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.
