Developing Deterioration Curves for Bridge Elements

项目名称：	Developing Deterioration Curves for Bridge Elements
摘要：	Bridge management systems (BMSs) in the United States have experienced decades of development. The major player among the systems has been Pontis, now AASHTOWare BrM (BrM). BrM does has a functionality of using collected inspection data to form the transition probability matrix (TPM) as the critical core for forecasting future conditions, based on the Markov Chain model. However, the model assumes a constant TPM over the entire life of the element as well as its memory-less behavior (i.e., the future state depends only on current state but not further earlier states). This process in the software also does not explicitly consider possibly influential variables such as age and traffic but only the condition ratings themselves. The overall objective of this research is to develop reliable deterioration curves based on the element-level inspection data from the Illinois bridge inventory. The resulting deterioration curves will provide the basis for Illinois Department of Transportation to make realistically optimized maintenance, rehabilitation, and repair decisions.
