Targeted Sanding and Its Impact on Heavy Hauler Pull Force and Surface Friction

Abstract

Road conditions during wintertime in northern Norway frequently cause problems for heavy haulers transporting goods. The trucks often experience difficulties when traveling uphill or downhill because of snowfall and ice formation, which again constitutes a safety risk and a nuisance for other road users. In this paper, we report on a series of field tests in which we investigated the impact of targeted sanding on a heavy hauler with a focus on self-help, pull force, and road friction.
