Modern Highway Bridges are designed and built to last at least 75 years. Once a Bridge is designed and constructed, it is open to the traffic and it starts carrying actual vehicle loads. However, because of environmental factors (i.e. corrosion) and increase in traffic load, deterioration of bridge members are usually observed before the bridge reaches mid-life. Therefore the design cannot guarantee a life long safety. In order to insure the safety of the bridge under operating conditions, bridge condition must be evaluated periodically.At that time, however, State Departments of Transportation (DOTs) were still using load factor design or allowable stress ... In 1994, AASHTO published the Manual for Condition Evaluation of Bridges to replace the Manual for Maintenanceanbsp;...
