CORROSION CONDITION EVALUATION AT MUDDY CREEK BRIDGE

Corrosion rates were measured at the exposed spots of rebars near 3 corners of Muddy Creek Bridge located in northern West Virginia using a 3LP device. Also, chloride contents of the concrete samples taken from the vicinity of the spots were analyzed using a wet chemical method that had been developed in this study. The average corrosion rate over the 3 spots was 4.66 mA/m sq, which is in the range of corrosion damage possible in 10-15 years. The average chloride content of the concrete over the 3 spots was 703 parts per million (ppm), which is well above the threshold limit value of 260 ppm. Although the corrosion rate measurement method using a 3LP device is by manual operation, it is found to be reliable and effective, and, thus, recommended for future studies of this kind of research. The wet chemical method developed in this study was found to be effective.
