The content of large soil fractions in soils complicates the experimental part of the research, but, the modeling method makes it possible to determine the effect of soil filler on slope stability. The article presents the results of experimental study of the strength of coarse-clastic soils with different percentages of large fractions of gravelly soil (up to 20 mm) and aggregate (up to 5 mm) in the study of slope stability. The studies were carried out on three types of experimental equipment, which confirms the reliability of the results obtained. Recommendations are given for applying the values of the strength characteristics of coarse-grained soils in calculating the stability of slopes. The results of the tests are carried out in a tray and shear testing devices. Mixture of soil fractions from 2 mm to 50 mm. Purpose of the tests is to determine the actual parameters of soil strength j and C, taking into account the effect of impurities on the stability of slopes. Reliability of the results confirmed the comparability of the results of previous tests. Tray allows for testing models of slopes composed of mixtures of sand fractions from 2 mm to 20 mm. Model sizes slopes are defined relative to the size tray. Tray dimensions ‑ length 1400 mm, width 500 mm, height 1000 mm. The design of the shear device allows to investigate coarse soils of different factions. The diameter of the fractions were tested for shear device area of 100 sm2 is from 2 mm to 20 mm. The diameter of the fractions were tested for shear device area of 1000 sm2 ‑ from 5 mm to 50 mm. The experiments were performed in the laboratory "Geotechnics in Construction" in KazGASA.

The article presents the results of experimental study for types of loose soils are easily subject to dusting. In connection with this problem, the task is the study and study of the causes and structure of the formation of dustiness in the roadside zone of roads with common types of coatings or without coatings. The experimental study aims to determine the drying time of chemical dust prevention solutions under the influence of solar radiation and the norm of their distribution. The object of the research is dust generated on roads with low transport and operational performance (temporary roads in places of road repair work, roads to quarries, etc.), and materials used for dedusting road surfaces. The problem to be solved is to reduce the emission of a large amount of dust on roads without pavements or with inferior types of pavements, which adversely affects the human body. The results obtained are the identification of a way to combat dust on road surfaces, ensuring a decrease in wear when vehicles move on roads without pavements. At the same time, the classification of dust according to their sources of formation is expected at the output result. Due to their features and characteristics, these results allowed the author to solve this problem - effective ways to combat dust on road surfaces are: treating them with dust-removing materials that reduce wear; maintaining the original evenness; reduction of air pollution; improvement of traffic conditions for cars and the sanitary and hygienic condition of roads near settlements. For experimental tests, traditional salt solutions of various concentrations (NaCl, MgCl₂, CaCl₂, MgCl₂×6H₂O, etc.) and solutions of foreign–made stabilizing additives Durasoil and Soiltac from SOILWORKS were taken.

The paper presents the results of experimental studies of concrete and compressed reinforced concrete elements from cementless claydite-concrete. An experimental study of reinforced concrete elements with central and eccentric application of forces was carried out to determine their increased sensitivity. The construction material is cementless expanded clay concrete, obtained by a mixture of finely divided granular electrothermophosphorus slag. The tests were carried out on reinforced concrete compressed elements with central and eccentric application of longitudinal force to determine their bearing capacity. According to the test results, the strength and deformation properties of new concrete on a glass-slag binder and the calculation of reinforced concrete structures are checked. The selection of compositions of glass-slag claydite-concrete of various grades has been made. The use of concrete with a clinker-free binder in construction makes it possible to reduce the need for a scarce building material – cement. Studies of the physical and mechanical properties of glass-slag expanded clay concrete grades M50+M150 with a bulk density of 1,000–1,400 kg/m³ were carried out under a short-term static load. At the same time, the strength and deformation properties of glass-slag expanded clay concrete were studied under short-term action of compressive and tensile loads. The use of any new building material must be preceded by a comprehensive study of it – determination of its strength properties, study of concrete in the structure under load, etc. Building codes and regulations are adopted for the standard construction material, the properties of aggregates are not taken into account. Our studies show that the properties of fillers increase the strength properties of the structure when using claydite concrete on a glass-slag binder in reinforced concrete structures

As automation increases, mechatronic manufacturing systems require supervisory solutions that combine precise control, intelligent diagnostics, and intralogistics awareness. This paper presents a networked sensor–actuator–information architecture integrating model predictive control (MPC), Random Forest (RF)-based diagnostics, and logistics-aware coordination for automated mechatronic manufacturing systems. The main contribution is the explicit coupling of logistics-related supervisory variables with the predictive control problem and the diagnostic feature space. Buffer occupancy, transport delay, and logistics-induced waiting state are incorporated into an augmented reduced-order model to support constrained control and health-state interpretation. The framework is evaluated through a comparative simulation-based feasibility study using a low-order model of a robotic production axis affected by disturbances, degradation, and logistics-related constraints. The proposed approach is compared with classical feedback control, predictive control without diagnostics, and predictive control with diagnostics but without explicit intralogistics coupling. In the reduced-order simulation scenario, the proposed method achieved the lowest mean RMSE of 0.330 ± 0.015 and the lowest mean constraint violation rate of 3.133 ± 0.280% across 40 repeated simulation runs. However, the improvement in nominal tracking accuracy over the strongest diagnostic-assisted MPC baseline was marginal. Adding logistics-related diagnostic features improved mean accuracy from 0.848 ± 0.014 to 0.874 ± 0.012 and mean F1-score from 0.844 ± 0.016 to 0.872 ± 0.013. The main advantage of the proposed architecture was observed in reliability- and continuity-oriented indicators, including reduced downtime, lower final damage accumulation, fewer cooling cycles, and improved differentiation between machine-related and logistics-induced abnormal conditions.

Landslide activity represents a significant geotechnical hazard to mountain road infrastructure, particularly where roadbeds and pavement structures interact with unstable slope materials under complex geological and hydroclimatic conditions. This study assesses roadbed displacement and pavement distress at two mountain road sites in southeastern Kazakhstan: the Zharkent–Koktal-Arasan and Ayusai–Kosmostation highways. Field investigations included visual assessments of pavement and roadbed conditions, geodetic measurements of roadbed geometry and displacement, monitoring of pavement cracking, assessment of pavement technical and operational parameters, and characterization of geological materials. At the Zharkent–Koktal-Arasan site, the archived 2008 field dataset reported roadbed displacement of up to 4.5 m along the landslide-affected section. At the Ayusai–Kosmostation site, repeated surveys between 2021 and 2023 showed progressive development of transverse and longitudinal pavement cracking. Cumulative longitudinal-crack length increased at all monitored positions within the five test subsections, while the number of transverse cracks increased across all investigated crack-length classes. For one test subsection, an exploratory relationship between transverse-crack length and occurrence frequency was examined using three crack-length observations (R² = 0.987); this relationship is interpreted only as a descriptive site-specific trend. The results indicate that road deterioration at the investigated mountain-road sections occurs within a multi-factor geotechnical environment involving slope-material movement, water-related processes, climatic effects, and pavement and operational conditions. The findings demonstrate that slope–road interactions can be manifested through contrasting infrastructure responses, ranging from progressive pavement distress to large-scale roadbed displacement, and highlight the need to integrate slope, drainage, roadbed, and pavement monitoring in the management of mountain roads exposed to unstable geological conditions.
