Types of Slurry Seal |
|||
|
Emulsion 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 II (coarse). Fine aggregate mixtures are used for maximum crack penetration and sealing in low density/low wear traffic areas. Type II aggregates are the most commonly used and are widely employed where moderate to heavy traffic is found. Type II seals the surface, corrects moderate to severe raveling, oxidation and loss of matrix, and improves skid resistance. Type II corrects more severe surface conditions and provides a course earing surface. Microsurfacing is a special kind of slurry seal that wears better and sets faster than standard slurry surfacing. This material uses special asphalt emulsion and is usually more expensive. A slurry seal for nearly any need or condition can be custom-designed to satisfy the most difficult requirements.
