Road management system creates more fuel savings and cost reductions for mine roads

As well as being a major maintenance and safety factor, poor quality roads are proven to adversely affect fuel economy and total road user costs.

In a special study commissioned by Dust-A-Side and conducted by leading tyre manufacturer, Michelin, at their cutting edge mining test centre in Spain, the impact of Dust-A-Side’s Haulroad Management System on the fuel consumption of rigid dump trucks was assessed.

The results were quite impressive, however for those familiar with Dust-A-Side’s Haulroad Management System, hardly surprising.

The test conditions were set to a reduced scale automated truck, at constant speed, with a pulling effort simulating a constant slope of 10% and on stabilised operating conditions.

When comparing a stone-covered (untreated) reference track and a Dust-A-Side treated track, a substantial reduction in fuel consumption of 7.5% could be measured.

Uncertainties linked to the extrapolation to real-life operations, with different trucks and variable speeds and slopes, led Michelin to a reasonable conclusion that the overall reduction in hourly fuel consumption is 3% on average.

The reduction in fuel consumption observed by Michelin can be directly attributed to the reduction in Rolling Resistance realised with Dust-A-Side’s road management system.

Independent Study

An independent study undertaken by RoadSafety Training Services at a mine in Queensland found that, “A Dust-A-Side treated sealed surface improved rolling resistance compared with unsealed surfaces; potentially in the order of 20-30% compared with a competent unsealed haul road.”


A similar study conducted over a 4-month evaluation period found that a Dust-A-Side road reduced the measured International Roughness Index (IRI) by almost 40% compared with an untreated control section of the same road, as shown in this chart.

Now it is widely accepted in the construction and mining industries that there is a strong correlation between Rolling Resistance and FuelConsumption. However, Rolling Resistance also directly affects haulage production performance as can be seen in this chart. As Rolling Resistance increases, production efficiency reduces.

Contact one of Dust-A-Side Australia’s engineers today on 1800 662 387 to determine the cost savings that can be realised at your operation through a reduction in haul road Rolling Resistance.

We will use a total road user cost analysis that considers the impact of rolling resistance upon:

  • Fuel costs
  • Cost per tonne hauled (productivity)
  • Tyre costs (wear rates and premature failures)
  • Equipment and maintenance costs (wear and fatigue)
