MnROAD Research Conference

October 4th, 2011- Minneapolis (Northland Inn Conference Center)

Speakers at the 2011 MnRoad Research Conference presented information regarding pavement materials, design, construction, and rehabilitation ready for implementation within Minnesota and nationally. The sessions focused on recycled materials, pavement rehabilitation, preventative maintenance, long- life performance, surface characteristics, and other research information. The conference also featured a tour of the MnROAD research facility which included visits to selected test sections and demonstrations of various equipment.

Pavement Rolling Resistance

Sept. 14th, 2011- Prof. Jerzy A. Ejsmont, Dr. Grzegrz Ronowski, Technical University of Gdansk Poland (MnROAD Research Facility)

As part of pooled fund study TPF 5-(134) with the participation of Minnesota and Texas departments of transportation and Federal Highway (FHWA), a strategy to measure rolling resistance of all the pavement surfaces at the MnROAD test facility is discussed. Rolling resistance is a pavement surface characteristic that is indicative of fuel efficiency based on tire pavement interaction. On September 14th, 2011 Professor Jerzy(Jurek) Ejsmont presented at the MnROAD research facility at 10:00AM. This presentation introduced new technology that has never previously been used within the United States.

Powerpoint Presentation
