The significant impact of surface roughness characteristics on determining the friction of bodies in tribo-systems is well recognized. The link between road pavement macro/micro-roughness and friction calls for surface roughness indicators that could best describe the multiscale nature of the road top topography, where the actual contact occurs. In this manner, a thorough field experiment was conducted on existing road pavements to elucidate qualitative link between scale independent roughness parameters and road pavement friction at actual road conditions. But the exploration of the exact connection between macro/micro-scale roughness and friction is not feasible at field conditions. Hence, experimental work was extended to a set of laboratory examinations to enforce control over texture parameters. Here, 3D printing technology was utilized to generate artificial geometries with carefully selected surface characteristics on the basis of the random process theory and fractal modelling. Sliding friction experiments on the printed surfaces demonstrated that this novel method can improve our understanding of the texture impacts on friction.
