Rolling Resistance Measurements at the MnROAD Facility, Round 2

Status:  Complete
Report Date:  08/28/2014


MnDOT collaborated with Minnesota State University, Mankato, and the Technical University of Gdańsk, Poland, to conduct a second study of rolling resistance at the MnROAD pavement research facility and to evaluate the relative fuel economy of various pavement surfaces. Results showed that pavement surfaces with higher rolling resistance coefficients and energy consumption were those with greater amounts of surface texture, such as porous asphalt, conventional diamond grinding and exposed aggregate. Pavements with lower rolling resistances tended to be asphalt pavements with dense graded aggregates and concrete pavements with broom or turf drag surfaces.
