Bonded dynamic layer underneath sports ground surfacings

摘要

To increase the compliance and improve the functional suitability from both technical and sporting aspects, the bonded dynamic layer comprising firm and flexible aggregates - bonded by an elastic binder - is formed in particular underneath sports ground surfacings composed of synthetic materials. The compliance can be adjusted and the layer made water-permeable or water-impermeable by using different mixing ratios. Use as an in-situ layer or by laying prefabricated sheets or webs. All known and conventional sports ground surfacings can be covered in this way.
