On behavior of limited life Geotextile materials for reinforcing embankment on soft ground

Constrain on availability of waste landfill sites and stinging environmental regulations are the major reasons stimulating interest in the use of Limited Life Materials in construction industry. The concept of limited life geotextiles seeks to emphasize a clear definable working life, where materials are designed so that progressive loss of their capability with time is matched with the improvement in the ground conditions with time. By clearly defining a working life of the geotextile base on the improvements in ground conditions overtime will reduce over-designing and construction. This paper mainly focus on the ability of biodegradable geotextiles to provide reinforcement to embankments constructed on soft ground where the foundation soil is too weak to support the embankment on it. It is well known that any degradable (decay) material has negative exponential function. Consequently nonlinear function which approximates decay phenomenon is engrossed with errors. The existing methods of investigating ti...
