Definitions

  • the invention relates to a substructure construction for an artificial grass field consisting of a sand bed with provided thereon a layer which contributes towards the damping, said layer besides lava grains comprises rubber particles.
  • the invention furthermore relates to an artificial grass field having such a substructure construction.
  • Such a substructure construction is known from the German "Offenlegungsschrift" 3,535,432, said substructure construction being built up of lava grains having a grain size of 0 - 16 mm and fibres or a product obtained by cutting rubber, said product hereinafter being indicated as rubber particles having a length of 20 - 50 mm and a thickness of 2 - 5 mm.
  • no information is provided as to the ratio between the quantity by weight of the rubber particles and the quantity by weight of the lava grains. It has now been found that by using different rubber particles in a certain weight ratio with respect to the lava grains a better damping can be achieved.
  • Said construction is costly because it is built up from a substructure construction comprising at least three different layers and, moreover, the artificial grass field thus obtained does not have the desired damping.
  • An improved substructure construction for an artificial grass field which can be used especially for soccer, because a better damping is obtained, is mentioned in the European patent specification 0,136,747.
  • the substructure construction described therein is composed of unbroken sand which is mixed with at least 1 per cent by weight of a fibrous material, for which purpose polypropylene fibres, Nylon fibres or glass fibres were mentioned.
  • the substructure construction was based on a mixture of sand and shreds or fibres of an elastomeric material, the shreds or fibres constituting 10 - 50 per cent of the mixture.
  • the shreds or fibres are made of rubber, with an elongated shape as is obtained by cutting car tyres.
  • a substructure construction consisting of a stable lava skeleton in which the lava grains have been replaced by rubber grains.
  • the lava thus provides the stability and the rubber provides the damping.
  • the damping capacity will decrease more than is desirable after repetitive loads, although this can be slightly compensated for by a more optimal distribution of the particle size.
  • the rubber grains preferably have a particle size of 2 - 15 mm, and the lava grains a particle size of 2 - 16 mm. That is the reason why in the following examples there are described substructure constructions for artificial grass fields containing more than 8 per cent by weight of rubber grains.
  • a mixture of lava grains having a particle size between 11 and 16 mm was mixed with rubber grains having a particle size of 7 - 15 mm, in a ratio such that the mixture contained 91 per cent by weight of lava and 9 per cent by weight of rubber.
  • This mixture a substructure construction was produced for an artificial grass field for playing hockey. From further measurements it became apparent that this field had a permanent damping capacity of 31%.
  • the mixtures of lava and rubber had a specific weight of 1.2 - 1.3, calculated on the basis of the dry material.
  • a substructure construction was designed consisting of 86 per cent by weight of lava grains having a particle size of 11 - 16 mm and 14 per cent by weight of rubber grains having a particle size of 7 - 15 mm. With such a substructure construction a permanent damping capacity of 38% could be obtained, so that this field could be used successfully as a soccer field and as a hockey field.
  • a multifunctional artificial grass field was provided with a substructure construction consisting of 86 per cent by weight of lava grains having a grain size of 2 - 11 mm and 14 per cent by weight of rubber grains having a particle size of 2 - 15 mm.
  • This field had a permanent damping capacity of 44%, and could be used successfully for playing hockey, soccer and korfball.
