This paper shows a new approach to the problem of rehabilitation and widening of bridges. Some unique factors are being employed to improve the Indiana Toll Road. The first requirement for the design was to keep two lanes in each direction during the whole construction process minimizing the traffic impediments so the complete demolition of structures was not an option. Therefore a very important engineering effort has been done. After a careful identification of the pre-existing damages, the right treatment was implemented in each element taking into account a life expectancy of 50 years. A special treatment against damages produced by de-icing salts has been designed using cathodic protection to avoid cell effect. Each stage of the construction process for the widening has been analyzed coordinating geometrical and structural conditions with traffic management. |
