The use of FERIC's Opti-GraDE GRADING (EARTHWORKS)-management system is shown toAD ENGINEERING ASSOCIATION OF ASIA AND AUSTRALASIA grading costs by continually measuring the roughness of the road so as to identify sections that require the most maintenance. Managers can concentrate maintenance efforts on those sections. At present, with thirty-four systems are in service across Canada, users report savings in grading costs on the order of 25 percent. It is also shown how Opti-Grade can be used by managers to determine the impact of the road's roughness on travel speeds to identify problem sections as candidates for rehabilitation. A calculation method for the justification of rehabilitation on economic grounds is provided. (Author/publisher) For the covering entry of this conference, please see ITRD abstract no. E208431.
