1.4.5.5 Road Structure

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.
