Testing and analysis of the elements of the high-risk road section concerning the quality of the pavement curtain and its impact on the value of the adhesion coefficient

Abstract

In the structure of factors on which traffic safety depends, road and road elements occupy an important place in the traffic safety management system. The elements of the road create the conditions for the danger caused by other elements to turn into a traffic accident. Road elements can affect the occurrence of traffic accidents, but in particular, they can affect the "weight", i.e. the result of a traffic accident. This statement is supported by the fact that there are a number of influential elements of the road that can be direct or indirect causes of traffic accidents. The condition and quality of the roadway affect the safety of the traffic as a direct factor. The paper emphasizes the quality of the carriageway curtain and the analysis of the impact of the same on the value of the adhesion coefficient. The value of the adhesion coefficient is determined by practical measurement with a pendulum (Skid Resistance Taster) on parts of a high-risk section of the main road, in order to achieve its satisfactory quality, i.e. satisfactory grip coefficient.
