ASTM F2898-11 (R2019) PDF Download

A common test procedure used to measure the permeability of synthetic turf sports field base stones and surface systems is ASTM F2898-11 (R2019). It is intended to assess current conditions and certify conformity with design parameters. The test method is appropriate for carrying out several tests over a large area, such as a sports field, because it is rapid, easy to use, and requires few specialized tools and equipment.

In synthetic turf field systems, the test method takes into account several flow regimes, such as surface flow, flow through the turf surface and base system, and lateral flow inside the turf surface and pre-molded drainage board or base stone system. With little or no influence from head pressure and a clear depiction of the real in-field permeability flow rates, it is effective.

This test method can be used to analyze the efficacy of treatments intended to lessen the influence of hydrophobicity on the permeability of synthetic turf infill materials and components, in addition to determining permeability.

The test method enables evaluation of permeability performance on a quantitative and qualitative level, offering useful data to owners, designers, and manufacturers of synthetic turf systems.

Additionally, the standard lists particular constraints and concerns. It is suited to porous or non-porous pavement systems, premolded panel base systems, and synthetic turf playing field systems with pad or premolded drainage boards. It is appropriate for finished surfaces with cross-slope gradients of less than 2.0% or for compacted and graded stone, as well as for systems with high permeability that lessen the impact of cross-slope. It is not relevant in locations where surface flow transports water to drainage systems or right away following heavy rainfall events that can affect downstream drainage capacity.
