Sealcoat Prep and Application

Asphalt Sealcoat Application: Key Considerations and Procedures

 

The decision to apply sealcoat to asphalt pavement involves multiple factors that determine both suitability and application methods. This section covers the complete process from evaluation to application:

  1. PAH Testing and Historical Assessment​

  2. Asphalt Condition Evaluation​

  3. Material Handling and Safety​​

  4. Surface Preparation​

  5. Application Techniques​

 

Each of these factors contributes to successful pavement preservation. Proper evaluation and preparation are equally as important as the application itself to ensure long-lasting results.

1. ​PAH Testing and Historical Assessment

  • Methods to test for previous high-PAH sealant applications

  • Laboratory analysis techniques for asphalt samples

  • Field testing options for preliminary assessment

5. Application Techniques

  • Brush application: Best for small areas and detailed work

  • Squeegee method: Provides uniform coverage

  • Spray application: Most efficient for large surfaces

  • Environmental conditions for optimal application

  • Quality control during application
