The Jordan Ministry of Energy and Mineral Resources (MEMR) was planning to build a petroleum strategic reserves terminal in the east of Amman, Jordan. They wanted to increase the petroleum storage capacity in the area, which required an increase in the base width of the embankment. The slopes of the embankment required protection from slope erosion.

The ramps of the grade separators are constructed either as embankments with natural slopes or as reinforced soil walls. In the case of partial walls, where sloped embankments are supported on reinforced soil walls, the embankment slopes needed to be given adequate protection against soil erosion, which could otherwise damage the fascia of the underlying reinforced soil wall and also induce seepage into the system. The slopes of the embankments were of the order of 30° with the horizontal. The reinforced soil walls supporting the embankments were as high as 10 m. The heights of the embankments were of the order of 5 m.

Monsoons in North Karnataka are notorious for damage to roads. The site was plagued with problems like reflective cracks, potholes, undulating surfaces etc., resulting in slow traffic movement and heavy vehicular damage. This stretch had to be rehabilitated time and again over the past several years, and no solution was proving to be long-term. Since the area is a major commercial hub, it was impossible to close off this section for an extended period completely, so a quick but long-term solution was needed.
