Type 2 Slurry Seal - SNS Asphalt Services Cheaper A Type 2 Slurry is a much less expensive alternative to complete removal and replacement or an overlay. It is also a great solution for asphalt that is structurally sound but rough textured. Lifespan The lifespan of slurry seal is dependent on a variety of factors, but is typically 7-10 years.
This Handbook is focused on maintenance engineers and fitters and it is assumed that, in general, the selection of gasket type and material(s) will be decided by the plant operator or designer in the first instance. Hence, the maintenance operator may have little flexibility to choose the sealing material.
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.

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.".
Type II (general). 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. Type III (coarse).

The main types of seal coats are aggregate seals, fog seals, emulsion slurry seals, and sand seals. (10) Asphalt Surface TreatmentsApplications of asphaltic materials to any type of road or pavement surface, with or without a cover of mineral aggregate, which produce an increase in thickness of less...
Type II aggregates are the most commonly used and are widely employed where moderate-to-heavy traffic is found. They seal correct moderate-to-severe raveling, oxidation, and loss of matrix, and improve skid resistance. Type III corrects severe surface conditions — preventing hydroplaning and providing skid resistance under very heavy traffic loads.
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 Slurry seal is low cost with good performance at an expected service life of 4-7 years. Slurry Surfacing Slurry surfacing is laid at one-stone thickness.
