The report first confirms the importance of micro- and macrotexture and explains its measuring devices, in particular a texture profile measuring device, developed by the Institute of Highways, Railways and Rock Engineering ISETH Zurich, which allows to quantify and to qualify macrotexture. A relation between surface texture values and the thickness of the waterfilm for hydroplaning conditions of a certain speed has been found after a great number of skid resistance measurements on five different pavement surfaces covered with waterfilms of 0.5 to 10 mm depth. The same results are used to show the limits for a classification of pavement surfaces based on standard measurement conditions (waterfilm 0.5 or 1.0 mm). /Author/
