EnglishThis paper presents the results of an experimental study that had the goal of understanding the effects of treatment with polyethylene glycol (PEG)/nanolime mixtures on collapsible soil behaviour. In a previous study, the use of pure PEG offered a good improvement in the stability of collapsible soil, but the stabilisation effect only lasted for a limited time. To investigate the stabilisation potential of PEG/nanolime systems for collapsible sand, different mixtures were prepared at increasing nanolime weight ratios. The suitability of the stabilised soil was examined on the basis of collapsibility, oedometer, shear, and water vapour permeability tests, and through optical microscopy and scanning electron microscopy observations. The stabilisation effects were analysed by comparing the mechanical behaviour of the sand before and after each treatment. The results showed that even though using various mixtures had different effects on the behaviour of collapsible soils, the treatment produced a significant change in the geotechnical behaviours of the sand in relation to the collapse potential, permeability, compressibility, and shear strength.

| Abstract: | This paper presents the results of an experimental study that had the goal of understanding the effects of treatment with polyethylene glycol (PEG)/nanolime mixtures on collapsible soil behaviour. In a previous study, the use of pure PEG offered a good improvement in the stability of collapsible soil, but the stabilisation effect only lasted for a limited time. To investigate the stabilisation potential of PEG/nanolime systems for collapsible sand, different mixtures were prepared at increasing nanolime weight ratios. The suitability of the stabilised soil was examined on the basis of collapsibility, oedometer, shear, and water vapour permeability tests, and through optical microscopy and scanning electron microscopy observations. The stabilisation effects were analysed by comparing the mechanical behaviour of the sand before and after each treatment. The results showed that even though using various mixtures had different effects on the behaviour of collapsible soils, the treatment produced a significant change in the geotechnical behaviours of the sand in relation to the collapse potential, permeability, compressibility, and shear strength. |
