Cape seal works best when the pavement does not have significant structural issues. If the road has many large potholes or major structural problems, an asphalt overlay is needed. Cape seal lasts as long as or longer than chip seal, as well as some asphalt overlays — extending the life of the pavement by up to 10 to 15 years.

2. Slurry seal cape seals exhibit a highly variable longterm performance even-though the conditions of the existing pavement at the time of application are mainly good as expressed by the high pre-PCI levels (85 to 100). This is shown by the wide range of the final PCI values of 62-92 (Figure 5). Comparison Based on Life Cycle Cost Analysis

A cape seal is used to both seal the road surface from moisture intrusion and improve ride. It is a two-step roadway surface treatment consisting of a chip seal covered by a slurry seal or micro-surfacing treatment. Chip seals are sometimes less desirable by the public because of the rougher pavement surface texture and ride is not improved.
Cape Seal Cape seal is a surface treatment consisting of a 9.5-, 13.2-, or 19-mm layer of stone placed shoulder to shoulder on a tack coat and covered with one or two applications of slurry so that the tops of the stones are left proud (26,27). Aggregate specifications for Cape seals are essentially those for single and slurry seals.
A cape seal is a process that includes placing a chip seal on the existing pavement surface. Then after a few days, a slurry seal or micro surfacing layer is placed on top of the chip seal. To place the chip seal, an asphalt distributor provides application of the binder to the pavement surface. A chip spreader immediately applies a uniform,

Washoe County's first use of cape seals was in 1999. The constructed cape seals consisted of a 9.5mm chip seal followed by a type 2 slurry seal. At the time, five roadways in the Truckee Meadow were treated with a cape seal placed over a fabric based on the experience of the City of Sand Diego, CA, USA. After observing field performance of
A Cape Seal is a chip seal covered with a slurry or micro-surface. The benefits from using a cape seal include a very smooth surface with an increased durability by sealing the subbase. Often the use of a chip seal is not popular with the public because of the rougher ride and loose stones.
