Honeycomb Retaining Wall - Road Construction Level 3

The video demonstrates the construction process of a honeycomb retaining wall for road construction at Rwanda Polytechnic. The first step involves laying a base of gravel and sand, followed by compacting the soil using a plate compactor machine. Instructor Eugene introduces the necessary tools, equipment, and materials required for the job, such as a plastic mallet, chisels, and safety goggles. Additionally, the video provides a tutorial on starting and operating a machine used for optimum compaction during the construction process. The honeycomb retaining wall is designed to prevent soil erosion and aid in drainage.
