Study of the skid resistance of blends of coarse aggregates with different polish resistances

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

“…Skid resistance mainly depends on the micro-texture and macro-texture of the road surface and is influenced by the roughness, choice, grain size, arrangement and grading of the aggregates [1][2][3][4][5]. The skid resistance of roads generally decreases with the polishing process of aggregates due to traffic loads [1,5].…”

An Investigation of the Polishing Behavior of Calcined Bauxite Aggregate

“…The physical properties of basalt and limestone aggregates meet the Chinese standard specifications (JTG F40-2017) for the construction of highway asphalt pavements, as shown in Table 2. PSV test was used to evaluate the skid resistance coefficient of aggregates using in the pavement surface coatings [13]. The PSV test of aggregates was usually divided into the following three steps according to Chinese standard JTG E42-2005 [14].…”

Influence of the gritting material applied during the winter services on the asphalt surface performance

“…The macro-texture is characterized by surface irregularities with dimensions ranged between 0.5 and 50 mm horizontally and between 0.1 and 20 mm vertically (Forschungsgesellschaft für Straßen-und Verkehrswesen (FGSV) et al, 2012;Wilson, 2006). The micro-and macro-texture of a road, which have a significant impact on the activation of the frictional force between vehicle tires and road under wet conditions, are influenced by the roughness, choice, grain size, arrangement and grading of the aggregates (Forschungsgesellschaft für Straßen-und Verkehrswesen (FGSV) et al, 2012;Ech et al, 2012;Senga et al, 2013;Wang et al, 2014a).…”
