Chip Seal Best Practices

About The Course

The National Center for Pavement Preservation (NCPP) Chip Seal Course is intended to provide participants with a thorough and comprehensive understanding of chip seal design, construction, equipment, and inspection. As a preventive maintenance treatment, chip seals offer superior pavement distress mitigation; retard the downward action of water, snow and ice; and provide improved skid resistance when applied to the right pavement. Because the primary causes of chip seal failure are poor construction practices and inappropriate roadway candidate selection, this course is designed to provide pavement practitioners with the essential skills needed to ensure success.

Target Audience

The course has been geared to a broadlybased audience, and is appropriate for anyone involved in the design, construction, or inspection of chip seals. Pavement practitioners who will benefit from the course include engineers, foreman, superintendents, designers, inspectors, and equipment operators. The material is well-suited for state and local transportation personnel, as well as consultants and contractors.

What’s Included?

The Chip Seal Course is designed to provide 1-day intensified training with an emphasis on practicality. Instructors are experienced chip seal practitioners with extensive backgrounds working with state and local transportation agencies. Participants will receive a notebook containing all course materials. The NCPP can provide arrangements for the class venue and/or meals during the day-long session on request for an additional cost.
