Extending Pavement Life through Pavement Preservation Techniques, Strategies, and Preventative Maintenance

Asphalt pavement

Date and Location

Not currently scheduled.

About the Workshop

This workshop provides an overview of the available technology and tools that make implementing a pavement preservation program feasible. An effective pavement preservation program encompasses a full range of maintenance strategies, as well as rehabilitation treatments, with the goal of enhancing pavement performance (ride, quality, safety, service life, etc.). Pavement preservation takes the maintenance process one step further by carefully choosing and timing pavement maintenance applications to extend the life of the pavement. Additionally, the workshop will introduce some new preventive maintenance technologies and allow time for specific discussions around attendees' needs.

Topics Covered

  • Techniques for asphalt pavement evaluation, including pavement condition rating
  • Discussion of how to select the best maintenance strategy; choose the right treatment at the right time on the right project and measures to track performance
  • Overview of various maintenance treatments and their construction practices: patching, crack seal/fill, fog seal, chip seal, double chip seal, slurry seal, microsurfacing, bonded thin overlay, thin overlay, new technologies and processes
  • Asset management concepts in raising your pavement network performance on a limited budget
  • Best practices in pavement preservation applications
  • Targeted pavement preservation topics specific to the interests of each class attendees

Who Should Attend

This workshop is designed for engineers, managers, supervisors, and technicians responsible for asphalt pavement maintenance, design, and construction.

Course Instructor

Dan Wegman, P.E., Braun Intertec, has worked with DOTs and local government agencies in several states with pavement rehabilitation and preventive maintenance strategies. As a former MnDOT construction and bituminous engineer, and with over a dozen years working as a private-sector material supplier, Wegman provides technical insight with respect to materials, construction, and implementation.
