Soil Bioengineering for Infrastructure Development in Cambodia: A Study on Vetiver Grass and Liquid Soil Catalysts for Road Projects

This report proposes a research program to determine the suitability of Vetiver grass for slope protection and the potential of liquid soil catalysts for improving soil-bearing capacity in Cambodia.

It presents the advantages of soil bioengineering for strengthening soil or slope structures and erosion control, which are important considerations in road and other infrastructure projects.

The report proposes six trials to be conducted on National Road 23 (NR 23) in Kandal Province and on Provincial Road 312 (PR 312) in Prey Veng Province.

The proposal for a comprehensive research program also emphasizes the need to develop knowledge products and increase awareness on soil bioengineering for infrastructure development.
