A cape seal is effectively a combination of two separate treatments, a chip seal and a slurry seal. The chip seal is placed first, followed within a few days or weeks by the slurry seal. This enhances the binding of the chips with the asphalt and prevents loose aggregate from being dislodged. Cape seals provide a new wearing surface and can address more significant deterioration than either of the treatments individually. They can be an effective treatment for pavements where some distress is present, but a more expensive overlay is not required.
