The new Samruddhi Expressway, also known as Mumbai–Nagpur Expressway, is currently under construction and will connect the Indian cities of Mumbai and Nagpur on a total length of 701 km.

When completed, this expressway will link India’s largest container port JNPT in Mumbai to MIHAN in Nagpur simplifying import and export activities throughout the country. Additionally, interconnecting highways and feeder roads are constructed to connect all important cities and tourist places along this route.

The Samruddhi Expressway mahamarg project consists of 16 packages and was awarded to 13 companies: Megha Engineering & Infrastructures (Pkg-1&9), Afcons Infrastructure (Pkg-2&14), NCC (Pkg3), PNC Infratech (Pkg-4), Sadbhav Engineering (Pkg-5), Apco Infratech (Pkg-6), Reliance Infrastructure (Pkg7), Iron Triangle (Pkg-8), Larsen & Toubro (Pkg-10), Gayatri Projects (Pkg-11), Dilip Buildcon (Pkg-12), GVPR Engineers (Pkg-13), and Navayuga Engineering Company (Pkg15&16).

Wirtgen slipform pavers show their potential all the way

With a speed limit of 150 km/h, the expressway is the fastest in all of India, reducing the travel time between Mumbai and Nagpur from 16 to 8 hours. This calls for maximum concrete paving performance both in terms of output and quality to ensure the drivers’ comfort and safety on their journey. Along the whole 701 km, 16 Wirtgen slipform pavers SP 1600 were in operation to lay the concrete surface. Concrete is the ideal material for a gigantic project like this: It is cost-effective, extremely durable and requires very little maintenance. Over a working width of 15 m, pavement quality concrete (PQC) in a depth of 310 mm was used. The proper reinforcement could be managed by an automatic dowel bar inserter and 3 longitudinal tie bar inserters. These make sure that the cracks which are invariably produced as a result of stresses and temperature fluctuations are diverted into the concrete pavement in a controlled manner.

Highlights of Wirtgen slip form paver SP 1600:

• Working width of up to 16 meters (Special paving heights and widths up to 18.75 m are available on request.)

• Cost-effectively paves concrete surfaces for traffic areas, roadways, industrial areas or surfaces at airports, such as runways or taxiways

• Unparalleled concrete paving performance

• Long-term reliability

• Ergonomically designed, walkthrough operator’s platform for non-tiring, productive working

• High-powered, fuel-efficient diesel engine for concrete paving in the optimum performance and torque ranges

• Spreading plough for even distribution of the freshly delivered concrete in front of the inset paving mould

• Electrically driven vibrators for reliable concrete compaction

• Automated insertion of longitudinal joint tie bars to prevent the slabs from drifting apart

• Inset paving mould suitable for mounting between the track units, underneath the machine

• Pivoting legs for full adjustment of the track units to the conditions prevailing on site km (section 9 of 16) Used material – PQC (Wirtgen slipform pavers) | DLC (Vögele pavers) Working depths – 310 mm PQC | 150 mm DLC Working widths – Wirtgen slipform pavers 15 m | Vögele pavers up to 4.75 m.
