ASTM E2399 / E2399M - 15, Standard Test Method for
Maximum Media Density for Dead Load Analysis of Vegetative (Green) Roof Systems, ASTM International, West Conshohocken, PA, 2015, www.astm.org
1.1 This test method covers a procedure for determining
the maximum media density for purposes of estimating the maximum dead load for green roof assemblies.
The method also provides a measure of the moisture content, the air - filled porosity, and the water permeability measured at
the maximum media density.
1.3
The maximum media density and associated moisture content measured in this procedure applies to drained conditions near the saturation point.
