Expansive soils swell when they absorb water and shrink by losing water. This process causes significant volume changes in highly expansive clay soils. Clay soil foundations have caused problems for various civil engineering projects, including pavements, railroads, embankments, worldwide. Besides, the accumulation of huge amounts waste glass is responsible several environmental issues. Although idea using pavement application not new, adoption treatment as subgrade has been rarely studied....
Abstract Low plasticity clays are found in abundance worldwide, exerting undue stresses on civil structures, road pavements and railway infrastructure, owing to the periodic settlement caused by their low bearing capacity slight swelling potential. They often encountered as natural soil when constructing subgrade have potential compromise integrity of entire pavement system unless improved appropriately. Furthermore, accumulation vast quantities non-biodegradable glass waste is identified a...
Brown coal fly ash (BCFA) is a lower-quality type of produced through brown combustion, and its disposal in landfills raises environmental concerns. This study, for the first time, evaluates feasibility using BCFA stabilising expansive clay subgrade pavement construction. Various engineering tests were conducted, including unconfined compressive strength (UCS), repeated load triaxial (RLT), soaked California bearing ratio (CBR), direct shear, shrink-swell tests. The results indicated that...
The construction sector has undergone significant reforms towards increased sustainability in recent decades. Therefore, there been a great interest developing alternative binders for stabilising expansive clay subgrades and improving their mechanical properties while mitigating swelling shrinking behaviour. One such binder is vinyl acetate-ethylene (VAE) polymers. However, are only few studies on utilising polymers, especially VAE stabilisation. Specifically, lack of research using...
In recent years, the construction industry has shifted toward sustainability, replacing traditional binders with eco-friendly alternatives. One such alternative is vinyl acetate-ethylene (VAE) polymer, known for its hydrophobic properties and used in various materials. This study explores potential of VAE polymer to stabilize expansive clay as road subgrade material. was introduced into low-plasticity varying percentages (1%, 1.5%, 2% by dry weight clay), mixtures underwent a series...
