3D Road Surface Model for Monitoring of Transverse Unevenness and Skid Resistance

The qualitative characteristics of pavement in a wide range reflects the pavement serviceability, which is a summary of the characteristics of the pavement, providing a fast, smooth, economical and especially safe driving for motor vehicles. The target factor of pavement serviceability and safety of roads represents the quality of their surface properties. Within the Research Center of the University of Zilina researchers are scanning the pavement surface in order to monitor the individual parameters of pavement serviceability. This paper deals with the creation, analysis and evaluation of a 3D road surface model in terms of two properties of pavement serviceability: the rut depth and its texture. Measurements are realized on an experimental field with accelerated straining on the pavement (loading wheel). The long-term accent should be mentioned for its prediction functions of selected pavement serviceability parameters.
