Abstract
The article investigates a method for measuring the evenness of road pavements, which is based on an assessment of the longitudinal microprofile of the pavement, that is, an array of vertical deviations from the horizontal surface of the pavement. Unlike previous methods, which measured the average value of the transverse uneven pavement profile, this method allows you to get more detailed information about the road surface. To measure the longitudinal microprofile of the coating, special equipment is used that can record the vertical deviations of the coating with high accuracy and resolution. The distance between the fixed ordinates can be selected depending on the required measurement accuracy and the characteristics of the road surface. The resulting array of ordinates can be analyzed using various data processing methods, for example, to determine the degree of evenness of the coating, identify the causes of irregularities and plan work to eliminate them. This approach allows you to more accurately determine the quality of the coating and take measures to improve it. The method of measuring the evenness of road surfaces in Northern Kazakhstan, the results of which are presented in the article, is fundamentally different from the previous ones, primarily in that it is based on a new approach, which lies in the fact that the result of the measurement is a longitudinal microprofile in the form of an array of ordinates (amplitudes). The work contains a description of the method and its advantages over previous methods for measuring the evenness of the coating, as well as an analysis of the results and possible practical applications. Thus, this work is of great importance for the transport infrastructure and can be used to improve the safety and comfort of traffic on the roads.
