2018 Since fiscal year 2017, we have been carrying out trial construction of simple repairs on short span bridges managed by Toyama City.This simple repair focuses on short time, low cost, and simple work, and meets the needs of municipalities in the Hokuriku region, and a system has been established in which local government officials and experts (university and technical college teachers) regularly evaluate the effectiveness of repairs. We are working to popularize simple repairs by analyzing and evaluating the workability and repair effects suitable for short span bridges in the Hokuriku region, including this trial construction.
