Owing to their cost-effectiveness and longevity, the popularity and the use of rollercompacted concrete (RCC) pavements have grown in Turkey both on urban and rural roads in recent years. Despite the vast amount of research on the mechanical and durability properties of RCC pavements, few studies have been conducted to examine the surface texture characterization, which impacts driving comfort, fuel economy, and safety. This study aims to investigate the effects of the RCC mixture proportions on the macro- and micro-texture characterization of RCC pavements. Therefore, RCC samples were prepared using various cement dosages, aggregate gradations, water contents, and compaction degrees. The British Pendulum Test and sand-patch test, two conventional indirect methods, were initially used to assess micro- and macro-texture properties. The surface characteristics of the RCC pavements were then measured using a novel 3D photogrammetry technique that was created and utilized for the first time. The most significant result of this study shows that both smaller and larger aggregate sizes, in combination with an ideal water content of 5%, significantly enhance the macrotexture and skid resistance in RCC pavements, offering crucial information for pavement designers. Strong correlations between the important texture parameters were observed in these ideal mixtures, which also exhibited smoother surface textures and more uniform mixtures. The results of this study will help to improve RCC pavement mix designs, which will ultimately improve driving comfort and road safety.
