Abstract:The South Dakota Department of Transportation (SDDOT) has been using pavement management practices for nearly 30 years, when the agency established its Rural Planning Inventory System to assess needs based on a Pavement Serviceability Rating. A Pavement Management Task Force was established and new pavement management software was implemented as a result of SDDOT Research Project SD1993-14, Enhancement of South Dakota’s Pavement Management System. Since then, a number of internal and external factors have impacted the effectiveness of the Department’s pavement management process. For example, funding levels are expected to decrease dramatically in coming years. Coupled with significant increases in material costs, the Department does not expect to be able to pave as many miles of pavement as in the past. In response to this situation, the Department has initiated a pavement preservation program targeted at slowing the rate of pavement deterioration and keeping good roads in good condition for a longer period of time. While the implementation of the pavement preservation program is an important step, other enhancements to the pavement management process were sought to further improve the effectiveness of the SDDOT’s decision process.
