- Abstract
Road subgrade earthwork engineering requires a large amount of high-quality filling materials. The extensive exploitation of natural resources causes environmental damage. Based on a highway construction project in the Gobi Desert, this study utilized aeolian sand as the filling material for road embankments. Mechanical properties, compaction characteristics, and shear strength characteristics experiments were conducted to explore the stability of sand-filled embankments. The research revealed that the stability of sand-filled embankments depends not only on the composition of the proper structure, including the sand-filled core, surrounding zone, geotextile, and capping layer but also on factors such as the embankment height, slope ratio, roadside protection method, and quality control in the field. The findings of this study serve as a valuable reference for future similar highway construction projects.
