What is a slurry coat?

A slurry seal is the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and additives to an existing asphalt pavement surface. A slurry seal is similar to a fog seal except the slurry seal has aggregates as part of the mixture.

How long does asphalt slurry last?

Longevity is affected by weather and amount of traffic. The industry recommends reapplying slurry seal every five to seven years and sealcoating every three to six years.

What is slurry in construction?

slurry, watery mixture or suspension of insoluble matter. In the manufacture of portland cement, a mixture of the raw materials with water is called a slurry. Cement may be piped as a slurry in building construction.

What is the most common uses of a slurry seal?

Slurry seal can be used on a wide variety of roads. Slurry seal’s most common application is asphalt 6-10 years old that have lost the fine aggregate in the original asphalt. People refer to this as “losing the fines” or “Boney asphalt” See picture below.

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 which allow it to break without relying on the sun or heat for evaporation to occur.

Is slurry seal smooth?

Slurry seal fills in the cracks and voids and creates a new wearing surface this creates a smooth surface after the slurry has been applied.

What is concrete slurry coat?

Slurry is a mixture of cement paste, pigment, and water. It is used to fill in the small air bubbles in the surface of the concrete. This is especially important in something like a concrete countertop, because bacteria can get into those holes and grow.

How do you make a slurry coat?

The ratio for a basic concrete slurry mix is 1 or 2 parts Portland cement to 1 part water. Start with equal parts cement and water, and then add more cement until you have the desired consistency.
