道路構造物メンテナンスの セカンドステージへ

摘要

In Japan, inspection manuals for roads and road-related structures have been produced, and regular inspections have been put into full practice since 2014. Today, road maintenance is about to enter the second stage, in whicn inspections and repairs will be constantly executed and more efforts will be made for longer structural life and further cost reduction by means of the introduction of new technologies. This report presents current and prospective efforts in this area by the National Institute of Land and Infrastructure Management. The primary focuses include the basic concept of inspection manuals for each road structure, research on systematic repair and reinforcement design, future directions regarding the use of new technologies, and efforts in introducing them to actual construction.%平成26年度以降、各道路構造物の点検要領を整備し、定期点検が本格化されてきた。今後、メンテナンスのセカンドステージとして、点検 や補修を着実に実施していくとともに、新技術の導入等による長寿命化•コスト縮減に取り組んでいく必要がある。これらに向けた国総研の 取り組みや今後の方向性を展望する。具体的には、各構造物の点検要領の考え方、合理的な補修•補強設計法の研究、新技術活用の方向性と 現場導入への活動を紹介する。
