Slurry Seal Treatment Types

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. This combined mixture of the emulsion and aggregates represents “slurry.”

Asphalt Seal-Coat Treatments

Asphalt emulsions with rejuvenating properties are being used as fog seals and sand seals to restore aged pavements and seal voids and cracks. The “scrub seal” method (figure 1) of using a pull broom following the asphalt-emulsion distributor truck and the sand spreader eliminates or reduces crack-sealing …

CHAPTER 8 SLURRY SEALS

The slurry mixture contains asphalt emulsion that breaks onto the pavement surface through heterogeneous or homogenous flocculation. The asphalt particles coalesce into films, creating a cohesive mixture. The mixture then cures, by loss of water, into a hardwearing, dense-graded asphalt/aggregate mixture that is bonded to the existing pavement.

High performance emulsion applications extend pavement ...

By Dwight Walker, P.E. Asphalt emulsions are widely associated with more routine applications like tack coats and seal treatments. While these uses of emulsions are important and successful, modern emulsions are also suited for more high performance pavement preservation applications.

Pavement Preservation Treatments - Intermountain Slurry Seal

Slurry Seal is a mixture of an approved emulsified asphalt, mineral aggregate, water, and additives. It’s proportioned, mixed, and uniformly spread over a prepared surface. Slurry Seal is designed to extend the life of asphalt pavements in good condition by providing skid resistance, restricting moisture intrusion, protecting against further oxidation, and restoring a uniform black appearance.

Slurry Surfacing - International Slurry Surfacing Association

Water is also added for workability. Asphalt emulsions serve as a binder, holding the crushed aggregate together and adhering the new slurry surfacing to the old surface over which it is being applied. Various emulsions and aggregates are used to meet the conditions, specifications, and requirements of individual projects.

What is slurry surfacing? Slurry surfacing is a thin dense-graded cold mixed overlay. Slurry seals are thin layers rich in asphalt used for residential streets, airports and in some countries for sidewalks and parking lots. Microsurfacing is a premium product based on specially selected aggregates and polymer modified asphalt emulsion.

Slurry Seal - roadresource

ASPHALT EMULSION: The asphalt used in slurry seal is emulsified before use and may be modified with a polymer. The emulsification process allows the asphalt to be pumped and mixed with aggregate at ambient temperature and allows the asphalt characteristics to be fine tuned to work in conjunction with the aggregate selected for the project.

Chip Seals | McAsphalt

A number of different types and grades of asphalt emulsions can be used in chip seals. The proper emulsion to be used is based on a number of factors; environmental conditions (temperature and humidity), traffic volume and type, type of cover aggregate and the existing road surface conditions (slope, shade, hills and curves).

Sand Seals | McAsphalt

A sand seal is a spray application of asphalt emulsion followed with a light covering of fine aggregate, such as a clean sand or screenings. Although this is a simple operation, it can be useful in correcting a number of pavement flaws. Emulsion is usually sprayed between 0.7 l/m 2 to 1.25 l/m 2 and sand is placed at 5.5 kg/m 2 to 12 kg/m 2 as ...
