The Usability of Different Skid Resistance Characteristics in Road Assessment

The article was created as a reaction on the request of the Slovak Road Administration, whether it would be possible to evaluate level of friction on the road network only by using laser equipped device Profilograph GE, instead of by using longitudinal friction coefficient measuring device Skiddometer BV11, which is slow, much more difficult on operation and it is necessary to fulfil the water tank for measurements. In order to find out the answer, there were evaluated measurements performed on road sections in Slovakia for the past few years. The main goal was to compare results obtained by both devices, and to find a relevant correlation between them. For better understanding of the problematic and for the demonstration of disadvantages of some texture characteristics, there are performed a comparisons of the different parameters evaluated on model surface profiles in the end of this work.
