Tire/Road Rolling Resistance Modeling: Discussing the Surface Macrotexture Effect

This paper deals with the modeling of rolling resistance and analysis effect pavement texture. The Rolling Resistance Model (RRM) is a simplification no-slip rate Dynamic Friction (DFM) based on tire/road contact intended to predict tire/pavement friction at all slip rates. experimental validation this approach was performed using machine simulating tires road surfaces. tested surfaces have wide range textures from smooth macro-micro-rough, thus covering likely be encountered roads. A comparison between resistances those predicted by model shows good correlation, an R2 exceeding 0.8. correlation MPD (mean profile depth) also shown. It noticed that random distribution pointed shape summits may inconvenience concerning resistance, leading conclusion beyond macrotexture, positivity texture should taken into account. possible neglecting damping part in constitutive rubber noted.
