Slurry Seals

Slurry seal is cold mixed asphalt consisting of a mixture of an emulsified asphalt, mineral filler, fine aggregate, water and additives that is proportioned, mixed and uniformly spread over a properly prepared surface. It is used to seal aged and raveled pavement, fill minor cracks and restore skid resistance and restore aesthetic appeal. Slurry seals protect the existing pavement surface from the element of water, sun UV rays and traffic wear.

Slurry is mixed in a traveling paver truck as determined by a laboratory mix design and is placed by a specially designed spreader box. It is produced as three different types. Different stone sizes give different surface textures. Type I is fine and can be used for parking lots, runways and residential streets. Type II is coarser and general purpose it is used for all applications including arterial roads, residential areas and highways. Type III is the coarsest and is used on freeways and high speed roads and industrial estates. The price of slurry seal is approximately $16,500 per lane mile of roadway.
