Flex Preservation and Rehabilitation

Description: 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 preventative maintenance technologies. Topics include: Techniques for asphalt pavement evaluation, including pavement condition rating and non-destructive testing; Discussion of how to select the best maintenance strategy; choose the right treatment at the right time on the right project; Overview of the various maintenance treatments and their construction practices: fog seal, chip seal, double chip seal, slurry seal, micro-surfacing, Macro®–Surfacing, bonded thin overlay, thin overlay, new technology or processes; Overview of material properties—how they are produced, and proper handling and storage of aggregates, emulsions, cutbacks, and asphalts.
