Noise protection wall, has supporting stone possessing elevation surface made of natural stones, and sound absorption layer connecting elevation surface with supporting stone over adhesive bond

摘要

The wall (1) has a supporting stone (2) made of heavy concrete, where the supporting stone possesses an elevation surface (4) made of natural stones (5). A sound absorption layer (3) made from lightweight concrete connects the elevation surface with the supporting stone over an adhesive bond. The natural stones are arranged in a bidirectional flow layer before the sound absorption layer that is designed as a lightweight aggregate concrete shell. An independent claim is also included for a method for manufacturing of a noise protection wall.
