Описание: Preventive Maintenance: Project Selection -- Right Road, Right Treatment, Right Time - Federal Highway Administration - Video VH-411 - A good, modern video that emphasizes the importance of preventive maintenance. It discusses pavement condition surveys using moving vehicle visual inspections to catch signs of distress early. Short interviews with state DOT personnel include Caltrans key maintenance people Larry Orcutt, Tom Pyle, and Gary Hildebrand. Although emphasis is on state activities, the video could be valuable for larger city and county maintenance programs and as a tool to convince public decision-makers of the value of preventive maintenance. The video refers to crack/joint fillers, chip seals, slurry seals, fog seals, microsurfacing, asphalt/rubber, pavement overlays, dowel bar retrofitting in PCC pavements, and pavement recycling. Emerging technology such as Cape Seals, multiple seals in one application, and polymer seals and systems are discussed.
