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.
Step Frequency Ground Penetrating Radar
Sept. 14th, 2011
MnROAD Research Facility
Step Frequency Ground Penetrating Radar is a non-destructive testing technology that FHWA has been evaluating and developing for use in the U.S. This technology has the ability to provide 3-D imaging, continuous calibration, and more detailed assessment of in-situ conditions such as AC stripping, layer debonding and moisture detection, in addition to pavement layer thickness.
Tom Yu of FHWA gave a brief, informal presentation on results from testing in Minnesota followed by demonstration of the technology.
