“…Currently, there is no uniform approach to the measurement of the friction coefficient, nor to the exact specification of the individual measuring devices. Therefore, a large number of countries or companies involved in surface quality assessment develop their own measuring devices, which often differ from each other, for example, in design, measuring speed, type of measuring tyre used, load on the measuring wheel, thickness of the water film required, slip ratio, slip angle and others [3][4][5].…”

The aim of the paper is to verify the applicability of the T2GO skiddometer for measuring the coefficient of friction for forensic practice in accordance with the legislative framework of the Czech Republic. In the introduction, the article discusses the problem of friction coefficient measurement. The results of the comparison with dynamic measuring devices used in the Czech Republic and the determination of the mutual compliance rate with these devices, based on data obtained within the National Comparative Measurement Action, are presented. The article concludes with an interpretation and discussion of the results. In cases where no sufficient mutual compliance was found, an analysis and reasoning of these results is provided. Last but not least, based on the results, a procedure is proposed for future use of the T2GO skiddometer in practice within the legislative conditions of the Czech Republic.

“…There are other pollutants on the road surface, such as sand, salt, and oil leakage, which will also negatively affect the anti-skid performance of the road [21,22] over a long period of time; as the wheels roll over, these pollutants on the road surface are diffused, leading to compaction, thus blocking the asphalt pavement gaps and reducing the roughness of the road surface, so that the road surface loses its original anti-skid performance, especially in the presence of wind-accumulated sand. In addition, changes in temperature also affect the anti-skid performance of pavements [23,24], and the anti-skid performance in summer is generally lower than that in winter under the conditions of a clean road surface. All of the above are problems faced by asphalt pavement skid resistance performance, the pavement skid resistance performance is vulnerable to the interference of the external environment.…”

In this work, the long-term skid resistance attenuation law of asphalt mixtures in the presence of aeolian sand was studied. Four types of asphalt mixtures underwent skid resistance abrasion tests using an accelerated loading tester. The pendulum value (BPN) and structure depth (MTD) of these four mixtures were determined under various conditions of sand density and abrasion times. The correlation between the BPN and density and the number of times of abrasion were investigated, respectively, to analyze the skid resistance attenuation law at the microscopic and macroscopic levels. Our results indicate that the skid resistance of the four types of asphalt mixtures initially decreased and subsequently reached a stable state. Sand density primarily influences skid resistance during the initial stage, while the number of abrasions becomes the dominant factor affecting skid resistance in the later stages.
