SELECTION OF GEOTEXTILE FILTERS WRAPPED AROUND PIPES IN PAVEMENT EDGE DRAINS

Geotextile filters are rapidly replacing graded granular filters as the standard practice in geotechnical design. This paper describes a laboratory study on filtration behaviour of three different kinds of geotextile, in order to select the most suitable fabric for a particular field application of pavement edge drains. Based on long- term performance studies of the geotextile filters wrapped around drain pipes, retention and permeability criteria for selection of the geotextile under a compacted backfill have been recommended. Regarding the clogging resistance criterion, it has been concluded that instead of choosing a geotextile based on its indicative pore size, it would be advisable to conduct a gradient ratio test at equilibrium flow conditions for studying the clogging resistance of geotextiles.
