Slurry Seal Slurry Seal is a mixture of well-graded aggregate, slow-setting asphalt emulsion, fines, and additives. It can seal sound, oxidized pavements, restore surface texture by providing a skid-resistant wearing surface, improve waterproofing characteristics, correct raveling, and provide a new surface where weight restrictions preclude the

The completed slurry seal mixture after addition of water and any control agent used, shall be such that the slurry seal mixture has proper workability and (a) break,

Slurry seal is a specifically-designed mixtures of asphalt emulsion, aggregate, water, mineral filler and additives, mixed in set proportions, and uniformly spread across a prepared surface. Benefits of Slurry Sealing

Type I slurry contains 1/8" aggregate and is commonly used for maximum crack penetration and sealing in low density/low wear traffic areas. 2 Type II slurry uses 1/4" aggregate and is commonly used to seal, correct moderate to severe raveling, oxidation …

Slurry Seal is a cold mixture of fine graded aggregate, asphalt emulsion, mineral fillers, polymer and water applied to a pavement as a surface treatment. Slurry seal is used as both a preventive and corrective maintenance of asphalt pavement but is not intended to increase the structural strength of a pavement section.

What exactly is slurry seal? Each slurry seal mixture is unique, with a composition similar to fog seal. Depending on the ingredients, we use it to impart a rich black color and texture, repair pavement defects such as cracks and voids, improve skid resistance, and …

Slurry seal. Slurry seals are a preventive maintenance surface treatment of emulsified asphalt, dense graded aggregate, additives, and water that seals the asphalt pavement and improves the texture of the road surface. Slurry seals may be polymer modified to enhance performance, improve adhesion, and extend application life span.

8.1.2 Purpose of a Slurry Seal A slurry seal is a thin surface treatment that is laid in a thickness equal to the largest stone in the grading of its component aggregate. It may include either a conventional or polymer modified emulsion, and the slurry seal may be slow or quick setting. The emulsion is usually cationic in nature, but may be ...

The slurry seal application provides a new wear surface due to its aggregate combination, unlike a seal coat, which provides a smoother surface sealer that protects asphalt from oxidation and moisture penetration. Slurry seal is a popular choice for clients needing resurfacing services thanks to its durability and attractiveness.

Chip Seal is an application of a bituminous binder covered with an application of clean graded aggregate to an existing asphalt surface. It is also known as bituminous surface treatment or seal coat. The binders may be emulsified asphalts, paving grade asphalt cements, and versions of each being modified with various polymers.

Section 427—Emulsified Asphalt Slurry Seal 427.1 General Description This work includes placing slurry seal. Emulsified asphalt slurry seal is a thin application of a mixture of fine non-plastic aggregate, emulsified asphalt, mineral filler, and water. 427.1.01 Definitions General Provisions 101 through 150. 427.1.02 Related References

A slurry seal is a mixture of quick setting asphalt emulsion, fine aggregate, mineral filler, additive, and water. The ingredients are carefully measured and combined on the project site and spread with a squeegee device.

Slurry Seals. Slurry seal is a homogeneous mixture of bitumen emulsion, water, well-graded aggregates and mineral filler, mixed as per a design formula, and applied to an existing asphalt pavement surface. Slurry seals are laid on the existing pavement, to seal cracks and voids, thereby making the surface weather tight and providing a new look.

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.".

The work shall consist of mixing asphaltic emulsion, aggregate, additive, and water and spreading the mixture on the pavement where shown on the Plans. Type I and Type II slurry shall be applied at the application rate shown in Table 302-4.3.1 (A). TABLE 302-4.3.1 (A) Slurry Seal Min. Max. Min. Max.

Slurry Seal vs. Sealcoat. The aggregate particles found in all types of slurry seals tend to improve overall adhesion and integration with the existing pavement. As a result, slurry seals tend to last longer than sealcoats. Whereas contractors recommend sealcoating asphalt roughly every two years, slurry seals only need to be applied every five ...

Slurry seal is a cold mix coating consisting of fine crushed aggregate, emulsified asphalt, additives, and water applied to roadways. Emulsion serves as a binder to hold the aggregate together and to adhere to the roadway. Slurry seal is very economical and extends the life of pavement up to 7 years.

Slurry seal is a mixture of aggregate, asphalt emulsion, and filler, which are mixed together according to a laboratory's design-mix formula. 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.

The main difference is that slurry seal has large aggregate. In most cases asphalt sealer will dry in a few hours,but we recommend to stay off of it for 12 hours to ensure that it is fully cured out. In extremely hot climates it may take upwards of 72 hours to allow the sealcoat to fully dry enough to park on.

The slurry seal must build sufficient cohesion to resist abrasion due to traffic. Otherwise, it will ravel off quickly, particularly in high stress areas Early stone shedding is normal, but should not exceed 3% General rule of thumb for a slurry seal . Chapter 8 –Slurry Seals

The aggregate for slurry seal shall be Type II. Aggregate shall consist of sound, durable, crushed stone or crushed gravel. The material shall be free from vegetable matter and other deleterious substances. If aggregates are blended each component aggregate shall meet the sand equivalency and abrasion

aggregate varies from 1/4 inch to 3/8 inch, depending on the application. Aggregates, which are entirely manufactured, seem to give a better end product and a more durable slurry seal. The aggregate is mixed with a CSS-1, CSS-1h or Cationic Quick Set (CQS-1h) asphalt emulsion. The percent of emulsion is determined

Section 520 - Slurry Seal 520.1 Slurry seal and all work shall be performed and conform to the provisions in Section 37-2, "Slurry Seal", of the Caltrans Standard Specifications and these Special Provisions. Aggregate shall be Type II spread at a rate of 14 pounds of dry aggregate per square yard.

Recommended application rates are 9.8- 16.3 kg/m² For further information on how to make slurry seal part of your preventative maintenance program, or which type best suit your needs, contact us today, and protect your paving investments.

A cost-effective method of restoring the surface finish with texture and sealing which will slow down deterioration and thereby extend the service life of the surface. A quick and easy solution for many road and footway maintenance problems. Rhino slurry uses a blend of aggregate, bitumen emulsions and latex to provide a slurry seal for:
