A graded aggregate seal is a seal coating that uses a well-graded aggregate rolled into a high-float, emulsified asphalt, also known as a dense-graded seal. A typical gradation is 98% less than 16 mm, with 2%–7% passing the 75 mm sieve. Aggregate gradation determines the application rate of the emulsion.
A summary of the quantity and application rate of slurry seal placed and a list of the quantities used for each of the slurry seal components (i.e., aggregate, emulsified asphalt, mineral filler, and additive) shall be submitted daily to the Contract Administrator.
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. ...
slurry seal. The material shall be mixed by a self-propelled slurry seal mixing machine of either truck mounted or continuous run design. Either type machine shall be able to accurately deliver and proportion the aggregate, emulsified asphalt, mineral filler, and water to a revolving mixer and discharge the mixed product on a continuous flow basis.
Types of Slurry. Emulsions of varying composition and setting times are mixed with any one of three grades of aggregates to create slurry seal mixes for specific purposes. Aggregate types are I (fine), II (general), and III (coarse). Fine aggregate mixtures are used for maximum crack penetration and sealing in low-density/low-wear traffic areas.
Limitation: This seal has the same limitations as a fog seal except that a sand seal i I may not provide the distinct delineation that a fog seal does, depending on aggregate I I I color, Slurry Seal A slurry seal is a mixture of well-graded, fine (sand size) aggregate, mineral filler (in most cases), and dilute asphalt emulsion.
3.1 This method can indicate the impact of aggregate fines on slurry system performance. 4. Summary of Method 4.1 Methylene blue solution is titrated into distilled water containing aggregate fines passing the 75 μm (No. 200) sieve. A drop of aggregate fines/methylene blue so lution is removed via a glass rod and placed on to filter paper.
slurry surfacing and the pavement characteristics they improve are discussed next. 9.1.2 Types of Slurry Surfacing There are two main types of slurry surfacing in common use. These include: • Slurry Seal • Microsurfacing Currently, Caltrans uses slurry seals routinely, while microsurfacing is still in the pilot stages of assessment.
Wilson Type III Slurry Seal Aggregate. This crushed granite product is used specifically for Cal Trans slurry seal projects, and meets Cal Trans Section 37-8 for slurry aggregates. This aggregate is typically gray in color. Asphalt Calculator Asphalt Calculator.

Slurry Seal Vs Seal Coat. Slurry seal vs seal coat—which of these sealing options is right for your road paving, asphalt driveways, parking lots or playgrounds?While the terms are often used interchangeably because both protect and extend the life of your asphalt surfaces, the two applications are different.
A preventive or corrective maintenance surface treatment composed of a mixture of dense-graded aggregate, emulsified asphalt, mineral fillers, additives and water. The slurry seal improves surface texture, and seals and protects the pavement. Emulsion is mixed with aggregate and then placed on road. Can fill some cracks.

A slurry seal is a homogenous mixture of emulsified asphalt, water, well-graded fine aggregate and mineral filler that has a creamy fluid-like appearance when applied. Slurry seals are used to fill existing pavement surface defects as either a preparatory treatment for other maintenance treatments or as a wearing course.There are three basic aggregate gradations used in slurry seals:
The appropriate binder type is selected based on pavement condition, climate, aggregate properties, desired service life and cost considerations. A chip seal is designed to seal and protect a pavement from oxidation and weathering by sealing the small cracks in a .
