Question: What Is A Cape Seal?

A cape seal is an application of a chip or scrub seal followed by the application of slurry seal or microsurfacing at a later date. Why? The chip or scrub seal serves to seal and bond the cracks in the existing pavement.

How long does Cape seal last?

Conventional Emulsion Chip and Cape Seals last about 6 to 8 years on roads with 1/8” to 1/4″ alligator cracks. Asphalt-Rubber Chip and Cape Seals last about 12 to 15 years on roads with 3/8” to 1/2″ alligator cracks.

What is Cape seal in road construction?

A cape seal is a roadway surface treatment designed to extend the life of pavements in fair to good condition, consisting of a chip seal treatment, which is then covered by a slurry seal or micro surfacing treatment.

What is a scrub seal?

Scrub Seals A scrub seal is an application that is very close to a chip seal treatment where asphalt emulsion and crushed rock are placed on an asphalt pavement surface. These brooms guide the asphalt emulsion into the pavement distresses to ensure sealing the road.

Can you chip and seal over concrete?

Chip seal can be completed over existing gravel surfaces, unsealed asphalt, concrete, or previously chip sealed surfaces.

Is tar and chip cheaper than asphalt?

A tar-and-chip driveway will typically cost about twice as much as a gravel driveway and a little less than an asphalt driveway. While gravel makes for a cheaper driveway surface, tar-and-chip creates a harder, more durable surface, though it is considerably less durable than concrete.

What is Microsurfacing of a road?

Microsurfacing is similar to slurry seal. It consists of the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and chemical additives to an existing asphalt concrete pavement surface. Polymer is commonly added to the asphalt emulsion to provide better mixture properties.

What is the difference between micro surfacing and slurry seal?

The major difference between slurry seal and microsurfacing is in how they “break” or harden. Slurry relies on evaporation of the water in the asphalt emulsion. The asphalt emulsion used in microsurfacing contains chemical additives that allow it to break without relying on the sun or heat for evaporation to occur.

Can you tarmac on top of concrete?

It is safe to pave asphalt over concrete. Concrete is a great base material because it is stable and allows for excellent compaction of the asphalt above. In fact, many miles of concrete roads are paved over with asphalt every year.

Is Tar cheaper than paving?

5. Tar-and-Chip. Akin to the asphalt option, but cheaper and a little less attractive, is the tar-and-chip solution to your paving requirements.

What are the pros and cons of sealing a concrete driveway?

Seal Driveway or Not?: Pros and Cons of Concrete Sealing

  • A sealer, such as an epoxy flooring can help repel moisture and keep it on the surface.
  • A sealer is stain-resistant.
  • Sealed floors last longer.
  • Sealers enhance and maintain appearance.
