Study on micro-texture and skid resistance of aggregate during polishing

Zhenyu QIAN, Lingjian MENG

Frontiers of Structural and Civil Engineering 2017, Volume 11, Issue 3, Pages 346-352 doi: 10.1007/s11709-017-0409-7

Abstract: The skid resistance performance of pavement is closely related to the micro-texture of pavement aggregate, while there is very few research on the relationship between micro-texture and the skid resistance.Based on the results of independent T-test and the polishing resistance analysis, it shows that the surfacesurface ( ) and the mean summit curvature ( ) are selected to describe the characteristics of aggregate micro-textureThe contribution of micro-texture to the skid resistance can be described with the secondary polynomial
