*3.2. Construction Process*

According to the FCB construction process, the embankment slope was excavated to prepare a construction plane, and then drilling equipment was used to drill lateral holes to a designed depth in the embankment, which would not affect highway traffic operations. PVC plastic tubing or plug gauge was inserted in the hole to test the hole quality, and then the FCB material was cast in the holes, the holes were drilled in the embankment slop by the drilling machine as shown in Figure 3. A construction point worthy of attention is that the FCB pouring process should be implemented immediately after drilling the holes avoid a hole deforming under the overlying embankment load. The slope cover was cast using FCB material after all the holes were filled with FCB. The key point in this construction step is to cast the slope according to design's required proportional grading. Finally, the embankment slope was covered with soil and landscaped with plants.
