“…A rock drilling machine is employed to vertically bore a hole into the slope, reaching the stable bedrock area within. Subsequently, an anchor rod is inserted, and cement mortar is injected into the hole to establish a cohesive connection between the anchor rod and the slope structure [44]. This technique aims to enhance the strength of the slope structure.…”

Life cycle assessment (LCA) plays an increasingly important role in environmental management, particularly in promoting energy and carbon-conscious practices across various disciplines. This review provides an overview of the latest innovations and potential benefits of integrating LCA into ecological slope treatment strategies. This study explores new developments in LCA methodology and its application to slope treatment, aiming to improve the integration of infrastructure development and environmental stewardship. Through an extensive review of over 120 peer-reviewed journal articles and a critical analysis of the intersection of LCA with slope treatment, this paper identifies innovative techniques that have the potential to significantly reduce the environmental impact of slope management. The review emphasizes advanced LCA practices that quantify and mitigate carbon emissions throughout the life cycle stages of slope treatments. Key findings demonstrate that LCA enhances the methodological rigor in assessing ecosystem services and impacts, and reveals new strategies that emphasize the importance of ecological considerations in infrastructure projects. Future research directions focus on refining LCA data acquisition and promoting a standardized knowledge base to support precision in ecological impact assessments. In conclusion, the adoption of LCA in slope treatment is imperative for aligning industry practices with global sustainability targets, emphasizing the importance of integrating uncertainty analysis and long-term impact assessments to bolster the credibility of LCA outcomes.

“…Geogrids, consisting of solid networks of synthetic material, play multiple roles in slope stabilization, including reinforcement, separation, drainage, filtration, protection, and containment [ 5 , 6 ]. Each of these functions is fundamental to improving the overall stability of slopes and optimizing their performance under various environmental and load conditions.…”

This study aimed to investigate the sustainable use of recycled plastics, specifically polypropylene (PP) and high-density polyethylene (HDPE), in the manufacture of geogrids for geotechnical and civil engineering applications. Plastics were collected from a recycling center, specifically targeting containers used for food, cleaning products, and other domestic packaging items. These plastics were sorted according to the Möbius triangle classification system, with HDPE (#2) and PP (#5) being the primary categories of interest. The research methodologically evaluates the mechanical properties of PP/HDPE (0/100, 25/75, 50/50, 75/25 and 100/0% w/w) composites through tensile and flexural tests, exploring various compositions and configurations of geogrids. The results highlight the superiority of pure recycled HDPE processed into 1.3 mm thick laminated yarns and hot air welded for 20 to 30 s, exhibiting a deformation exceeding 60% in comparison to the PP/HDPE composites. Through SolidWorks® Simulation, it was shown that the adoption of a trigonal geogrid geometry optimizes force distribution and tensile strength, significantly improving slope stabilization efficiency. Based on the results obtained, a laboratory-scale prototype geogrid was developed using an extrusion process. The results underscore the importance of careful composite design and yarn configuration selection to achieve the desired mechanical properties and performance in geogrid applications. It emphasizes the potential of recycled plastics as a viable and environmentally friendly solution for stabilizing slopes, contributing to the reduction in plastic waste and promoting sustainable construction practices.

“…Current research on slurry masonry schist slope protection has focused on the overall stability of slopes [1,2], and several scholars have established slope models through numerical simulation software to study the effects of freeze-thaw cycles, herbaceous root systems, and other factors on slope stability [3][4][5][6]. Several scholars have achieved good results by designing lattice beams and anchor cables to improve the overall stability of slopes [7][8][9][10]. Slurry masonry schist, a combination of schist and mortar, is different from ordinary concrete.…”

This study used a static bidirectional multifunctional loading system. The system conducted bidirectional compression tests on scaled specimens of slurry masonry schist under freeze–thaw cycling conditions. This study aimed to investigate the influence of bidirectional stress coupling with freeze–thaw cycles on the mechanical properties of slurry masonry schist. The results indicate that lateral pressure can increase the peak stress of slurry masonry schist, while freeze–thaw cycles have an adverse effect on the material’s internal pore structure, counteracting the gain effect of lateral pressure. This study also employed acoustic emission (AE) technology to analyze the evolution of slurry masonry schist failure characteristics. The findings reveal that freeze–thaw cycles accelerate the failure of slurry masonry schist during loading, and lateral pressure to some extent mitigates the damage development of slurry masonry schist. The synergistic effect of lateral pressure and freeze–thaw cycles alters the fracture mode of slurry masonry schist. Acoustic emission signal localization demonstrates numerous AE localization points in the interface transition zone, forming a coherent signal band where cracks propagate toward complete interface penetration. The crack extension process of the slurry masonry schist was investigated using the digital image correlation (DIC) method. The results indicated that macroscopic cracks formed in the strain localization zone, resulting in fracture damage to the specimens, with interfacial debonding identified as the primary failure mode for slurry masonry schist structures.
