Standard Test Method for Permeability of Synthetic Turf Sports Field Base Stone and Surface System by Non-confined Area Flood Test Method

Importancia y uso:

5.1 This test method can be used to determine in-place permeability of synthetic turf playing field systems, playing field systems with pad and or premolded drainage boards, playing field systems with premolded panel base systems, porous and non porous pavement systems in order to confirm compliance with design specifications and or evaluate existing as-built conditions. The simplicity of the test method, the quickness of the procedure, and the limited requirement for special tools and apparatus’ makes this ideal for performing a large quantity of tests over a large area such as a sports field.

5.2 Synthetic turf field systems tend to drain under several flow regimes. The first flow regime is surface flow where water travels across the surface from typically higher elevations to lower elevations. The second flow regime is flow through the turf surface and base system. The third flow regime is lateral flow, which has two parts. Lateral flow within the section of the turf surface and lateral flow within the pre-molded drainage board, porous pavement and or base stone system below the turf. These are depicted diagrammatically in Fig. 1.

5.3 This test method can provide owners, designers and turf system builders with a clear indication of actual in-field permeability flow rates with limited effect of lateral flow through base systems and no effect from head pressure.

5.4 This test method can be used to determine the effectiveness of treatments intended to reduce the effect of hydrophobicity which has been known to decrease the permeability of some synthetic turf infill materials and components.

5.5 The observable performance of the test method enables one to determine permeability by both a quantitative and qualitative measure.
