Jawaharlal Nehru Port (JNP) at Nhava Sheva, Navi Mumbai, is spread over 10 square kilometres and is the largest container port in India. State Highway SH-84 connects the JNP-Panvel Road junction to the ONGC terminal at Uran and experiences very heavy traffic movement. Due to heavy loads, the road stretch has always had issues of cracking and subsidence, requiring recurring and persistent annual rehabilitation.

Considering all factors for long term subgrade improvement, longevity and economy, StrataWeb® engineered solution was finalised. Considering the weak subgrade and the heavy loading, a solution using StrataWeb® style SW 356-150 mm cell depth was worked out. High strength polymer cable ties were used for cell to cell and flap to flap connections between StrataWeb® panels. The StrataWeb® cells were filled with GSB (Granular Sub-base) material.

The rapid installation of StrataWeb® and re-opening of the road to heavy traffic within record time was much appreciated by the PWD and more so by the ONGC Terminal. The entire stretch was satisfactorily completed in seven days with minimum labour and without disrupting the free flow of traffic. Other than diverting the traffic along the adjoining lane, no obstruction or diversion of the road was required, and no heavy machinery was needed.
