KIOSK collects and organizes basic technologies from all fields that contribute to Maintenance.
For maintaining roads, it is important to monitor the changes quantitatively that have occurred not only in the road itself, but also in the surrounding ground and slopes.
Monitoring data will be essential for establishing the proper maintenance planning.
In addition, it is necessary to have a warning system such as for traffic restriction in case of emergency.
For this purpose, monitoring technology is important, and many monitoring methods are described in the content here.

Since, the total length of the road is long, road maintenance is generally expensive and time-consuming matters. Because of the limited budget for maintenance, it is essential to identify severely damaged areas of the road to determine the priority zone for the maintenance when making the maintenance plan.
For evaluating the road surface and roadbed condition various inspection and diagnosing techniques have been developed.
As the inspections and diagnoses are carried out regularly, acquired data should be accumulated in a database or cloud-based data storage system. This is important for maintenance for the long term.
The bridge consists mainly of iron and concrete. In the case of bridges where those are constructed along coastal areas, it is necessary to take into account chemical erosion of the materials due to chloride damage.
By observing the presence of cracks on the bridge structure, chemical analysis of the material, stresses which apply on the structure, etc. the bridge can be quantitatively assessed.
Recently BIM is utilized for construction works, these data are expected to be reflected in BIM. Then the maintenance planning and works would be performed effectively.
Tunnel is mainly constructed in mountainous area and underground in urbanized areas. Since, the surrounding geology varies from hard rock to soft soil, the design of the tunnel is varied.
But in any case, a tunnel should have enough strength against underground pressure or dynamic forces caused by earthquakes.
In addition, in case of fire caused by a traffic accident, fireproof measures should also be considered.
Slope measures aim to stabilize the slope itself to prevent the failure of the slope. To achieve this, monitoring is quite essential to grasp the condition of the slope.
Many monitoring technologies could be applied for slope. Since the observed area is wide, a huge volume of the observed data should be interpreted in real time. The interpretation using AI technologies would be next generation techniques for the future.
Since, the total length of the road is long, road maintenance is generally expensive and time-consuming matters. Because of the limited budget for maintenance, it is important to identify the location and condition of the road structure where it is severely damaged.
For evaluating the road structure, inspection and diagnosing techniques have been developed.
These techniques are effective for maintenance work for the long term.
