Road Treatment: Seal
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.
