Slurry Seal

Quick-set slurry is emulsified asphalt, crushed rock and cement mixed and applied with specialized equipment forming a thick, tough, durable mixture that:

• Fills cracks
• Seals against damaging moisture invasion
• Completely hides utility trench patches and other repair work
• Resurfaces your asphalt with a 1/4 to 1/2″ attractive,
  skid-resistant finish
• Lasts from three to five years depending on weather conditions

Asphalt emulsions serve as a binder, holding the crushed aggregate together and adhering the new slurry seal to the old surface over which it is being applied. Various emulsions and aggregates are used to meet the conditions, specifications, and requirements of individual projects.

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. 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, loss of matrix, and improve skid resistance. Type III corrects severe surface conditions – preventing hydroplaning and providing skid resistance under very heavy traffic loads. 

The aggregate must be clean, crushed, durable, properly graded, and uniform. The asphalt emulsion is a three-part system consisting of asphalt, water, and emulsifier. Fillers such as Portland cement, hydrated lime or aluminum sulfate liquid are often used in small quantities as stabilizers or chemical modifiers.

Slurry seal is today’s choice in providing highly durable, low-cost  paving, and surface maintenance. As a treatment for everything from residential driveways to public roads, highways, airport runways, parking lots, and a multitude of other paved surfaces, slurry seal is now used extensively throughout the world. Local, state and federal agencies have a growing and ongoing commitment to the use of slurry seal in their maintenance programs, attesting to its effectiveness and economy.

A slurry seal for nearly any need or condition can be custom designed to satisfy the most difficult requirements.
