Toward the Determination of the Appropriate Capturing Resolution of Surface Textures in Relation to Pavement Friction

“…Then, in a second step, from these measured textures, different new resolutions are created by resampling. The friction of these resampled textures is calculated using the dynamic friction model (DFM [8][9][10][11][12][13]), a model already validated. In a third step, a comparison between calculated friction (with the DFM) and the experimentally measured friction on the set of pavement surfaces are conducted in order to determine which of the resolutions (obtained after resampling) allows the most accurate prediction.…”

“…The DFM or dynamic friction model is a friction model of a rubber pad/pavement based on the modeling of the contact of these two bodies [8][9][10][11][12][13]. This model considers the type of rubber, the roughness of the road, the level of wetting and the operating conditions (load, sliding speed, etc.).…”

“…(This adhesion friction coefficient corresponds to the optimum value which, inputted to the DMF, outputs the best prediction of the experimental friction.) [8][9][10][11][12][13].…”

Influence of Morphological Characteristics of Coarse Aggregates on Skid Resistance of Asphalt Pavement

“…In the meantime, researchers believe that the type, apparent morphology and mineral composition of aggregates in the surface layer of pavement play an important role in the formation of surface texture [5,[10][11][12][13]. Based on the skid resistance measurement results in the laboratory, researchers have pointed out that the anti-skidding performance of asphalt pavement depended on the effective friction and texture depth of the pavement [14][15][16][17]. Besides, using steel slag and other materials with high wear resistance as the aggregates to prepare asphalt mixtures or construct asphalt pavement can also improve the skid resistance [18][19][20].…”
