Stabilisierung ungebundener Tragschichten im Straßen- und Wegebau - eine Standortbestimmung

Stabilization of unbound granular layers in road constructions - defining a benchmark.

To improve the mechanical performance of unbound granular layers in road constructions, geosynthetics are used for the function of, amongst others, reinforcement by geogrids. As far as the geogrids are characterized by a suitable mechanical specification, the granular layers are reinforced even at very low deformations. For verbal and technical clarification the stabilization effect is understood as part of the reinforcement function. Tenders, bids, acceptances and contracts for products shall be worked out based on technical regulations and CE-marking documents for reinforcing products with slight additions, taking low strain and serviceability limit states into consideration. In opposite to layers mixed with binders, the water permeability is not influenced by this measure, and geogrid reinforced layers can be characterized by extraordinary ductility.
