An Innovative Hybrid Natural-Artificial Sports Turf Construction System: Plant Establishment and Playing Characteristics
No full textThird generation artificial turf pitches have long been the object of criticism due to their high abrasiveness, the high summer temperatures and their unpleasant rubber odour. On the other hand, natural turf pitches are not able to withstand the high play volumes currently associated with modern high-profile sports pitches and community sports pitches. An innovative hybrid natural-artificial sports pitch construction system was devised and tested at Pisa University. This system consists of a modified third generation artificial grass with organic infill on which natural grass is allowed to grow. In summer 2007 different natural turf establishment methods were tested on a trial area, while an 11000 m2 pilot pitch was constructed. Seeded perennial ryegrass monostand proved to be the best establishment method. The pilot pitch was tested for playing quality parameters after over 200 h of play: most of these fell within both the FIFA standard requirements for artificial turf and generally accepted playing quality parameters for natural turf
An Innovative Hybrid Natural-Artificial Sports Pitch Construction System
No full textThird-generation artificial-turf pitches are often criticized because of their high abrasiveness when athletes fall on the surface,the high temperatures recorded in summer periods,and their unpleasant rubber odour.On the other hand,natural-turf pitches are not able to withstand the high play volumes currently associated with modern high-profile and community sport spitches.Hybrid systems with a varying presence of artificial fibres and rein-forcements have long been tested and installed,without providing a definitive answer to the above-mentioned problems of natural turf.The aim of this study was to evaluate the playing characteristics and the wear resistance of a newly patented hybrid natural-artificial sports pitch construction system after rugby and foot-ball play for 2 months and 5 months.This hybrid system consists of a modified third-generation artificial grass with organic infill,on which natural grass was allowed to grow.A 11300m2experimental pitch was constructed in Pisa(Italy)in the summer of 2007 and tested during 2007-2008 following football and rugby union play for an average of 8-9h/week.The hybrid pitch showed a total absence of rubber odour,summer temperatures similar to those of natural-turf pitches,wear resistance superior to that of natural-turfpitches,abrasiveness similar to that of natural-turf pitches,and good infill particle size stability.Most playing-quality parameters fell within both the Fédération Internationale de Football Association(FIFA)Recom-mended2-Star Standard requirements for artificial turf and generally accepted playing-quality parameters for natural turf.Since then more pitches as described herein have been constructed and witnessed international match play,while FIFA has classified the system as a reinforced natural-grass pitch
