“…The swell potential (S) was defined as (∆h/hi)×100, where hi represents the initial thickness of the sample and ∆h is the increase in thickness at a specific time. Swell pressure was determined as the total vertical pressure necessary to achieve zero axial strain, per the swell under load method [4].…”

“…The damages caused by these types of soils are estimated to be billions of dollars annually [3]. Therefore, in cases where it is not possible to avoid the construction of superstructures on these types of soils by changing the route of the road, measures should be taken to reduce the swelling of the soil, and the construction of superstructures on these soils without stabilization should be avoided [4,5]. Usually, fine-grained soils bear a significant load when subjected to moisture less than the optimal level, but as the moisture level increases, their resistance decreases, and more deformations occur in the soil.…”

“…Other researchers, such as Zumrawi and Mohammed (2019), have also scrutinized the effect of polyvinyl and acetate [22]. In a study conducted by Mousavi et al (2021) [4], the influence of CBR Plus and RPP on the mechanical properties of swelling soil was explored. The findings indicated that these materials could decrease the plasticity index and swelling potential of swelling soils [4].…”

The findings indicated that these materials could decrease the plasticity index and swelling potential of swelling soils [4]. In general, considering the relatively low energy requirements for producing these materials, substituting a part of traditional stabilizers with environmentally friendly materials can be even more economical.…”

The findings revealed that the addition of nanoalginate and lime had distinct effects on various soil properties. Specifically, the liquid limit (LL) and plastic limit (PL) decreased when sodium nanoalginate and lime were added, while the plasticity index (PI) and shrinkage limit (SL) increased. Furthermore, the soil classification was altered when sodium alginate and lime were introduced to the control soil. Regarding the standard Proctor test, it was observed that adding sodium nanoalginate increased the maximum dry density and reduced the optimal moisture content, whereas lime had the opposite effect by decreasing the maximum dry density and increasing the optimal moisture content. The free swelling and swelling pressure tests indicated that the incorporation of sodium nanoalginate and lime reduced both free swelling and swelling pressure. The most significant reduction was observed in the sample containing 7% sodium nanoalginate and 5% lime. Additionally, the study highlighted the influence of processing time, showing that an increase in the curing time led to a decrease in free swelling and swelling pressure in samples mixed with 3% sodium nanoalginate and lime. The XRD test showed that adding sodium nanoalginate reduced primary minerals, forming SAH, while lime reduced quartz and calcite, creating CSH. Overall, the results suggest that sodium nanoalginate can be a more environmentally friendly alternative to lime for soil stabilization projects.

“…Their interaction with soil particles leads to changes in water attraction. Consequently, water is expelled during the compaction process which results in increased bearing capacity and other mechanical properties of the treated soil [7]. In the case of chemical treatment, it is also important to verify if the soil can be treated with chosen agents.…”

One of the methods of strengthening the subgrade under the road pavement construction is its stabilization with a hydraulic binder. The technology of stabilization with binders is well known in the road engineering, however, it is still beneficial in terms of economical and organisational aspects while considering methods for improvement of the load-bearing capacity of the subsoil. The advantages of this technology are, among others, the possibility of using materials both from recycling and local materials, resulting in the possibility of waste production limitation by the use of weak material (soil) in place. The article presents a case study and the results of research obtained during the process of optimizing the thickness stabilized with a hydraulic binder. Comparative tests were carried out to reveal that non-chemical soil enhancement with the use of aggregate is as important as chemical one with the binder in terms of the quality of the final subgrade for road construction. The results were afterwards confirmed in field with use of heavy machines and full-scale soil stabilisation, leading to economic and environmental benefits.
