Abstract: Reinforcement element (10) for increasing the strength of self-solidifying pasty materials which is made of bendable filaments, that comprises a central portion (12) from which at least in three directions respective arms (11) extend out and each of the arms (11) have at least two spaced filaments (13), and the arms (11) have outer ends constituted by respective loops (14) made by the bending of the filament (13) of which the associated arm (11) is made, and in each loop (14) the distance between the filaments (13) is between the twice and twenty fifth times of the size of the filament (13), and the arms (11) are arranged in such a way that in any half space separated by any plane lead through the central portion (12) at least one of the arms (11) is arranged.

Abstract: Concrete based reinforced road structure covered by asphalt that comprises a basic layer (1) made of concrete with a substantially horizontal upper surface and placed directly or through a subconstruction on the ground and at least one mould cover layer (2) thereon made of asphalt, and support elements (3) positioned between the basic layer (1) and the cover layer (2), wherein the support elements (3) are inserted in a predetermined depth in the basic layer (1) prior to the setting thereof so that they are partially projecting out of the basic layer (1) in normal direction to the upper surface, and the projecting portion provides protection to the cover layer (2) against being displaced relative to the basic layer (1) under loads to which the road is exposed, and the support elements (3) are flat stripes with walls being substantially normal to the surface of the basic layer (1) and comprising subsequent sections with differing directions to form respective meandering lines.

Abstract: A downhill sliding course of sliding track for sliding objects and persons down a slope or a hill includes covering or cladding elements for covering the surface of the slope and a water source to moisten the elements with water. The sliding elements include pools located one below the other, wherein the pools are forming water filled micro-terraces (10). The micro-terraces (10) are formed by a sheet covering the slope in a water-tight manner and flexible ribs (2) are emerging from the sheet, furthermore each pool is bordered by the covering sheet (5) and the rib (2) and is closed by a flexible transverse sectioning rib joined to the covering sheet (5) and the flexible rib (2). With suitable accessories activities similar to skiing, sleighing and surfing can be performed on the sliding course. Accordingly, the invention includes also accessories that can be used to perform these activities. The invention provides individual appliances to implement the sliding course.
