A road surface management system is capable of detecting road surface conditions that tend to damage dump trucks and displaying the positions of such road surfaces. When the traveling speed of the dump truck is higher than or equal to a preset threshold value, the server judges whether or not each of the pressures of suspensions of the dump truck detected by pressure sensors is within a reference range which has been set corresponding to each suspension. The server judges that the road surface at the position of a dump truck is in a poor condition if one of the pressures of the four suspensions of the dump truck is judged to be outside the reference range and the remaining three pressures are judged to be within the reference range. The positions of the road surfaces judged to be in the poor condition are displayed on an indicator. |
