1 Validation model for service life prediction of concrete structures A. van Beek

Most bridges in the highways of the Netherlands are designed to last 80 years. In those 80 years only minor damage should be repaired. To determine the repair strategy of these minor damages the so-called Lifetime Extending Maintenance model can be used. This model is a condition model, which has been used for many materials like paint on steel [1]. In this paper we will show an application of this model with which the repair strategy of concrete structures has been validated. 1
