| In this thesis different texture characterisation parameters have been described, analysed and tested on different pavement surfaces and profiler methods. Some of the parameters provide a detailed description of the shape of the asperities of the surface, which then can be treated statistically. Also a fractal approach is described which allows for a characterisation of the texture profile over the complete range of wavelengths. It is shown that the profile pre-processing has a significant influence on the results. Procedures are proposed which can be used in future standardization documents. All texture parameters have been determined on different types of asphalt and rock specimens in order to investigate possible correlations with the polishing level of the specimens and later on with friction measurements | |
