How Road Condition Data Improves Haul Road Maintenance Planning
Road condition data helps mine teams move from reactive maintenance to prioritised maintenance. It shows where haul road condition is deteriorating, which sections are affecting operations, and whether maintenance work is improving conditions over time.
Why haul road maintenance planning is difficult
Haul road networks change every shift. Traffic, weather, drainage and grading all affect surface condition. Maintenance planners often work with incomplete information—shift reports, ad hoc inspections and production pressure to keep roads open.
Without consistent road condition data, it is hard to compare sections fairly, justify grader allocation between competing areas, or confirm that last week's maintenance actually improved the road.
What road condition data adds
Road condition data is repeatable information collected as fleet vehicles travel the haul road network. Proof Engineers' Road Condition Monitoring system processes sensor and GPS data into heat maps, section-level measurements and summary metrics such as Road Score.
That gives maintenance teams a network-wide view rather than snapshots from the sections someone happened to inspect on a given day.
From reactive maintenance to prioritised maintenance
Reactive maintenance responds to the loudest complaint or the most visible pothole. Prioritised maintenance uses road condition data to rank sections by need and operational impact.
Teams can focus grader hours, watercart runs and other maintenance effort on the roads where condition data shows the greatest deterioration or production effect—not just the roads that were reported last shift.
Tracking road condition trends over time
A single inspection shows condition on one day. Road condition trends show whether a section is improving, stable or getting worse across shifts and maintenance cycles.
In a Western Australia lithium mine trial, RCM-driven maintenance was associated with average truck speed +6.6 km/h and overall Road Score +5.2%. In a dig-floor study, targeted maintenance improved road score from 63.79% to 79.13%.

Using road condition data to support grader planning
Road condition data shows where maintenance is needed. Grader Performance Monitoring shows where graders worked and how productively. Together, the two data sets help superintendents align grader deployment with priority sections and review whether grading effort matched the roads that needed attention.
How Proof Engineers supports haul road maintenance teams
Proof Engineers provides Road Condition Monitoring for haul road condition data, heat maps and Road Score benchmarking. Where both systems are deployed, grader activity data integrates with road condition outputs for planning and performance review.
