“…The expansive soil is one of the most problematic when it comes to building on because it has a lot of limitations, such as high compressibility, moisture content, volumetric changes, and low shear strength [1,[3][4][5][6]]. Yet it has some undesirable geotechnical properties that can cause unbuilt construction areas without stabilisation, especially road construction that requires strong and durable subgrade [6,7], Settlement results from swell-shrink cycles caused by seasonal moisture uctuations in expansive soil subgrade. Current solutions include partial removal and replacement of such subgrade soil or stabilisation as remedies [8][9][10][11][12][13].…”

Soil stabilization is the optimal approach that can improve various soil properties, including permeability, compressibility, strength, and durability. It is widely known that chemical stabilization can improve the mechanical characteristics of problematic soils. This work examined sodium alginate (SA) as a sustainable bentonite clay stabiliser to improve a high-plasticity clay. We soaked sodium alginate at different concentrations (0%, 0.5%, 1%, 1.5%, 2%, and 3%) to stabilise the bentonite clay of the compacted soil samples, utilising techniques such as standard proctor and unconfined compressive strength (UCS), scanning electron microscopy (SEM) coupled with energy-dispersive spectroscopy (EDS), and X-ray diffraction (XRD). Adding sodium alginate in different amounts (0.5%, 1%, 1.5%, and 2%) lowered the optimum moisture content (OMC) and raised the maximum dry density (MDD). Following 0, 14, and 28 days of curing, the UCS of stabilized samples were evaluated. It was found that adding 2% sodium alginate to bentonite clay raised both the maximum dry density and the optimum moisture content. The soil stabilized using the soaking technique displayed a higher 14-day UCS at the ideal sodium alginate content of 2% compared to the untreated soil. The microstructural investigation showed that the increase in strength was due to sodium aluminosilicate hydrate, a new cementitious material that filled in the pores and made the bonds between particles stronger. This research's conclusions will support bentonite clay's stability through the use of environmentally acceptable sodium alginate in subgrade applications.

“…The usage of 30% marble dust was cost-effective to provide adequate strength to the flexible pavement subgrade (Ditta et al). Jain and Jha (2020) studied the effect of the strength and rigidity of marble dust on finegrained soils and coarse-grained soils. For both soaking and unsoaked conditions, the CBR measurement was utilized to evaluate the subgrade rigidity and stiffness of soils modified with varying percentages of marble dust for better understand how it interacts with soil, physicochemical investigations such as mixtures pH and electrical conductivity have been performed by (Jain and Jha, 2020).…”

In geotechnical engineering, the process of changing the characteristics of weak or undesirable soils using waste materials has gained importance. Waste materials frequently involve waste and by-product minerals, such as marble powder, which were unethically obtained in Iraq and had harmful environmental repercussions. The aim of this study is to determine how marble powder affects the geotechnical features, including consistency limits, density, shear strength parameters and swelling characteristics of clayey soils in Erbil city. Different percentages of marble powder (6%, 12%, 18%, 24%, 30%, and 36%) were used to treat the expansive soil. The outcomes indicated that marble powder could enhance the geotechnical properties. It is advised to add 18% percentage of marble powder to improve the soil as an optimized amount.

“…This is due to the fact that large amounts of sludge, constituted by fine mineral materials, are unavoidably produced during aggregate production, and it has been observed that their stockpiling and/or disposal is one of the major problems faced by the aggregate industry [ 36 ]. Several attempts have been made to reuse MS, especially in pavement subbase and base layers [ 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ], and in the pavement foundations in tunnels [ 35 , 45 , 46 , 47 , 48 ], thereby confirming the possibility to turn this waste material into a valuable resource.…”

A Sustainable Cold-Recycled Solution for the Surface Finishing of Unpaved Rural Roads

This paper presents the results of an experimental investigation which was carried out with the purpose of assessing the performance-related properties of an emulsion-based cold-recycled mixture to be employed as a sustainable solution for the surface finishing of unpaved rural roads. This mixture contained significant quantities of recycled components (reclaimed asphalt and mineral sludge), and its composition was fine-tuned by following an innovative mix design procedure. Properties of these mixtures were studied by means of laboratory tests which considered key parameters, such as flowability, indirect tensile stiffness modulus, indirect tensile strength, moisture susceptibility and resistance to permanent deformation. It was found that, by means of the proposed mix design procedure, optimal dosages of the recycled components can be identified, thereby ensuring the achievement of the desired properties in terms of high workability and adequate stiffness and strength.
