A cape seal is a combination of a single-chip seal application followed by slurry seal or micro-surfacing. The slurry or micro-surfacing application helps fill the voids between the chips. The slurry bonds the chips to prevent loss, while the chips prevent undue traffic abrasion of the slurry. Cape seals are often used because of the aesthetics of the finished surface. Inverted cape seals are often used as a rut filled followed by a single-chip application for an economical solution to wheel path pavement deformation.
