Improving Efficiency and Sophistication of Tunnel Maintenance
A road tunnel maintenance manual is being created for municipalities in the Hokuriku region. It will consist of four sections: 1) Inspection and measures, 2) Operation abolition and retention, 3) Technical education, and 4) Life extension plans. These manuals will be utilized by road administrators in their operation, ordering, and budget planning. They will also be utilized by practitioners such as consulting companies in carrying out inspections using new technologies and appropriate measures (surveys, monitoring, and repair work).
