Development of Deterioration Curves for Bridge Elements in Montana
Started: March, 2020 End Date: July, 2022 Project ID #4W8305 Status: Ongoing
Representative deterioration curves specific to Montana’s climate, operation practices, and bridge design details are required to more accurately perform state-wide investment optimization alternatives. In addition, changes to deterioration trends based on maintenance, rehabilitation, or construction practices should be captured to reflect changes to bridge service life. The integration of the refined deterioration curves for Montana bridges must be compatible with a selected bridge management system.
The overall objective of the research is to develop deterioration curves for bridge elements in Montana. Specific objectives are to 1) Create families of deterioration curves for Montana bridges in different geographic locations using explanatory variables such as traffic volume, climate conditions, and design type, 2) Establish modifications to the deterioration curves to represent ‘performance jumps’ in bridge conditions created after maintenance or rehabilitation activities take place, and 3) Create a process to easily revise and implement the data with MDT’s bridge management software.
