BRIDGE LIFE STUDY. FINAL REPORT

The objectives of the research were to identify and quantify the factors that affect the life of South Dakota's bridges, and to evaluate the rehabilitation procedures being used by the South Dakota Department of Transportation (SDDOT). Furthermore, this work was intended to aid in the implementation of a Bridge Management System (BMS). An extensive literature review was performed that included efforts by other states related to BMS. The capabilities of the Pontis BMS software and the information required to utilize this program were reviewed. Elements essential to a BMS, such as level of service goals and user and agency costs for the state of South Dakota, were defined. Finally, deterioration curves for bridge decks, bridge superstructure and bridge substructure considering the effects of ADT, bridge type, geographic location, bridge length, and degree of skewness were developed. The Markov chain statistical approach was the basis in developing these curves. The research demonstrated that South Dakota's present bridge maintenance policy is adequate. In addition, the developed deterioration curves verified that an expected bridge design life of 50 years is applicable.
