The ASCP forum on Industrial Pavements provided valuable information on design, detailing, materials and construction issues related to industrial pavements. It also highlighted several differing opinions and challenges to existing practices. This forum was also timely in relation to the planned review of its industrial pavements design and construction guides...

Effect of pavement roughness on fuel consumption
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
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...

Concrete Industrial Pavement Design
This forum addressed both concrete road pavements & concrete industrial pavements. Presentations made addressed concrete mix designs, design & construction aspects, as well as current information about diamond grinding of concrete road pavements in Australia. Concrete Industrial Pavements: Client requirements Pavement guidelines Subgrade and sub-base Design methods Flatness and levelness...
Movie – Concrete Joint Cracking Machine Concrete roads and industrial pavements
This forum addressed both concrete road pavements & concrete industrial pavements. Presentations made addressed concrete mix designs, design & construction aspects, as well as current information about diamond grinding of concrete road pavements in Australia. The video demonstrates the use of an innovative machine to effect concrete pavement jointing.
