| 摘要 |
A grass surface (1) on a soccer pitch has a top surface (2) under which is an upper layer (3) formed from a growing material having silica sand, elastomeric polyurethane fibres, rigid polypropylene fibres and soil to produce a resilient, reduced-hardness surface with good ball-rebound and traction performance. There is then a lower rootzone (4) of a sand/soil blend, below which is a layer of graded gravel with drainage channels (6).
