Significant increased demand in heavy traffic loads towards heavy and long vehicles on roads could lead to an increase rate of bridge structural deterioration. This paper presents a methodological framework which can be utilized to estimate deterioration rate of a bridge using accelerometer sensor measurements. Deterioration rate is quantified using changes in natural frequencies of the bridge because it correlates with the reduction in structural capacity of a bridge. Using a case study bridge in Aceh Indonesia, the results of study show that dynamic monitoring framework using accelerometer sensor can be utilized to estimate deterioration rate of a bridge and ultimately it can be further used in the prediction of bridge residual life.
