SLURRY SEAL SURFACING. (REV 9-15-14) SECTION 335 SLURRY SEAL SURFACING 335-1 Description. Construct a slurry seal with the type of mixture specified in the Plans. Slurry seal is a mixture of polymer-modified emulsified asphalt, mineral aggregate, mineral filler, water, and other additives, properly proportioned, mixed and spread on a paved surface.

Seal Coats. The FAA specification also allows for prescribing a polymer additive as well. application rate for a 1:1 diluted emulsion is 0.10 to 0.15 The gallons per square yard (0.05 to 0.075 gal/sqyd undiluted). Similar to a fog seal application rate. For my driveway:

1. Type 1 (fine) This type has the finest aggregate gradation (smaller than 2.36 mm) and is used for filling small cracks. They are used as a preparatory pavement treatment and are limited to low traffic areas. 2. Type 2 (general) This type is coarser than the Type 1 slurry, and is the most commonly used slurry seal type.

There are three common sizes of slurry seal mixtures. The three mixtures are Type III (3/8-inch minus), Type II (1/4-inch minus), and Type I (1/8-inch minus). Generally, Type I slurry seals are used in parking lots and Type II and III seals are used on streets and higher traffic roads.

This type is coarser than a Type I aggregate slurry (it has a maximum aggregate size of 6.4 mm (0.25 inches)) and is used to (1) treat existing pavement that exhibits moderate to severe raveling due to aging or (2) to improve skid resistance. Type II aggregate slurry is the most common type.

Slurry seal is used to correct minor defects such as halts raveling, restores loss of matrix, and improves skid resistance. There are 3 types of slurry seal: Type 1 – Bike or walking trails, parking lots; Type 2 – Residential roadways; Type 3 – Highways, collectors, and arterial

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 ...

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. Micro-Surfacing is similar to slurry seal, except it hardens quicker.

PROJECT ID NO. SPECIAL PROVISIONS SECTION R - ROADWAY The following Special Provisions supplement and amend the Standard Specifications for Public Works Construction, 2015 Edition.

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.".

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.
