This year has seen a wide array of innovative additions to the asphalt paving market - Mike Woof reportsThe worldwide asphalt paving market is both competitive and complex, with an array of important players jostling for position. At the same time, paving controls have taken a great leap forward with the development of accurate 3D systems that can use a combination of laser and GPS positioning. Leica Geosystems,
Meanwhile the paving equipment machine market is broadly split into two technologies, developed in Europe and North America, with the former featuring tamper bar screeds that deliver pre-compaction and the latter using screeds aimed at high production throughput.
This year has seen major developments in terms of new products, with numerous manufacturers developing innovative machines. At the
The company also offers the 312 wheeled model, a mid-small size paver that weighs 13.2tonnes and can deliver 420tonnes/hour. Power comes from a JCB diesel delivering 85kW and this machine offers paving widths of 2.5-5m and up to 7m with mechanical extensions. Meanwhile the compact 308 wheeled machine has a
Vögele has made key model introductions to its paver range in 2010, both at the top of the line-up with its powerful Super 3000-2 and with its new compact machine, the Super 700. Taking the place of the Super 600 launched in 2006, the new Super 700 retains the compact dimensions of its predecessor, but has been improved. Power now comes from a Deutz diesel delivering 45kW while maximum paving width has been increased to 3.2m and it offers a maximum output of 200tonnes/hour. The machine can be operated in narrow working applications as it has a track width of just 1.1m, allowing a clearance width of 1.2m, while it also has an asymmetrical material hopper. With its compact dimensions the Super 700 suits jobs such as paving over backfilled trenches or repairs to minor roads and parking areas. As it has a low emission engine, the Super 700 can also be used for paving in underground or multi-storey car parks.
The machine is fitted with Vögele's AB200V extending screed, which is equipped with vibrators and has been specially designed for use with this paver model. When retracted the screed is 1.1m wide and extends hydraulically up to 2m, while bolt-on extensions allow a maximum paving width of 3.2m. For jobs such as covering over trenches, a novel paving width reduction system allows the machine to lay an asphalt mat just 0.5m wide. The operator can reduce the pave width to any size from 1.1-0.5m, while as the screed floats on the mix in this narrow working configuration, the firm says that optimum pre-compaction can be achieved. Like the larger screeds in the Vögele range the AB200V features electric heating that is said to deliver uniform heat distribution across the centre screed plates, the extending units and bolt-on extensions.
