CLIENT

Road Infrastructure Agency, Bulgaria

PRODUCT USED

Geogrid and StrataGrid™

APPLICATION

Embankment reinforcement over soft subgrade

About the project

The client stipulated the need for a fast-track geotechnical solution to assist in constructing an embankment for a new highway between Hemus University and the town of Hemus, Jablanica. The primary challenges of this project were completing it within a short timeline and ensuring minimal environmental impact during construction.

StrataGrid™ was utilized as the solution for soil reinforcement of the retaining structures with low excavation volume. This not only provided economic benefits but also helped complete the work within the limited time period.

The reinforced soil system was designed to last up to 120 years. It was constructed using a fortified soil structure with a fascia consisting of double twisted hexagonal wire mesh and anti-corrosion coating.

The strengthening facility consists of two parts. The foundations are filled with gabion modules with a vertical stone face up to 1 m high. The second zone is 26.0 m high and consists of factory modular fascia systems with a 70° slope angle face. It is then layered with 30 cm of fertile soil that supports vegetation.

Reinforced soil structures using StrataGrid™ are widely used globally due to their strength, durability, and longevity. These structures are designed to conform to international standards and are cost-effective. Consequently, StrataGrid™ was selected as an innovative solution for this embankment construction.

StrataWeb® geocells – A slope erosion protection system for embankments

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.

Slope protection of partial wall on flyover using StrataWeb® geocells

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.

Rehabilitation of road in the busy city town centre in Karnataka

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.
