National Highways Authority of India

PRODUCT USED

StrataBlock™ and StrataGrid (SGB)

APPLICATION

Construction of Reinforced Soil wall

About the project

The section of NH-4 connects the thickly populated regions of Tumkur and Chitradurga in Karnataka. The National Highway Authority of India adopted this section for widening to six lanes.

 

Considering the terrain and sub-soil conditions, designing and constructing the approaches on filled up / raised foundations was necessary. The conventional solution of RCC retaining walls was costlier and time-consuming, besides possible disruption of traffic.

Strata’s geosynthetic experts suggested RS wall construction using non-plastic soils available in the region, StrataGrid™ PET knitted geogrid soil reinforcement and StrataBlock™ precast segmental concrete blocks as fascia. The founding levels of these walls had to be raised to meet technical requirements and economise the construction cost. The reinforced soil material was also used for these berms. Construction of both, RS walls and berms was carried out with stringent quality control.

The use of StrataGrid™ and StrataBlock™ fascia resulted in a cost reduction compared to the conventional RCC retaining walls. The system also facilitated easy construction of roads within minimum time.

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.
