Experimental and Numerical Investigation of Reinforced Soil Slopes With Vertical Rib and Inclined Reinforcement: Application to Embankment Slopes

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Reinforced soil technology is widely applied in slope stabilization, yet the optimal configuration of reinforcement remains a key design challenge. This study presents a comprehensive investigation of vertical rib‐reinforced and inclined‐reinforced geogrid layouts through scaled physical model tests (1:10) and finite element simulations using MIDAS GTS.

Tests of geosynthetics-reinforced ballast stressed state under heavy trains [PDF]

MATEC Web of Conferences, 2019
Nowadays requirements for strength and stability of railway subgrade are increased. It occurs due to raising of train speed and axle load. Some sections of subgrade that were previously considered stable do not satisfy safety requirements. In this regard,

Evaluation of the Performance of a Composite Material Made From Lateritic Soil, Crushed Granite, and Cement for Use as the Base Layer of Road Pavement

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
The base layer is important for the road pavement structural performance. This study aims to monitor the performance of various local composite materials as road construction materials. To do this, an experimental study treated the improvement of geotechnical properties of a lateritic gravel, initially nonadopted as a base layer, by using three ...
