Abstract
“Green” revolution is rapidly increasing in every construction site, especially between construction and societies’ needs. Furthermore, although durability of geosynthetics should be emphasized for long-term service period, durability controlled mechanism could be required to fulfil the short-term degradability purpose for green geosynthetics. “Green Geosynthetics” are made of eco-environmental biodegradable polymeric resins or natural materials and they must maintain their needed performance such as durability, design strength, hydraulic property, etc., during service period in the application field. Then, after service period they should not be degraded in harmful state in the soil structures. The important concept of green geosynthetics is focused on their degradable behaviours of used resins and needed performance for engineering qualification with technical data of designing. In this study, technical availability of green geosynthetics was introduced and reviewed to be related to the quantitative analysis of biodegradability of green geosynthetics by conceptual consideration through its evaluation. Still now, there is no international test method to evaluate the biodegradability of green geosynthetics performance and only the geosynthetics performance test methods of ISO and ASTM International are applied for this purpose. However, it is not reasonable for green geosynthetics to adopt these test methods directly and new test methods should be introduced for green geosynthetics performance testing. In this study, the regulation of evaluation method of biodegradability for green geosynthetics between index and field tests is proposed by connection key factor to confirm the biodegradable behaviors for green geosynthetics.
