The performance of the supervised machine learning models are assessed using statistical parameters. The SVM model results in the best and highest performance algorithm, which suggests that this algorithm is more robust in comparison with others in rockfill material shear strength prediction. On the other hand, in the ninth paper, [PERSON] et al. [6] study the performance of four machine learning algorithms (artificial neural networks, support vector machines, random forest, and multiple regression) to predict the unconfined compressive strength and the tensile strength of soil-binder-water mixtures reinforced with short fibres. Exploring global sensitivity analysis ensured a deeper understanding around the proposed algorithms. The authors concluded that the proposed models were able to catch both mechanical properties behaviour with a promising performance (R\({}^{2}\) higher than 0.95), particularly those based on artificial neural networks. The fifth [7] and tenth [8] papers study the effects of applying nanomaterials to chemically stabilised soils, i.e., innovative materials with a promising future. In the fifth paper, [PERSON] et al. [7] studied the effects of using cellulose nanofibre (CNF) as an additive in Portland cement in the treatment for soft soil. Authors have concluded that CNF can mix the Portland cement evenly, hardly change the permeability, and reduce the variation in the strength, while at the same time, promoting an increase in the initial age and a reduction in the long-term strength development. In the tenth paper, [PERSON] et al. [8] identify the key parameters in the chemical stabilization of soils with multiwall carbon nanotubes (MWCNT). The characteristics of the surfactant (with an impact on MWCNT dispersion) and time (the importance of MWCNT diminishes as the stabilized matrix becomes denser and stronger) seem to be fundamental parameters which affect the geomechanical behaviour of the stabilized soil enriched with MWCNTs. From the study, the authors concluded that MWCNTs applied in a proper concentration and enriched with a specific surfactant type may be a short-term valid alternative to the partial replacement of traditional additives. The sixth [9] and eleventh [10] papers deal also with chemically stabilised soils, but now focusing on durability, quality control, and quality assurance issues. In the sixth paper, [PERSON] et al. [9] investigate the use of different materials (nano-magnesium oxide, ground granulated blast furnace slag, and rice husk ash) in soil stabilization to prevent ettringite formation (associated to volume increase), thus avoiding the deterioration of civil engineering structures. The results proved the potential of the nano-magnesium oxide-based binders (incorporating ground granulated blast-furnace slag and rice husk ash) as effective soil stabilizers, showing them to be valid alternatives to traditional binders. In the eleventh paper, [PERSON] [10] studies the importance of quality control and quality assurance (QC/QA)-related activities along the workflow of soil stabilisation projects. Based on the Japanese experience/results with mechanical mixing technology by vertical shaft mixing tools with horizontal rotating circular mixing blade, the current and recent developments of QC/QA are presented, which demonstrates their importance to clients and engineers. In the seventh paper, [PERSON] et al. [11] present an interesting study where a more sustainable alternative (xanthan-like biopolymer) is proposed to replace the use of Portland cement in soil stabilisation problems. The authors showed that a treatment with xanthan-like biopolymers or with commercial xanthan gum can be used to replace the Portland cement over the short term (curing time less than 14 days), although a greater level of effectiveness is obtained with the use of the commercial xanthan gum, due to its higher level of purity.
