The role of skid resistance of road pavements in ensuring safety of road traffic becomes particularly important when such surfaces become moist or wet. The various types of aggregates and special additives play an important role in asphalt mixtures like SMA, because they fill voids in paving mix and improve the cohesion of asphalt binder. The paper presents the evaluation of skid resistance of five kinds of SMA pavements, during exploitation, based on macro-texture and micro-texture comprehensive analysis. Tests were performed on five research pavement sections made from SMA on roads located in the southern part of Poland. SRT 3 equipment and methodology were used to all estimation of pavement roughness. The micro-texture and macro-texture of asphalt surface in pavements evolve under the influence of traffic and synergistic environmental interaction. The experimental parts of SMA pavements were observed in relevant aspect of skid resistance and durability using electronic microscopy type KEYENCE VHX-6000 Digital. The results of evaluation were compared with data from a literature review.
