Bridge deck expansion joints are an important element of bridge structures. When the joints fail to function properly, the performance of bridges can be seriously affected. Numerous research projects have been conducted to investigate the problems caused by the expansion joints and their causes. Some of this prior research was based on field observations while other research utilized in-house laboratory tests. However, a systematic approach to exploring the relationship between the joint condition and the influence of the environmental factors does not yet exist. Also, while the Markov model is frequently used in deterioration modeling, it cannot be applied when the condition rating has only a few levels and is discrete and ordinal. To address these two problems, a methodology is presented that uses the econometric model to predict the joint condition. The joint condition data have three rating levels, i.e., good, fair, and poor; and the ordered probit model is used to estimate the condition by the parameters, including age, traffic volumes, weather, skew angle, etc. Three joint types are investigated in the research: compression seal, strip seal, and integral abutment. The source data are from the 1998 bridge inspection records provided by the Indiana Department of Transportation. The estimation results confirm the findings from the previous field studies as to the parameters' influence on the joint condition. In addition, the results show how the developed deterioration curves can be used for comparing the performance among different types of joints and being incorporated into the life-cycle cost analysis.
