Evaluation of Erosion Resistance of Embankment Lining Materials Mixed With Solidified Materials to Overtopping Flow

Key Points

• The research aims to evaluate how the amount of solidified materials affects the erosion resistance of covering materials used in embankments.
• Conducted overtopping experiments to assess erosion resistance
• Compared erosion resistance of solidified materials mixed in covering materials to grass-covered controls
• Utilized established methods and guidelines by the Ministry of Land, Infrastructure, Transport and Tourism.
• Covering materials with over 150kg/m3 of solidified materials show equal or better erosion resistance compared to grass
• Materials with 100kg/m3 may have inferior erosion resistance compared to grass, indicating potential limitations.
