Abstract [en]

Edge beams in Sweden are subjected to harsh environmental conditions, such as de-icing salts

and numerous freeze-thaw cycles, which result in large expenditures for the maintenance of

these items. Driven by that fact, a project was initiated to investigate the life of edge beams in

more detail.


The main objective of the work was to determine and provide reliable input for establishment

of investment cost of edge beams. The data was later utilized in an application of life-cycle cost

analysis - created by a Ph.D student. Case studies - ongoing bridge construction projects in

Askersund, Rotebro and Kallhäll - gave the basis for the research. Site visits were performed

and engineers were consulted for data collection.


As an outcome of the project, costs for the edge beams in the case studies were calculated and

comparative charts were presented that reveal the magnitude of cost contributors to the bridge

edge beam system.


The work illustrates that the construction of edge beams is a workforce demanding process.

Hence it is suggested that, to find the most optimal edge beam solution in terms of investment

cost and life-cycle considerations, various construction methods such as prefabrication of edge

beams should be tested and analysed.
