TL;DR: In this paper, the relationship between surface texture and rolling resistance of light and heavy vehicle tyres was investigated and the results of measurements performed by the Technical University of Gdansk show that although the correlation exists, it is not very strong and regression between mean profile depth (MPD) and roll resistance is not linear.

TL;DR: In this paper, the authors present results obtained in the Technical University of Gdansk during laboratory and road measurements of different car tyres rolling on different pavements, showing that while an increase of load always leads to the increase of rolling resistance force, the influence on Coefficient of Rolling Resistance is more complicated and unpredictable.

TL;DR: In this paper, the authors present results obtained in the Technical University of Gdansk during laboratory and road measurements of different car tyres rolling on different pavements, which indicate that generally each tyre and pavement combination is influenced by the air temperature in a unique way, but at the same it is possible to propose some general influence factors that may be used to normalize measurements to the standard temperature of 25 °C.

TL;DR: In this article, the authors used a specially designed trailer to measure rolling resistance on wet roads and an abandoned airfield equipped with water film sensors mounted in the pavement, which indicated strong influence of test speed and water film depth.

TL;DR: In this article, the authors describe the concept of low noise poroelastic road surfaces that are composed of mineral and rubber aggregate bound by polyurethane resin and show that these surfaces have a porous structure and are much more flexible than standard asphalt or cement concrete pavements due to high content of rubber aggregate and elastic binder.
