    16. Abstract (Limit: 200 words)

    The purpose of this handbook is to provide background information about the importance of pavement preservation andpreventive maintenance, as well as present maintenance techniques for a variety of distresses and conditions. The major focusof this handbook is on preventive maintenance activities, which are performed while the roadway is still in good condition withonly minimal distress, before the pavement falls into a condition where structural overlays, major milling or reclaiming, orreplacement is necessary.

    The most common flexible pavement distresses are cracking, roughness, weathering, raveling, rutting and bleeding. If thedistresses identified in a pavement are related to structural deficiencies, the pavement section is most likely not a candidate forpreventive maintenance treatment, and should be scheduled for rehabilitation or reconstruction. Maintenance treatments coveredin this handbook include: Crack repair w/sealing, including clean and seal, saw and seal, and rout and seal; crack filling, fulldepth crack repair, fog seal, seal coat, double chip seal, slurry seal, microsurfacing, thin hot mix overlays, and potholes andpavement patching.

    Tables are outlined giving the most common flexible pavement distresses, along with the best practices for rehabilitation foreach. Also given are recommended applications for crack sealers and fillers, surface treatments, and pothole patching.Specifications, technical memoranda and special provisions are included for all treatment methods recommended in thehandbook.
