Effects of Pavement Characteristics on Rolling Resistance of Heavy Vehicles: A Literature Review

The effects of pavement characteristics on rolling resistance heavy vehicles have gained more interest in recent years. Rolling is the result combination independent (but sometimes correlated) physical phenomena that dissipate energy, which can be regrouped under three different main themes. Road roughness (wavelengths between 0.5 and 50 m) causes movements vehicle suspensions, energy. Pavement macrotexture mm) creates additional viscoelastic deformations tire treads. behavior flexible structure, referred to as structure-induced resistance, responsible for a perpetual upward slope perceived by tires. Secondary aspects also affect such road wetness snow. This paper addresses each these from angles analysis: (1) theoretical modeling, (2) laboratory experiments, (3) situ measurements. literature modeling extensive compared macrotexture-effect underlying mechanisms are still not well understood. There is, however, strong experimental evidence significantly but studies mostly related cars. many approaches, results usually based an indirect method difficult compare inconsistent. It appears bottleneck scientific research this topic fundamental inability measure with direct approach real driving conditions.
