Road Subgrade Engineering
Road subgrade engineering forms the foundation of road structures, involving earthwork, slope protection, soft soil treatment, drainage systems, compaction control, and ground stability improvement. The quality of subgrade construction determines road bearing capacity, settlement control, and long-term operational safety in highways, municipal roads, mountain roads, port access roads, and mining transport routes.
