The settlement occurring during landfill construction often causes a damage of drainage system. Clogging can reduce the hydraulic conductivity of the Leachate Collection and Drainage System, which results in the increase of leachate level within the landfill. Consequently, the insulation ability of leachate will be decreased. The main purpose of this project is to estimate a newly designed reinforced drainage geotextile (RDG) combining non-woven fabrics with geogrid for minimizing the destruction of drainage layer as well as evaluating RDG's application in the leachate collection and drainage system. Thus, the project observed the permittivity changes of RDG, and evaluated the drainage ability using RDG in the leachate collection and drainage system.
