Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides.   Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies. Biological protection methods are alternatives that synergize better with ambitions for sustainable development.   The results indicate that drainage from upland sources is not properly surveyed ditches and trenches are not used often enough the rockfill covering could have been carried out more accurately grain size and thickness of the protective layer could both be downsized the relation principle between grain size and flow rate is hard to use large spaces are unnecessarily covered with gravel biological types of cover could in many cases work just as well a combination of rockfill with finer fractions, and grass or plants is an appealing alternative to the coarse gravel
