What is Slurry Seal?

Slurry seal is a highly adaptable and cost-effective pavement treatment system. You can use it for many needs, such as protecting newly laid pavement, fixing issues with old or deteriorating pavement, and improving pavement appearance.

Slurry treatment is a blend of asphalt emulsion, aggregate, filler, and water approved by the lab from which it originates. Asphalt emulsion acts as an adhesive that holds the aggregate together and sticks the slurry to the pavement.

Typically, slurry treatment is concocted with a wide range of aggregates and emulsions to meet the needs of specific projects.

Slurry treatments fall into three main types applied for different purposes. However, specialists can customize slurry treatments to meet your specific needs.

Ensuring the aggregate is adequately cleaned, crushed, and graded is essential to its effectiveness. The aggregate must also be robust and evened out to maintain long-lasting quality. High-quality slurry should have a lifespan of four to seven years.

It’s important to note that slurry is different from seal coating.

What is the Slurry Seal Process?

Operators use a spreader box connected to a mixing unit to apply slurry to pavements and roadways. Specialists put the slurry into the spreader box, and the spreader box sets the slurry onto the pavement as the mixing unit moves forward. A mixing unit can cover an entire traffic lane in a single pass, designed to stay in close contact with the preexisting surface.

Trained and certified specialists should always oversee slurry applications to maintain safety and quality. Specialists will operate the spreader and mixing unit, monitor the slurry as it mixes, inspect the project as they move along, and clean up equipment when complete.

Before application, specialists should block off the roadway and clean the pavement.

What Are the Different Types of Slurry Seal?

The type of slurry you need depends on the specifics and requirements of your project. Slurry treatments fall into three distinct types: fine, general, and course. Each type is defined by the grade quality of their aggregate, composed of different emulsions, and designed for specific purposes:

  • Type I (Fine): Fine aggregate covers cracks and minor damages. Type I is used for low-traffic or low-impact areas such as trails, parking lots, and driveways.
  • Type II (General): The most common type of aggregate. Type II is used for moderate traffic or moderate impact areas like residential roads.
  • Type III (Course): Type III is used to repair severe pavement and roadway damage, applied to heavy traffic and impact areas such as highways, freeways, and landing strips.

What is Micro-surfacing?

Micro-surfacing is similar to like slurry. However, the treatments have their differences.

Micro-surfacing consists of aggregate, emulsion, water, and mineral fillers like slurry. However, Micro-surfacing is deployed in thicker applications and is used for narrower courses such as wheel ruts.

Micro-surfacing can be applied to multi-layer surfaces and in double applications. Therefore, micro-surfacing is most effective for heavy-traffic areas such as highways, freeways, and airstrips.

How is Micro-surfacing different from Asphalt Slurry Seal?

A few key factors make micro-surfacing different from slurry treatments:


  • chemicals set faster, which allows for faster breaks.
  • Micro-surfacing can sustain traffic one hour after application.
  • Micro-surfacing needs advanced quality control for approval.
  • Micro-surfacing requires finer-quality aggregates to work.
  • Micro-surfacing has higher polymer content in the emulsion.
  • Micro-surfacing contains more asphalt residual content.
  • Micro-surfacing is strictly for type II (general) and type III (course).
