This database is composed of topographies of three mosaics of three different aggregates at three different polishing stages. Each topography is two different formats: “sur” and “txt”. The “txt” format is composed of 15 parallel profiles separated by 0.5 mm. Each profile has a length of 76 mm. Each two points of the profile are separated by 0.01 mm. The three circular mosaics of 22.5 cm diameter are made from three different aggregates: Limestone, Basalt, and Granite. They have been prepared by placing the 7.2-10 mm size fraction of the aggregates in a single layer as closely as possible, with their flattest faces lying on the bottom of a mold and then filling the mould with a resin. The polishing process is made using the dedicated head of Wehner-Schulze machine. The polishing head contains three rubber cones mounted on a rotary disc. It is the loaded and rolling action of these three cones on the pavement surface that produce the effect of polishing. To accelerate the polishing, a mix of 5% quartz powder in 95% water is sprinkled during the rotations of the cones. Texture has been captured using a laser scanning profilometer before, and after 90,000 and then 180,000 cycles of polishing. The measuring area is located inside the polished ring of the pavement.
