Effect of pavement roughness on fuel consumption

Highways Members Only

The presentation by Arvo Tinni provides worked examples of fuel efficiency savings with reduced roughness. The basis of the presentation is an ARRB Research Report ARR31, which is based on 7 prior studies. Concluding that a unit change in IRI has an average change in fuel consumption of 1%. The...

Concrete roads save fuel – 2008 Canadian Study

Highways Members Only

Arvo Tinni's presentation references a 2008 Canadian study by the National Research Council, Centre for Surface Transportation Technology. A comparative study of three pavement types - concrete, asphalt and composite. Reported truck fuel savings of 1.8% and 3% at 100km/hr and 60km/hr respectively for concrete when compared with the next...
