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.
