Repeated Diagnostics of Maintained Prestressed Bridge Structure, Interpretation of Changes in Relation to Durability

Abstract

General refurbishment of prestressed reinforced concrete bridge of Pavel Wonka in Pardubice was done in 2006. Within the preparation of refurbishment a full diagnostics of the structure was performed with the assistance of Klokner Institute, including diagnostics of longitudinal prestressed loose cables located in bridge boxes and the real condition of the corrosion was found. New inspection, including water-insulation system and condition of repaired concrete structures was held in 2015. Some of the findings and comparison of the condition before refurbishment and condition after about 10 years of operation are introduced in this article.
