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 ...
Municipal solid waste management under COVID-19: challenges and recommendations
(2021)
Covid-19 is proving to be an unprecedented disaster for human health, social contacts and the economy worldwide. It is evident that SARS-CoV-2 may spread through municipal solid waste (MSW), if collected, bagged, handled, ...
Reducing the erodibility of sandy soils engineered by cyanobacteria inoculation: a laboratory investigation
(2023)
Windblown and water-induced erosion cause substantial soil losses worldwide, especially for drylands. Any sustainable management program that increases soil organic matter and improves the stability of the crustal layer ...
Reverse extrusion test for fine-grained soil characterisation: internal flow pattern with ANN-enhanced particle tracking
(2023)
The reverse extrusion test involves one-dimensionally (1D) compressing a fine-grained soil
sample contained in a cup container of cross-sectional area A. The force Fe applied by the
loading platen causes extrusion of the ...
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) ...
