摘要
As hydraulic analysis technology increases and funds become more and more limited, the investment in culvert pipes becomes more substantial. However, even with this considerable investment, transportation agencies at every level in Wyoming, as well as other states, lack a formal methodology for assessing the condition of culvert pipes. Over time, as these pipes are ignored, they deteriorate without the government agency responsible for them taking necessary maintenance steps. In most cases, deteriorated states are not noticed until a larger problem arises. Counties in Wyoming are currently suffering a lack in funding. With an ample methodology in place, funds could be more adequately appropriated to pipes that are in need of maintenance. A systematic procedure for rating culverts would also aid in obtaining additional funding. Through an examination of the inspection procedures of other agencies across the nation and the Wyoming Department of Transportation's bridge inspection procedure, a comprehensive methodology for obtaining an overall pipe rating was developed. This methodology was implemented in Goshen County in Wyoming as a case study. The information and results from this study will be presented to various entities to facilitate statewide implementation. Local agencies in other states can implement the developed methodology with minor adjustments to reflect local conditions.
