Abstract
Taking into consideration the climatic conditions in the Tohoku region, a thermal cracking hazard map and a frost damage hazard map were made using GIS. Then, a data map based on the inspections of 2600 bridges administered by the Tohoku Regional Bureau of the Ministry of Land, Infrastructure, Transport and Tourism, and a data map on deicing salt application volumes administered by the same, were made. The analysis of the deterioration factors for RC bridge decks, RC bridge piers and abutments revealed that these members undergo deterioration under the influence of multiple factors consisting of the number of years in service, large vehicle traffic volume, deicing salt application volume, and average ambient temperature in winter. The tool created as detailed above was found to be useful for bridge management by local governments in the Tohoku region.
