Gravel turf consists of a gravel area, ideally composed of square-edged grain and planted with herbs and grasses. It is more ecological than other construction methods and has numerous additional advantages. Gravel turfs have a high loading capacity and can be used multi-functionally. The unsealed area allows rain water to permeate. Further positive aspects are aesthetics and low costs. Nevertheless there are also uncertainties and problems connected with gravel turfs, requiring more research in the future. In the theoretical part of this diploma thesis, some of these problem areas are investigated and possible solutions are discussed. The practical part of the paper contains the analysis of a negative example of a gravel turf car-park situated near the Schwackhöfer-Haus on the Campus of the University of Natural Resources and Applied Life Sciences in Vienna. For the original surface at this location, round grain was used, which was then replaced by square-edged grain during reconstruction. From November 2005 to July 2006 tests for the identification of the loading capacity, of the grain size distribution and of the water permeability were conducted. After a study of the vegetation and the interpretation of the test results, it can be concluded that the reconstruction was necessary and successful. In addition to the investigation near the Schwackhöfer-Haus, the vegetation of the test areas "Treppelweg" and the car-park "Segelhafen" was analysed. In the course of this analysis, research concerning the coverage of the surface and the dominance of certain plants was carried out, in order to find out how vegetation has developed and changed since previous research projects HAAS/SCHILD (2001/2002) and LÄNGERT (2003).
