As the challenges associated with managing a low-volume road network increase, agencies have realized the benefits associated with the use of pavement management tools for the road network. One of the benefits of the use of these tools is the ability to illustrate quickly and effectively the impacts of various pavement preservation strategies (such as worst-first repair) on overall network conditions. As a result, agencies are in a better position to communicate the needs of the road network to individuals responsible for the allocation of funds. In some cases, agencies have successfully lobbied for additional funds to support their road management efforts. The benefit of pavement management tools in supporting the preservation of the low-volume road network is illustrated by their use in evaluating the long-term impact of various funding strategies, the cost-effectiveness of pavement preventive maintenance programs, and various cost analyses that can be used to enhance road system management. Information from a variety of transportation agencies is used for this illustration. For instance, a summary is presented of the use of pavement management information to compare a worst-first repair strategy with a strategy that includes pavement preservation techniques. Examples are provided of the types of presentations that can be given to top management to illustrate these effects. In addition, the cost-effectiveness of pavement preservation programs is illustrated by showing the reduction in life-cycle costs and the overall benefits provided to the agency through the implementation of preventive maintenance programs.
