What Is Haul Road Condition Monitoring?
Haul road condition monitoring gives mine teams a repeatable way to measure the condition of mining haul roads—not public highways—using data collected as fleet vehicles travel the network. It helps maintenance teams move from subjective, point-in-time checks to consistent road condition information they can use for haul road maintenance planning.
Why haul road condition matters
Haul roads carry production traffic every shift. Poor surface condition increases rolling resistance, affects tyre life and can reduce travel speeds across the mine. When teams lack objective data, maintenance effort may be spread unevenly or directed by inconsistent reporting.
Road quality monitoring on haul roads helps teams see where condition is deteriorating so maintenance can focus on sections that affect production and safety most.
What haul road condition monitoring measures
Haul road condition monitoring measures how haul road surfaces respond as vehicles travel them. Proof Engineers' Road Condition Monitoring system uses vehicle-mounted sensors and GPS location data to build a picture of road condition across the network.
Outputs include road condition heat maps, section-level condition data and metrics such as Road Score that summarise road quality monitoring results for benchmarking and trend review.
How haul road condition monitoring works
Mining haul road monitoring typically follows four steps:
- Sensors on fleet vehicles collect movement and location data as trucks travel haul roads.
- Data is uploaded and processed into road condition information.
- Road condition is visualised on maps and dashboards for the site network.
- Maintenance teams use the output to prioritise haul road maintenance where it matters most.
Why manual inspections are not always enough
Manual mine road inspections remain valuable for on-ground context and local judgement. However, they can be subjective, vary between inspectors and shifts, and cover only the sections visited on a given day.
On large haul road networks, it is difficult to maintain consistent coverage and to compare results over time using inspections alone. Haul road condition monitoring adds repeatable, network-wide data to support those inspections.
How mine sites use road condition data
Teams use road condition data to:
- Identify deteriorating sections sooner across the full network
- Prioritise haul road maintenance between competing road sections
- Track whether road quality is improving after maintenance work
- Support discussions between mine services, production and maintenance planning
Existing Proof Engineers deployments include a Western Australia lithium mine trial where RCM-driven maintenance was associated with average truck speed +6.6 km/h and overall Road Score +5.2%, and a dig-floor study where targeted maintenance improved road score from 63.79% to 79.13%.

How it supports grader planning
Road Condition Monitoring shows where maintenance is needed. Grader Performance Monitoring shows where graders worked and how productively. Together, road condition data and grader activity data help teams align maintenance priorities with grader deployment and review whether grading effort matched the roads that needed attention.
