Chip seals are a common type of surface seal. They provide one of the best forms of sealing the surface against moisture intrusion, can significantly increase the surface friction, and can extend the service life of an asphalt pavement as a preservation treatment. Although chip seals typically provide good performance, there are occasions when a chip seal fails prematurely or does not provide the expected service life. This training describes how to achieve maximum performance and avoid premature failure.

After the training, you will be able to:

  • Compare the types of chip seals based on their strengths and weaknesses.
  • Use standard guidance and pavement condition information to select a good chip seal candidate.
  • Identify design and construction practices that ensure performance.

Attendees for this class include people who select, design, construct, or inspect chip seal projects.
