The aim of the project was to develop diamond ground surfaces optimized for long-term noise reduction based on existing theoretical calculation models. The following development steps were provided:
- Development of a texture manufacturing process to improve the use and the properties of the concrete surface,
- Development of optimal and economical concrete compositions for the manufacturing process, taking into account the properties relating to the structural substance.
The intention is to produce diamond ground textures with good reproducibility of the noise reducing properties and skid resistance, with a level reduction of - 4 dB against the reference surface according to RLS-90.
