Understanding the Appeal of Slurry Seal

When it comes to pavement treatments, slurry seal is one of the most popular and high-performance treatments. If you have cracked or uniformed pavement, you may want to consider the benefits of slurry seal.

What Is Slurry Seal?

Slurry seal is a homogeneous mixture. It includes well-graded fine aggregate, emulsified asphalt, and mineral filler. When applied to pavement surfaces, it has a fluid-like appearance. We use three basic aggregate gradations, which include:

  • Type I or fine
  • Type II or general
  • Type III or coarse

Each gradation has a specific use. Fine aggregate is used to fill small surface cracks by creating a thin level over the pavement. Sometimes, we can use a Type I aggregate slurry as a pre-treatment before an HMA overlay. On the other hand, general aggregate slurry can be used to treat moderate to severe raveling and improve skid resistance. Coarse aggregate slurry is for severe defects. We can use it to fill depressions to prevent ponding.

Why Would You Choose Slurry Seal?

At Asphalt Surfacing, we provide slurry seal and sealcoating. While sealcoating has benefits in low-traffic areas, slurry seal is great for roadways, airport tarmacs, shopping centers, and other high-traffic areas. Once it’s applied, you do have to wait about 8 to 10 hours for it to cure, but after that, it can last up to 10 years.

Slurry seal is considered a high-performance resurfacing treatment. It doesn’t just fill cracks, but it also adds a professional wear surface for additional protection. Slurry seal is a cost-effective solution to old, cracked pavement. With one application, you can have a uniform surface.

How Is Slurry Seal Applied?

To apply slurry seal, we use a spreader box connected to a slurry-mixing unit. The box spreads the slurry seal over the width of a traffic lane. The mixing procedure is automatic but constantly monitored by professionals. Personnel will clean the surface, barricade the area, and inspect your asphalt before application.

If you have cracked or depressed asphalt, our team at Asphalt Surfacing can assess the damage and decide whether slurry seal is right for you. To find out more about how we can help, call 408-673-4719 or send us an email today!
