The Minnesota Department of Transportation and Minnesota State University, Mankato, contracted with the Technical University of Gdansk, in Poland, for a second time to conduct rolling resistance at the MnROAD facility near Albertville, Minnesota. Rolling resistance testing was conducted on most of the cells of the MnROAD mainline and the low-volume road. A relative ranking of rolling resistance among the difference surfaces at MnROAD was developed. The research team from Poland conducted the testing for a week in early May 2014. The rolling resistance data collected were analyzed and are presented in this report. Additional analyses that were conducted include a relative comparison of fuel consumption predicted with the different rolling resistance coefficients measured at MnROAD, with standard concrete and asphalt pavements as references.
