Abstract/Contents: | "Two commonly used systems for putting green construction allow for either a two-layered profile (i.e. a rootzone layer over a drainage layer) or a three-layered profile, which includes an intermediate layer between the rootzone and drainage layers. The main purpose of the intermediate layer is to prevent finer particles from the rootzone migrating downwards and blocking the pore space within the drainage layer when relatively coarse gravels are used. The objective of the current study was to assess rates of particle migration, in the absence of an intermediate layer, from the rootzone into the drainage layer in relation to particle size differences between the two layers. Particle migration was examined after the application of 3000 mm of water over a period of thirty weeks. Plaster of Paris and epoxy resin containing a fluorescent dye were used to stabilise the profiles so that they could be sectioned and photographed under ultra-violet light. Particle migration was minimal, except when a very dry and comparatively fine rootzone based on a medium sand (89 % < 0.5 mm) was placed over coarse gravel (D15 ā„ 4.4 mm). Even for these profiles, no more than 34% of the pore space within the gravel immediately below the rootzone/gravel interface was blocked by rootzone material. At depths of more than 25 mm below the interface, no more than 10% blockage of the pore space was recorded. On the basis of the results, it is proposed that in two layered profiles, criteria for the bridging factor between the rootzone layer and the drainage layer should be relaxed, with the D15 size value for the gravel being no more than eight times the D85 value for the rootzone." |
