• Rolling resistance is a prime factor effecting fuel consumption of an ultra class haul truck. Capital intensive mining industry has always been interested to reduce rolling resistance of haul roads thus reducing operating costs by saving fuel.
  In view of the importance of rolling resistance in movement of ultra class haul trucks on haul roads, commonly used materials sand, oil sand, pit run and limestone were tested. Tests were performed with a scaled truck proportionately fifteen times smaller than ultra class haul truck. Oil sand considered as a base material was capped with other materials and tests were repeated. Results obtained from test data was found to be applicable for ultra class haul truck tire and rolling resistance was estimated.
  This research will help in selection of materials for haul roads and quantify rolling resistance in mining industry.
