Choosing a Pavement Preservation Technique

This article, from a series of articles on pavement preservation, walks readers through the process of choosing a pavement preservation technique. The author first defines pavement preservation as a proactive approach to protecting and maintaining existing pavements. The author presents the approach used by Maryland Department of Transportation (DOT), stresses that there is some basic information necessary before an appropriate technique can be chosen. Having a good understanding of the current pavement condition is essential, with a focus on the type and severity of existing problems. The author recommends the manual that came from the Long Term Pavement Performance (LTOO) study as a good distress identification manual. Engineers should also know the amount and type of traffic traveling the pavement under consideration, as well as the types of contractors who may be available to help with pavement preservation. The remainder of the article defines and describes different types of pavement treatment options, including crack sealing and filling, chip seals, micro-surfacing and slurry seals, and thin overlays.
