Slurry seal is a mixture of aggregate, emulsified asphalt, water and additives that are properly proportioned, mixed and spread over a prepared surface. A polymer-modified system can be used in the same application and will enhance one or more properties of the slurry to better meet a particular project requirement.
Making the seal components and pump elements harder than the solids in the slurry is a critical design consideration. A variety of flush plans can be applied so that the seal faces are not being affected by 100 percent of the abrasive slurry. Process-compatible barrier fluids can be used to minimize dilution of process liquids.
Slurry seal is a mixture of well-graded fine aggregate with mineral filler and dilute asphalt emulsion. A single course is usually applied in thicknesses of 3–6 mm (1/8–1/4 in.). Slurry seals are effective in areas of excessive oxidation and hardening of the existing asphalt and are used for sealing minor surface cracks and voids, retarding ...
The aggregate found in slurry seal helps to fill in those small cracks and gaps and promote a more even asphalt surface while improving overall adhesion and integration with the existing pavement. As a result, slurry seals typically outlast seal coating. Whereas contractors recommend applying seal coat to asphalt every two years, …
Slurry Seal is a protective sealant coat which extends the life of pavement. It is a thin, tough layer of asphalt emulsion blended with finely crushed stone for traction. The name may sound a little odd – a close rhyme with "Furry Seal" – but we guarantee this road maintenance method has nothing to do with the cute sea creatures.
Slurry Seal. A slurry seal ought to be applied at 25% of the design life for maximum benefit in preserving the pavement structure. Maintenance with a slurry seal must be instituted before significant pavement deterioration occurs. Aggregate size, emulsion type, and any additives determine classification of the slurry seal. ...

Milwaukie Engineering has committed to slurry seal nearly 860,000 square feet of roadway during the summer of 2023. A slurry seal is a cost-effective method of reconditioning and extending the life of asphalt roadway surfaces. The treatment will improve the overall condition of Milwaukie's public roads. Engineering keeps track of the …
Slurry seals address longitudinal cracking, transverse cracking, weathering, the loss of friction, moisture infiltration, and roughness. Slurry seals are especially effective at improving friction on roads with vehicle speeds below 30 mph, and for water-proofing the pavement surface.

Slurry seals are highly resilient and better suited to filling worn and unraveled areas, because of the aggregate mixed in, and they last longer — up to 10 years, versus five for seal coats. However, the heavy …
The equipment division of the Valley Slurry Seal, Co. family, VSS Macropaver, stemmed from the need within the construction industry for a faster, more durable piece of machinery that was capable of …
A wood pulp slurry in a paper pulping application is a perfect example of such a condition. The slurry will collect at low laminar flow areas closest to the seal gland and dewater. This dewatering insulates the seal faces from the fluid in the seal chamber, thus supporting a dry run condition and generating excess heat.
Slurry Seal Checklist 2 Project Review Verify that the project is a good candidate for slurry seal by confirming the absence of any alligator cracking indicative of subgrade failure or inadequate subsurface drainage. Investigate whether any rutting exists on the pavement, and if so, is ¼ in. or less in depth.
As the most versatile of any pavement surface treatment system, slurry seal is also a unique bituminous mixture that can be used to meet the demands of a variably textured surface filling cracks and voids, sealing the surface weather-tight, and providing color and texture delineation in a single pass.
When: Slurry seals are recommended when the primary deterioration is related to oxidation and hardening of the existing asphalt. Slurry seals are most effective on pavements with only very minor cracking (less than 1/8") or raveling. Estimated life extension: 6-7 years over pavements in good condition; 3-6 years on pavements in fair condition ...
Slurry Seals. In the harsh and difficult environment of slurry applications, John Crane's range of rugged slurry seals are designed to resist the destructive effects of ore, …

Hard slurry particles enter the seal faces (primary seal) because of either their submicron size or undesirable pumping system hydraulics such as cavitation, nonhomogeneity, or solids aggregation. A carbon-graphite face is prone to scoring because the material is much softer than the slurry particles.
