? 2022 Elsevier LtdThis study focuses on dry wear of the surface of a cementitious materials loaded with a spinning wheel. This type of phenomenon is popular in surfaces when vehicles are starting to drive. The novelty of the article is to design and create a novel test stand to investigate this type of wear. In this study an automated portable noncontact three dimensional (3D) Light Amplification using the Stimulated Emission of Radiation (LASER) scanning technique and scanning electron microscopy (SEM) imaging were applied to determine the surface morphology during the analyzed wear mechanism. The most pertinent discoveries were visualized in the form of 3D isometric images and showed more intense destructive mechanism in the surfaces morphology while the wheel was spinning longer, which was represented by the decreasing volume of peaks at approximately 20%. This phenomena was strengthened with the extensive increase of the temperature of approximately 80 °C after 25 s. The model of the dry spinning wear mechanism was proved tests conducted by the SEM. Finally, the dry spinning wear process was divided to three stages distinguishing changes occurred in the near-surface area.
