The major OEMs have introduced the latest asphalt and concrete paving technology.
Equipment Times take a peek into the technology trends.
With more and more road building projects being planned and executed in India, all contractors are looking for faster methods for project completion. During FY 2017-18, concrete pavers demand increased by around 55%, according to V. G. Sakthikumar, Managing Director, Schwing Stetter India. He says, “Schwing Stetter has ensured that the best technology should be introduced in India and accordingly tied up with Gomaco Corporation who is the worldwide leader in concrete paving technology. This technology has very salient features which others don’t possess. Indian customers are very receptive to the latest technology and understand the value of mechanisation for good quality roads.”
“We are witnessing a strong growth for these products on the back of India’s buoyant road construction industry. Continuing government investments in roads and highways both direct as well as through the public-private partnership model make us optimistic about our future prospects,” says Ankur Tiwari, Senior Manager, Sales & Marketing, Ammann India.
Speaking about the latest trends Sakthikumar says, “Contractors around the world face the same job-site challenges, from short runs, tight radii and corners in parking lots, to a multitude of obstacles to pave around. Schwing Stetter India offers Gomaco’s Xtreme curb and gutter machines handle these challenges and can also slipform a 24 inch (610 mm) radius or less.The new Xtreme three-track Commander IIIx and two Gomaco 3300s with the exclusive Gomaco G+ control system feature rotary-sensored slew drives on the tracks, sensored leg positioning, and independent travel circuits to each track to allow tight radius slipforming.
Wirtgen Group has been involved with the road development in India since the Golden Quadrilateral days starting with the Mumbai Pune Expressway. Vogele has been the industry pioneer over the last 50 years and have introduced several new technologies like electric heating of screed, high compaction screed with pressure bars, spray jet, mobile feeder, In- line pave, Niveltronic plus for stringless paving etc. With technologies like in-line pave, we are able to pave both the dense bitumen macadam and the wearing course in a single pass operation, as hot on hot, thereby eliminating the tack coat and thus saving in the other costs,” states P. Ramesh, Managing Director & CEO, Wirtgen India. The width of the road and the density of traffic in terms millions of axle loads to be paved is one of the prime criteria in selecting a slipform paver, according Ramesh. He says, “For an existing state highway which is to be developed from single lane to two lane with shoulders, where the existing road cannot be disturbed due to ongoing traffic, the paving has to be done in 2 passes and you may have to select a paver with width of around 5 m, whereas for a new Greenfield project the paving can be done in a single pass where the no of lanes to be paved would determine the width of the paver required. Another important criterion for selection is whether the Dowel bars are to be inserted manually or automatically, though it is always recommended to use automatic dowel bar inserter to ensure the right quality. The type of the project and the timeline for execution also determines the type of machines to be procured.”
