Abstract
Eco-friendly environmental concept in geosynthetics application fileds, green revolution is rapidly increasing in every construction sites e.g., green structure, green installation, green industry etc. especially on the eco-environmental point of view. Biodegradable geosynthetics as a green material could be made from ecoenvironmental polymeric resins and they must maintain their needed performance during service period in the real field application. The basic technology trend and concept of biodegradable geosynthetics is reflected to ecoenvironmental growth in civil engineering fields. The important concept of biodegradable geosynthetics is focused on their degradable behaviors of used resins and needed performance for engineering qualification with evaluated technical data. Therefore, it is very important to select what kind of raw resin, additives and plasticizer to control the biodegradability. In this study, to consider this, environmental availability of biodegradable geosynthetics by PLA (poly lactic acid) was introduced and reviewed to be related to the quantitative analysis of degradability as long as biodegradable geosynthetics are installed in soil structure. And technical availability of biodegradable geosynthetics was introduced as green geosynthetics and reviewed to be related to analysis of degradability by conceptual consideration. The important concept of biodegradable geosynthetics is focused on their degradable behaviors of used resins and needed performance for engineering qualification with technical data of designing. Through the overall review of degradability of biodegradable geosynthetics, it is seen that biodegradable mechanism could be controlled theoretically and more restricted design technology must be adopted in the quality control and assurance of manufacturing procedure in the installation field. Finally, to evaluate the degradable performance of biodegradable geosynthetics, new test concept and the needed evaluation items should be selected by considering influence parameters on the long-term performance under real field installation conditions. PLA based geosynthetics will be used in the special and alternative application fields if biodegradable mechanism could be controlled.
