Seal projects can be a chip seal, slurry seal, or cape seal.
A chip seal is the application of asphaltic emulsion, a type of road oil, immediately followed by an application of small rocks called chips. Chip seals are approximately 1/4 to 3/8 inch in depth over the existing road surface.
A slurry seal is the application of asphaltic emulsion and fine aggregate. Slurry seals are approximately 1/4 inch in depth over the existing road surface.
A cape seal is a chip seal covered by a slurry seal.
Seal-treated roads might undergo repairs to fix cracks and potholes. These repairs are performed before the seal and won't be visible after.
These types of seals are integral and cost-effective treatments utilized by the County to maintain roadways and extend their useful life.
