This workshop is designed to provide 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.

Course Instructors

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.

Tom Wood, Pavement Specialist, WSB & Associates Inc., has worked in road construction/maintenance for over 40 years. He has a blend of public and private service experience. For the last 18 years, he has worked on pavement preservation treatments specializing in emulsion base methods. He also teaches classes for numerous LTAPs and the National Center for Pavement Preservation. Wood retired from MnDOT early in July 2016 after more than 28 years of service. He currently works for WSB & Associates, continuing to promote the use of pavement preservation as method to extend pavement’s useful life.
