Slide 5 Why Preserve? Slide 6 Pavement Preservation Allows you to change your approach: Look for and correct small problems before they become big ones Eliminate the "worst first" Practice Slide 7 Pavement Preservation Pavement Preservation is efficient, effective and economical. Save money Improve safety Reduce delays Help pavement last longer Improve the performance of the entire road network Slide 8 Doing It Right! The Right Pavement Relying on public complaints is to probably to late. Up to date pavement condition surveys are key Slide 9 Doing It Right! The Right Time Preventative Maintenance needs to be completed in the early stages of the pavements Life. Move preventative maintenance up on the priority list. Slide 10 Doing It Right! The Right Treatment Picking the proper treatment for the right level of distress. Here are some things to consider: Slide 11 Doing It Right! The type of pavement The type, extent and severity of the pavement distress The age of the pavement (or the time since the last major rehabilitation) The type of the road - its use, volume, and traffic speed The availability of qualified contractors, construction technology; materials and qualified agency staff The time of year for maintenance How long maintenance will take and the impact it will have on drivers The pavement quality needed after the pavement has been treated.
