Improved geotechnical behavior of an expansive soil amended with tire-derived aggregates having different gradations
(2020)
This experimental laboratory study examines the potential use of tire-derived aggregate (TDA) products as an additive to alleviate the inferior geotechnical properties of a subgrade deposit of clay soil with high ...
Effect of chitin, chitosan and NaCMC biopolymers on the consistency limits of organic silt
(2024)
With global concerns on carbon emissions, there is increased need for various eco-friendly alternatives to conventional
(cement and lime) additives used in ground improvement applications. This paper investigates the ...
Cyclic swell–shrink behaviour of an expansive soil treated with a sulfonated oil
(2022)
The effects of a sulfonated oil (SO) stabiliser on the swell–shrink properties of an expansive soil were investigated through cyclic wetting–drying tests. The cyclic wetting–drying action led to the reconstruction of the ...
Reappraisal of soil extrusion for geomechanical characterisation
(2019)
Reverse extrusion has been promoted over the past four decades for remoulded undrained shear strength (s u) measurement and consistency-limit determinations. The technique employs a uniaxial-compression test machine to set ...
Geomechanical behaviour of uncemented expanded polystyrene (EPS) beads?clayey soil mixtures as lightweight fill
(2021)
Lightweight fill can be advantageous in embankment construction for the purposes ofreducing the (i) bearing pressures on the underlying soil foundation, (ii) destabilizing moments forconstructed earthen slopes, and (iii) ...
Environmental geotechnics: challenges and opportunities in the post-COVID-19 world
(2021)
The outbreak of the coronavirus disease 2019 (Covid-19) pandemic not only has created a health crisis across the world but is also expected to impact negatively the global economy and societies at a scale that is maybe ...
Stabilization of a highly expansive soil using waste-tire-derived aggregates and lime treatment
(2022)
This study investigates the combined efficacy of waste-tire-derived aggregate (TDA) materials and hydrated lime on the compactability, compressive strength and swelling potential of a highly expansive soil from South ...
Improving internal erosion resistance of silty sand using additives
(2020)
Seepage-induced erosion, leading to piping, is one of the most common causes of failure for earth dykes, levees and dams. Various soil improvement (mixing) technologies can be employed to improve the internal erosion ...
