For centuries, earthen materials have regained popularity because of the high carbon emissions caused by construction sector. Although earth-based possess superior properties, such as recyclability, easy accessibility, affordability, and thermal conductivity, they are not without drawbacks. They are, for instance, relatively weak sensitive to water, their physical chemical properties can vary considerably depending on source from which obtained. Stabilisation is often used overcome these In this study, natural were stabilised with biopolymers organic origin, alginate, Arabic gum, xanthan locust bean preserve properties. To produce samples, earth material in road sub-base layer was mixed kaolin clay silica sand, mixtures prepared substituting biopolymer at a ratio 0.1%. After determining fresh unit volume weights, spreading diameters (flow table test), penetration depths (fall cone air content mixtures, flexural compressive strengths cured specimens measured. addition, scanning electron microscopy (SEM) X-ray diffraction (XRD) analyses performed determine microstructural characteristics. According 28-day strength results, mix gum found be almost twice strong other mixes. It has been concluded that biopolymer-stabilised fill buildings where required, or paving low-traffic roads.
