Artificial grass structure provided with a granular infill comprising additives

The invention relates to an artificial turf suitable for sports fields consisting at least of a substrate to which first artificial grass fibres are attached and of a granular infill, which is provided between said first artificial glass fibres and which is made of a recyclable synthetic material. The invention furthermore relates to a granular infill for use in an artificial turf suitable for sports fields. The use of an infill in artificial grass sports fields has a number of drawbacks. Not only is the construction of such a artificial grass sports field more labour-intensive than the construction of a natural grass sports field, but an artificial grass sports field provided with an infill requires subsequent maintenance as well. The initially uniform distribution of the granular infill can be disturbed by intensive usage. Furthermore it has become apparent that the weather influences affect the properties of the infill with the passage of time, which has a negative effect on the quality of the infill and thus on the playing characteristics of the artificial grass sports field. The object of the invention is to provide an artificial glass sports fields that does not exhibit the above drawbacks. According to the invention, the artificial turf is characterized in that one or more additives have been added to the granular synthetic infill for improving the playing characteristics of the artificial turf.
