You are here Road Surface and Roadbed

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.
