Joint improvements of skid and abrasion resistance of concrete pavements through manufactured micro- and macro-textures

Pavement surface texture is crucial for skid and abrasion resistance, influencing traffic safety throughout a roadway's lifespan. Traditional texturing methods often yield random patterns, hindering consistent high-performance textures. However, 3D printing technology enables the creation of custom, precise, and uniform textures on concrete pavements. This study evaluated 26 3D-printed concrete pavement texture configurations for their skid and abrasion resistance and their relationships with surface topography and materials. Results show that micro-texture wavelengths of 125.6–500 μm significantly impact both low-speed and high-speed friction, while wavelengths of 62.8–125.6 μm are vital for high-speed friction. Additionally, appropriate aggregates like emery enhance skid and abrasion resistance, improving the performance of these manufactured textures.
