill, please contact Construction Services.
