The concept of healing and self-healing in construction materials is a novel and important topic for understanding their behavior under different environments, where they exhibit a recovery property without or with the limited involvement of any external agencies. In this study, biopolymer Xanthan Gum was used to promote soil self-healing properties. The goal of this study is to understand and present the overview of the self-healing mechanism of the biopolymer amended soil and its potential within green geotechnical and construction engineering. This study presents the results from the preliminary experiments inspecting the potential for self-healing through one-dimensional consolidation tests on biopolymer-amended soils using an oedometer where the sample specimens were tested under different loading and unloading conditions at different temperatures. The experiment demonstrates the potential for the Xanthan Gum in soils to persist and heal damage by itself. Furthermore, this study shows a significant increase in the compressibility index and self-healing properties of soils with the presence of biopolymers than the plain soils. The environmentally friendly characteristics of the biopolymer and the promising results of this study make biopolymer a good option for rapid temporary construction or long-standing construction sustainable in nature.
