The paper deals with the variation of tire/road friction with thin water depths and the effect of road surface microtexture. Tests are performed in laboratory on slabs...

Road surface microtexture (sub-millimeter scale) is essential for pavement skid-resistance. However, its measurement is only possible in the laboratory on cores taken...

This paper deals with the contribution of road surface microtexture to the relationship between tire/road friction and water depth. The main objectives are the...

Nous étudions les revêtements routiers dans un objectif de sécurité et de suivi de leur dégradation au cours du temps à partir de l’analyse des microrugosités de la...

In this paper, validation of a contact model for the prediction of low-speed friction from road surface microtexture is presented. The aim is to couple later this...

Tire/wet road friction depends on two road-surface texture scales: the macrotexture (centimeter- to millimeter dimensions) is responsible for the speed dependency of...

The paper dealt with the use of geometric parameters to measure the degree of polishing of road surface aggregates. Microtexture asperities were characterized by two...

Road-surface microtexture (sub-millimeter scale) is essential for pavement skid-resistance. However, its measurement is only possible in laboratory on cores taken from...

L'article présente les résultats d’une part sur la détermination de descripteurs pertinents permettant d’étudier l’influence de la microtexture des revêtements de...

In this paper, validation of a model for the speed dependency of friction is presented. Based on the shape of the friction – speed curve, the model assumes that...

Skid resistance, on which road safety depends, is closely related to the road surface texture and particularly to its microtexture. The microtexture is defined as...

This paper dealt with a laboratory study on the effect of the polishing process on the road aggregate microtexture. The polishing action was simulated by the...

Development of a device for measuring road surface microtexture and the determination of a microtexture parameter related to wet road/tire friction are discussed. A...

The viscoelastic deformation of tire rubber by road surface asperities was modeled by the rolling contact between a Kelvin solid and a surface motif, which is the part...

Both tire wear and road polishing are complex phenomenon, which are obviously strongly related; the energy that polishes the road is the energy that wears the tire....

Skid resistance, whilst being complex, is one of the more controllable factors that road engineers can design and modify to reduce the number of wet pavement and loss...
