Wirtgen SP 1600 Slipform Paver Sets World Records During Concrete Paving In India

During the construction of a motorway between the major Indian city of Vadodara and the global metropolis of Mumbai, the Wirtgen SP 1600 was able to demonstrate its impressive performance potential and set four world records. The major Vadodara-Mumbai Expressway project is part of the 1,350 km Delhi-Mumbai Expressway linking India’s capital New Delhi and Mumbai. The construction project is part of the country’s National Highways Development Project, passes through six states and due to its size, has been divided into more than 50 individual sub-projects awarded by the National Highways Authority of India (NHAI). Initially, the roadway will be widened to eight lanes, with four lanes in each direction. Looking ahead to the future, however, sufficient space has been set aside in the middle of the road to allow four additional lanes to be added.

Using Flexibility And Innovative Strength To Create Customised Solutions And Achieve Maximum Productivity

The SP 1600 slipform paver cost effectively paves concrete surfaces for traffic areas, roadways, industrial areas or surfaces at airports, such as runways or taxiways, with a working width of up to 16 metres and with unparalleled precision. It can be used, for example, to pave full-width motorways in a single pass.

But sometimes even that isn’t enough. Thus, the team from Wirtgen R&D department worked closely with Patel Infrastructure Pvt. Ltd. to develop a customised special solution for the company. The machine and in particular, its concrete unit, was extended to a working width of 18.75 metres. This involved, on the one hand, additional extension elements for each component, including the extremely complex dowel bar inserter. On the other hand, the machine has to be able to compensate for the enormous amount of additional weight and still be capable of high-precision levelling. The TCM 180 texture curing machine was also adapted to the working width of 18.75 m in order to apply a dispersion to the concrete surface behind the slipform paver as protection against evaporation.

One-Of-A-Kind Support Around The Globe From The Wirtgen Group Service Team

To ensure that the customised machine always ran smoothly, the construction project was supported by four Wirtgen technicians. Every hour, a total of 45 transport vehicles delivered concrete to the construction site to provide the slipform paver with sufficient material. In order to be able to process this enormous quantity of concrete in such a short time, the paving process had to be carried out at an average speed of 1.8 m/min. Approximately 30,000 dowel bars and tie bars were inserted using the built-in automatic dowel bar inserter (DBI) and the central tie bar inserters (CTBI), providing the structure with the necessary stability and ensuring that the slabs are bonded together properly to withstand traffic loads for many years to come.

SP 1600 Inset Paving Train On The Road To Success

The world records speak for themselves. With its specifications, the SP 1600 is synonymous with unparalleled concrete paving performance. But long-term reliability also plays a critical role on the road to a successfully completed project. As such, the slipform paver was not only able to complete its work on the section measured for the world record, but now, in the meantime, this entire stage of construction. The slipform paver team from Patel Infrastructure has many more miles to go in this major project, however, and continues to rely on the Wirtgen SP 1600 paving train.
