Permeability of geotextile-included railroad bed under repeated load
AbstractThis paper reports some experiments which were used to evaluate the change in permeability of a simulated railroad system with two variables—time and number of load applications. The change in permeability is due to clogging of soil fines in and around the geotextile. Test results have shown that the coefficient of permeability of the simulated railroad system decreases with the increase in time and decreases with the increase in the number of cycle of repeated load. Efforts were also made to unclog the geotextile by flushing water from the top, and the increase in permeability after flushing was evaluated. Reasons for the pumping action are discussed, and the sequence of the processes for clogging for the simulated railroad system is proposed.
