This is the first study on “ribbed smoked sheets (RSS)” as a geogrid reinforcement in geotechnical engineering. An RSS is a kind of natural para rubber. RSS (grade 3) was designed as a biaxial geogrid with an aperture size of 20 mm × 20 mm and a spacing of 20 mm. The RSS was found to be a significant functional layer when applied to the subbase lateritic soil layer. The lateritic soil with an RSS reinforcing layer was greatly improved regarding the California bearing ratio (CBR). Numerical simulation using two-dimensional finite element software was used to determine the optimal number and positions of the RSS reinforcing layers in road embankment stabilization. The simulation data in terms of horizontal displacement of unreinforced road embankments was validated by the collected data from the actual construction site. The RSS reinforced layer was varied from one to three layers under 61 analysis conditions. The highest safety factor was obtained with two layers of RSS at 0.1H below the top of the road embankment and 0.4H below the first RSS layer, suggesting a suitable installation of the RSS reinforcing layer. The RSS is thus strongly recommended as a reinforcing material in low CBR lateritic soil for the road embankment.

This research aims to assess the feasibility of project book Geotechnical Engineering assisted Plaxis 2D application which has a function as an increase in hard skills for the students in applying the concept of learning Geotechnical Engineering with Computer Application. The method of this research uses Research and Development with the development model is Borg and Gall. The subjects of this research are Civil Engineering students who take the subject of Geotechnical Engineering with Computer Application and the object of this research is a project book that will be validated by 2 validators (media and materials) and 1 practicality lecturer. From the three testing feasibility that have been done, and that have been obtained the results show that the teaching materials are feasible to be developed and practical to be used as an effort to bring up hard skills in the field of geotechnical.

“…Faced with these challenges, the use of geosynthetic reinforcement has emerged as a promising solution for preventing pavement deformation on unstable ground [23]. Recent research efforts have been aimed at studying the applications of geogrids in railway structures, with a particular focus on ballast and sub-ballast reinforcement [12], [19], [24], [24]- [28]. Geosynthetics are synthetic materials used to improve the geotechnical performance of soils.…”

This study assesses the effectiveness of geosynthetic reinforcement for flexible pavements on unstable ground. The methodology includes geotechnical data collection and modelling with Alizé LCPC and PLAXIS 2D 8.2. The results highlight the importance of geogrid reinforcement. Vertical deformations are reduced by the geogrids, with values of 3.44. m (phase 0 unreinforced), 2.65. m (phase 1 reinforced) and 2.07. m (phase 2 reinforced with reduced thickness). Horizontal deformations show an improvement of 117.07. % (reinforced pavement) compared with 51.54. % (reduced thickness). Vertical deformations showed a significant reduction, with 141.84. % (reinforced pavement with thickness reduction) compared with 171.32. % (reinforced pavement). In summary, geogrid reinforcement in flexible pavements offers an effective reduction in deformation. Combined with optimisation of the subgrade thickness, this strategy improves stability, strength and bearing capacity. This approach can be extrapolated to other road contexts for a better understanding of its benefits. Keywords: Geogrids, Deformations, Flexible pavements, Unstable soils
