Expansion of the Inspection Support Technology Catalog by Japan's MLIT

On April 1, 2023, Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) announced the enhancement of its Inspection Support Technology Catalog designed to improve the efficiency and sophistication of inspections for road infrastructure. The catalog now includes an additional 54 technologies that can be employed for the inspection of bridges, tunnels, earthworks, pavements, and road patrols.

What is the Inspection Support Technology Catalog?

The Inspection Support Technology Catalog is a comprehensive collection that summarizes technologies that can be utilized for the inspection of road structures. It outlines the performance values for standard items set by the government, gathering results from the verification of these technologies on government-managed facilities in a catalog format.

Beginning in fiscal 2022, specific inspection items related to bridges and tunnels were designated for mandatory use of these technologies, followed by pavement assessments starting in fiscal 2023, and road patrol inspections in fiscal 2025. This progressive integration reflects the Ministry's commitment to leveraging advanced technologies to ensure consistent inspection quality and operational efficiency.

Categories of Technologies Added

The newly added technologies are categorized into various fields, reflecting the diverse needs of infrastructure inspections:

• - Bridges, Tunnels, and Earthworks:

- Image Measurement: 141 technologies (16 added)
- Non-Destructive Testing: 75 technologies (6 added)
- Measurement & Monitoring: 99 technologies (9 added)
- Data Collection & Communication: 5 technologies (1 added)

• - Pavement:

- Crack Rate, Ruts, IRI: 55 technologies (15 added)

• - Road Patrols:

- Potholes, Worn Lane Markings, Overloaded Heights, Hidden Signage: 32 technologies (7 added)

Total Technologies Listed

As of April 1, 2023, the catalog has a total of 407 technologies with the newly added 54 technologies enhancing the existing portfolio.

Future Plans

The Ministry aims to continue its outreach efforts to promote awareness of the catalog among stakeholders. Furthermore, it will actively encourage the adoption of these advanced technologies to further the efficiency and sophistication of inspection processes.

In conclusion, the expansion of the Inspection Support Technology Catalog demonstrates MLIT’s dedication to safety and infrastructure management, ensuring that Japan's roadways remain safe and well-maintained for the public. The proactive approach taken to integrate modern technologies into inspection routines promises to enhance the future of transportation infrastructure in the country.
