Geotechnical Properties of Rubber-Modified Soils
Summary
In recent years, the incorporation of rubber waste—ranging from crumb rubber and powder to tyre-derived aggregates—into natural soils has emerged as a sustainable strategy to enhance or tailor key geotechnical properties. By blending rubber particles with clays or silts, researchers have aimed to mitigate soil expansivity, reduce density, increase ductility and energy absorption, and modulate strength and stiffness parameters. The elastic nature of rubber imparts improved deformation capacity and energy dissipation, often transforming soils from brittle to more ductile materials. Furthermore, the hydrophobic character of rubber phases alters consolidation behaviour and swelling-shrinkage cycles, while the reduction in overall unit weight can prove advantageous for light-weight fill applications and land remediation. Beyond performance gains, the practice offers environmental benefits through the diversion of end-of-life tyres from landfill, supporting circular economy goals in civil and geotechnical engineering.

Geotechnical Properties of Rubber-Modified Soils publication trend
The graph below shows the total number of articles in geotechnical properties of rubber-modified soils across all publications each year (not limited to Nature Index journals).
Technical terms
Unconfined compressive strength (UCS): The maximum axial stress a soil specimen can sustain without lateral support.
Modulus of elasticity: A measure of soil stiffness, defined as the ratio of stress to elastic strain under load.
Consolidation: The process by which a soil volume decreases under sustained load due to pore-water expulsion.
Swelling index (Cs): The slope of the void ratio versus log effective stress curve during unload-reload in consolidation tests.
Compression index (Cc): The slope of the virgin compression line in an e–log p′ plot, indicating primary consolidation compressibility.
Void ratio (e): The ratio of the volume of voids to the volume of solid particles in a soil.
Proctor compaction test: A standard laboratory method to determine the maximum dry density and optimum moisture content of a soil.
Angle of internal friction (φ): A parameter describing the shear resistance of soil due to interparticle friction.
Cohesion (c): The component of shear strength arising from interparticle bonding, independent of normal stress.
Tyre-derived aggregate (TDA): Recycled rubber chips or particles processed from waste tyres, used as soil amendments.
