• Abstract:
  This project resulted in the development of a framework for making asset management decisions on low-volume bridges. The ; research focused on low-volume bridges located in the agricultural counties of Iowa because recent research has shown that these ; counties have the greatest percentage of structurally deficient bridges in the nation. Many of the same counties also have the ; highest crop yields in the state, creating a situation where detours caused by deficient bridges on farm-to-market roads increase ; the cost to transport the crops. Thus, the research proposed the use of social return on investment (SROI), a tool used by ; international institutions such as the World Bank, as an asset management metric to gauge to the socioeconomic impact of ; structurally deficient bridges on the state in an effort to provide quantified justification to fund improvements on low-volume ; assets such as these rural bridges. The study found that combining SROI with current asset management metrics like average ; daily traffic (ADT) made it possible to prioritize the bridges in such a way that the limited resources available are allocated in a ; manner that promotes a more equitable distribution and that directly benefits the user, in this case Iowa farmers. The result is a ; system that more closely aligns itself with the spirit of MAP-21, in that infrastructure investments are used to facilitate economic ; growth for Iowa’s agricultural economy.
