A SPORTS FIELD, IN PARTICULAR A TENNIS COURT, A METHOD OF CONSTRUCTING A TENNIS COURT AND TOP LAYER COMPOSITION FOR A COURT

摘要

The present invention relates to top layer composition for a playing court, in particular an outside tennis court, a method for constructing a tennis court and a sports field, in particular a tennis court, with a surface layer made of the top layer composition. Soft courts have many disadvantages as e.g. high construction and maintenance costs, the need for frequent rolling, smoothing and replenishing of the surface materials for keeping the surface in a playable condition and so on. Many of these problems can be alleviated considerably by sprinkling the surface with water. However, during periods of winds or play, sprinkling is impractical. It is therefore the purpose of the invention to provide a playing court and a surface for the playing court that reduces the aforementioned disadvantages. Such purposes are accomplished by a to player composition for a playing court, in particular an outside tennis court, the top layer composition comprising substantially a mixture of crushed brick and/or quartz sand and/or volcanic ash and a microporous zeolite mineral,whereinthemicroporous zeolite mineral is present in the amount of % to 100 % of the total mass of the top layer composition, wherein the grain size of the crushed brick and/or quartz sand and/or volcanic ash is smaller than 3.15 mm, and wherein the grain size of the microporous zeolite mineral is between 0.03 mm 2 and 2.2 mm.
