What Is Asphalt Sealcoating?

What pavement is made of, why it fails, and what a sealer coat is supposed to do.

Outline

1. What You'll Learn

   A primer: pavement history and makeup, why it fails, what sealcoating does, and the basic rules for how often to come back.

2. A Brief History of Asphalt Pavement

   The article starts with asphalt as an old paving material, including an ancient Babylon road, before it explains modern hot mix. The history is context, not a field step.

3. What Asphalt Pavement Is

   Hot mix is graded rock held by asphalt cement, the heavy binder from oil refining. If the binder goes, the rock loosens.

4. How Asphalt Pavement Is Built

   Plant-mixed hot asphalt goes over a crushed-stone base on prepared soil. The article's point is that the surface you seal sits on that structure.

5. Why Asphalt Pavement Fails

   Weathering starts immediately. Sun, water, and chemicals attack the binder. Traffic speeds it up. Poor paving quality can fail the mat before maintenance ever starts.

6. What Sealcoating Does for Asphalt Pavement

   Sealcoating is the work. Sealer is the coating that bonds to the surface and shields binder from water, oil, sun, and chemicals. It is brushed, sprayed, or squeegeed.

7. Benefits of Asphalt Sealcoating

   The article groups benefits as protection of the binder, a darker appearance, and a cost well below replacement when the cycle is kept up.

8. Why Asphalt-Based Sealer Is the Future

   SealMaster's own case for asphalt-based sealer over coal tar: easier handling, low odor, flexibility, and a formulation it describes as lower in PAHs. Read that as the manufacturer's position.

9. How Asphalt Sealcoating Protects Pavement

   The film is a barrier. Applied to the maker's spec, the article also says it can restore a dark, slip-resistant surface.

10. How to Apply Asphalt Sealcoating

    The primer's application rules: at least two coats, with the first worked in by squeegee and the second sprayed for appearance. Temperature and prep limits are on the source page.

11. How Often to Sealcoat Pavement

    The article's cycle is every two to three years, timed before the binder is already gone. A schedule beats a one-time coat.

12. Learn More About How to Sealcoat

    The handoff is Sealcoat 101, which turns this primer into a cleaning, repair, and application sequence.
