The Case for Cape Seal Resurfacing

This article describes in detail the use of cape seal, which is a combination of chip seal and slurry seal, and presents it as an economical and better alternative for residential and connector roads requiring a smooth yet durable finish. The finished product is similar to an asphalt overlay, but less expensive to install. The author describes the process of applying cape seal, offering a summarized six step process which involves: road preparation, emulsion (spraying oil on the pavement), aggregate dispersion, rolling the aggregate into oil, removing extra aggregate, and applying a layer of slurry seal. While cape seal originated in South Africa in the 1950s, its use in the U.S. has been limited. Although there are many conditions that can affect the efficiency of cape seal, it has its advantages, such as particular durability against snowplow blades on high-volume roads.
