Geotextiles drainage function

Impermeable soil base 8.4 Geotextile drainage function. [Pg.264]

Separation filtration (a) and drainage functions (b) of geotextiles in road construction. [Pg.321]

The approach of multilayering of coarse and fine fibres has also been applied for enhanced drainage functionality. One development is a three-layer non-woven geotextile which is claimed to give a better performance than drainage geocomposites with a geonet core. The three-layer non-woven... [Pg.340]

The potential development of electrokinetic geotextUes offers an opportunity to increase the redevelopment of derelict land as a means of reducing the pressure for construction within the natural environment. This electrically conductive material enhances the filtration and drainage functionalities by electro-osmosis and ion migration. Various types of conductive component can be incorporated in the geotextile structure to achieve this effect, but the possible use of activated carbon fibre or similar additives with pollution sorptive surface properties can aid land recovery of poUuted areas. [Pg.341]

With the needle-punched nonwoven geotextiles, the water can move in both the vertical and horizontal directions. The nonwoven geotextiles can provide a drainage function by transmitting liquid within the plane of their structure. This means the flow is predominant in the lateral direction, and this is important in assessing the in-plane hydraulic properties (Kopitar, Skenderi, Rukavina, 2014). [Pg.347]

Geotextiles and other geosynthetics installed to transmit hquid in their plane provide a drainage function. [Pg.151]

Drainage can be defined as follows a sod—geotextile system in equilibrium that allows for adequate liquid flow with limited soil loss in the plane of flie geosynthetic over a lifetime of service compatible with the apphcation under consideration (Koerner, 2005). Therefore, drainage function refers to the flow of water or other fluids along the geosynthetic plane (transmissivity or in-plane permeability). [Pg.151]

Fabrics perform one or more function in each installation generally there is one primary function. The five basic primary functions have been identified as separation, stabili2ation, reinforcement, filtration, and drainage. When the geotextile is impregnated with an impermeable material such as an asphaltic... [Pg.258]

In separation, the primary function of the geotextile is to prevent intrusion of one material into another in order to prevent contamination of either material by the other. In the case of an aggregate being placed over a firm foundation soil, the purpose is to maintain the drainage integrity of the aggregate wall application is similar. In landfill application, the purpose is to prevent intrusion of waste material into the leachette collector system. [Pg.259]
