, stiffness) as well as their spatial configuration (e.g., matrix packing and fiber orientation, fiber distribution). However,a limited number of studies have been focused on the investigation of the behavior of polypropylene fiber reinforced sand using the direct shear apparatus. This paper presents the experimental results of direct shear tests carried out on sand samples reinforced with polypropylene fibers. Results of this study are presented and discussed regarding the effect of relative density, normal stress and fiber percentage on the shearbehavior of reinforced

captured by TLS based on Ground Control Points (GCPs) (terrain/dam details) were geometrically transformed, so that they received a consistent orientation.
Assuming that the measuring of laser beam reflection intensity allows for diagnosis of concrete construction conditions, [ 13 ] performed an analytical experiment exploring possibilities of using automated image recognition methods such as ISODATA (Iterative Self- Organizing Data Analysis Technique), [ 9 ]) used for unsupervised classification of multispectral satellite images [ 5 , 6 ]. This technique allows for
