Traffic safety can be ensured only with a comprehensive understanding of the system driver - vehicle - road environment. Accidents on roads happen due to the driver's actions, errors and problems with the vehicles or happen on account of adverse events in the driving environment. A part of the road safety can certainly be attributed to the pavement surface and its own performance. Particularly important contributing properties are skid resistance and macrotexture.
The aim of the work for this thesis was to determine the influence of crossfall and slope on the results of skid resistance measurements. This impact can be notable and may significantly affect the calculation of the characteristic skid resistance values – the limit, minimal and acceptance values - which are used in the assessement of pavement
performance of roads in Slovenia.
The results of the skid resistance measurements on motorways in 2008, performed with the SCRIMTEX device, served as a basis of the work. These results were compared with the pavement geometric data; with age of asphalt mixtures, built-in the pavement surface; and with traffic load of concerned road sections.
A high number of different combinations of influence on skid resistance for the motorway' pavements were examined. Among them some indicate a weak correlation between skid resistance/influential parameter, and only few indicate a moderate correlation. For vast majority the relationship was found to be insignificant. As such, the results don't represent a momentum strong enough to change or adapt the above-mentioned skid resistance characteristic values.
