Slurry Surfacing

Allan Henderson on the Advantages of Slurry Seal for asphalt paving and repair

Slurry seal forms a long-wearing, rock hard surface that provides years of use for both old and new roadways and parking lots. Slurry seal from American Asphalt is designed to extend the life of existing pavement by protecting the undersurface from the effects of oxidation, weather, and water seepage.

Slurry seal is an asphalt slurry mixture made from closely graded fine aggregate, emulsified asphalt and water, all carefully calibrated and mixed to form a mortar-like compound.This mixture is designed for easy and efficient spreading as a sealer on streets, playgrounds, parking lots and driveways. Slurry seal fills all voids, cracks and eroded areas. It furnishes a 3/16″ wearing course over the asphalt surface. This heavy coat serves as a proven sealer and an extremely durable, non-skid surface.

Slurry Seal Preparation

The asphalt area will be thoroughly cleaned using a power sweeper or power blower to remove all dirt and loose particles. All weeds and vegetation will be removed. Grinding, torching, scarifying or scraping with a shovel will remove accumulations of oil and grease in car stalls. These may adversely affect the slurry seal bonding. An application of poly-oil seal will be applied if necessary to any extreme areas, and then blotted with sand to ensure the best chance of bonding between slurry seal and heavily greased-soaked oil spots.

All drains, utility covers, monuments and manhole covers will be protected using duct tape and building paper.

Slurry Seal Application

Slurry seal will be applied with trucks mounted with continuous mixing machines. These trucks are large and not easily maneuvered in tight areas. Please make sure all vehicles are parked well off the work area. When applying slurry seal to small areas we use hand squeegees and other tools.

Drying time for Slurry Seal is estimated at 3-6 hours or longer depending on weather conditions. Please make sure everyone stays off the material until the barricades have been removed.
