Analysis of bridge condition on state network in slovenia

Abstract

During operation, bridge condition is decreasingdue to various effects. The condition is described by "condition rating coefficient", determined byvisual assessment Condition of Slovenian state road bridge network is analyzed. The condition rating database is structured with respect to traffic load, climate zone, structural material, structural type and bridge element Changes of condition rating coefficientwith timeare presented and analyzed. Results show that climate and exposure to water are the most important parameters influencing the condition of bridges. Challenges related to assessment methodology are identified and discussed.
