Long-term skid resistance of asphalt surfacings: Correlation between Wehner–Schulze friction values and the mineralogical composition of the aggregates

Wear Analysis of a Heterogeneous Annular Cylinder

“…In the last few decades, many tests have been carried out to study the tire-road interaction, e.g., by changes in the structure of aggregates and asphalt binders [2], and the addition of additives [3]. Recent research [4,5] covers an experimental approach to this contact problem to determine the long-term behavior of different construction materials being exposed to the polishing effects of the tires of vehicles. The behavior of the road material's skid resistance is examined.…”

A study of the laboratory polishing behavior of granite as road surfacing aggregate

“…It then achieves a state of equilibrium which depends on many factors during the in-service life of roads. During the polishing process, the angularity and texture of aggregates changes due to a gradual removal of mineral components [6,7]. Different test methods, for example the polished stone value (PSV) according to EN 1097-8 and the Wehner/Schulze test (W/S) according to the EN 12697-49, are applied to determine the polishing resistance of the aggregates.…”

“…These include the composition of the aggregates and the petrographical parameters of the single minerals, which include the fissility, hardness, sharpness and potentially http://dx.doi.org/10.1016/j.conbuildmat.2015.04.032 0950-0618/Ó 2015 Elsevier Ltd.

Principally, an irregular texture is favored in comparison to a texture with parallel or layered elements (for example mica) [1,20].…”

Construction of Three-Dimensional Road Surface and Application on Interaction between Vehicle and Road

“…However, the fact is that the inadequate description of road surface morphology details by existing road surface spectrum models is restricting the study on vehicle-road interaction. In the field of road engineering, road transportation safety is principally studied from perspective of road skid resistance, and road surface topography is considered to be significantly associated with skid resistance of road surface (Kane et al 2013; [1,2]. Since the shape, size, and distribution characteristics of asphalt pavement texture substantially determine the skid resistance of road surface, rational texture feature parameters help to accurately predict the skid resistance of road surface.…”
