The amplification of urban development and the extension of road networks necessitate a comprehensive understanding of various soil improvement techniques for civil engineering applications. Soil enhancement methods, typically trusted and practical, are pivotal in addressing geotechnical engineering challenges. This study focuses on the numerical evaluation of the efficacy of geogrids and recycled concrete aggregate (RCA) in the stabilization of road embankments. Critical soil properties such as water absorption, soil erosion, and settlement susceptibility are significantly improved through these methods, promoting sustainable land use, environmental conservation, and infrastructure durability. Literature reveals that the use of geogrids or waste materials like RCA contributes effectively to soil layer enhancement. In this investigation, road embankment models, with and without the aforementioned improvements, were developed and assessed under vehicular load conditions. The findings demonstrated that the incorporation of geogrids or RCA significantly bolsters the stability of road embankments. A noteworthy reduction in vertical settlement, up to 45%, was achieved when geogrids and RCA were concurrently utilized in the embankment. This suggests that these methods, individually or in combination, could provide a viable solution for enhancing the performance and stability of road infrastructures. Further research is proposed to explore the long-term performance of these enhancement methods under various environmental and load conditions.

Received: 21 September 2020 Accepted: 10 March 2021 In this work, we have studied the Kaolin M1 and M2 by the X-ray diffraction method, and we have focused on mullite phase which is the main phase present in common in both products. An update of the program of the method of Stokes was carried out, it was necessary to the microstructural analysis. The completed version is less sensitive to the choice by excess of the number of coefficients of Fourier with regard to the effect of truncation and the office plurality of the errors. The determination of the symmetry of the cell of the principal phase (mullite) in the studied fritted Kaolins was carried out. In Kaolin M1, the size of crystallites of the dominant phase varies between 80 to 170 Å. In Kaolin M2, the size of the crystalline grains of mullite varies between 100 to 400 Å. The size of crystallites was confirmed by the joint method of Williamson-Hall. A distribution of sizes of crystallites was carried out. It shows a dominance of the size of approximately 140 Å for the principal phase of Kaolin M1 and a dominance of the size of approximately 230 Å for the same principal phase of Kaolin M2. By the study of the profiles of line by DRX, it appears very clearly that the principal phase of the various sintered Kaolins, mullite, is free from internal microstrains. It is the case of the mixtures fritted not only at low temperature (1100°C) during 1 hour but also the case of the mixtures of the type ‘chamotte’ cooks with 1350°C during very long times.

Received: 4 January 2021 Accepted: 11 March 2021 Friction stir processing (FSP), compared to other solid-state processing methods, is a one-step process that attains refinement and homogeneity in its Microstructure. The complex configuration of various kinds of welds in FSP and their 3-D (threedimensional) nature makes it tough to develop an overall system of ruling equations for theoretically analysing the functioning of the friction stir processed materials. The experimental trials are usually expensive and time-consuming. These hurdles can be overcome often by doing numerical analysis. The mechanical and microstructural characteristics of the Stir-Zone can be precisely supervised by enhancing the parameters of tool design, material properties, parameters of friction stir processing, and active heating and cooling. In this study, the significance of process parameters during FSP of Aluminium 5083 and the role of numerical analysis using ANSYS Workbench in the prediction of material behaviour have been discussed.
