Abstract [en]

Gervasio H. et al [1]in there comparative life cycle analysis of an integral abutment composite bridge and concrete bridge have established the advantages of integral bridge due to its limited initial construction cost and maintenance and repair costs during its life cycle. This paper is based on the same data with a modification to the life cycle cost analysis of the bridge by using an inflation adjusted discount rate. In standard bridge structures, expansion joints are one of the most expensive components to maintain. In this regard, joint less bridge have major advantages. Integral bridges are built without joints, they span from one abutment to the other abutment, possibly over intermediate piers, without any joints in the deck. The absence of joints and bearings results in savings in initial costs and reduce maintenance efforts. Apart from economic benefits, the reduction of maintenance leads to less disturbance of the traffic over the bridge and thus to smaller environmental and social impacts. In this paper a case study is presented with the purpose of making a comparative life cycle analysis between an integral composite bridge and a concrete bridge with expansion joints. The result of this life cycle analysis will enhance the advantages of the former solution in regards to the economic and environmental aspects.
