General Parameters & Advice

Slurry seal is designed for application on asphalt pavements that have adequate structural capacity. If an asphalt pavement is displaying structural distress, a different treatment should be selected. If an asphalt pavement is experiencing active rutting and/or shoving, it is not a candidate for slurry seal.

Site Selection for Specific Distresses

Although slurry seal is widely used in the preservation of good asphalt pavements, the treatment may also be used to address specific pavement distresses early on. This solves asphalt pavement problems early and avoids more invasive measures that may be required later on.

LOSS OF FRICTION, OXIDATION, RAVELING AND LACK OF UNIFORM COLOR: Asphalt pavement should be in good condition, free of potholes, alligator cracking, and other severe distresses. If localized distresses are present, they may be corrected with proper patching techniques before the slurry seal is applied.


Although slurry seal is typically placed on asphalt pavements, concrete and brick surfaces can be treated as well. This requires the application of a tack coat.

Road Type, Surface, and Traffic Specifics

Slurry seal can be used on a variety of asphalt pavement types, and throughout the range of traffic level: 

  • Highways
  • Collector streets
  • Residential streets and cul-de-sacs

To ensure success, the laboratory performing the mix design should be aware of your project’s application and use.
