New InLine Pave train: Leading technology, leading quality
Road rehabilitation at top speed: the new “Dash 3“ generation of the InLine Pave train shows just what it can do in practice. The unique combination of cutting-edge VÖGELE technologies lays the binder and surface courses in a single pass – a method which makes this recognized construction method particularly economical, too.
Rehabilitation “hot on hot”
A heavily trafficked motorway with severe damage requiring urgent repair: a job site on the German B9 is a typical case for InLine Pave from VÖGELE. That‘s because the paving train supports a unique construction method: the paving of compact asphalt pavements “hot on hot” – a process that makes road rehabilitation particularly simple and economical. This is because, with InLine Pave, the binder and the surface course can be laid in a single pass.
The excellent bond between layers also enhances the quality and resistance to deformation of the asphalt pavement. The cutting-edge technology involved comprises a mobile MT 3000-2i Offset PowerFeeder, a SUPER 2100-3i IP paver for binder course with the AB 600 TP2 Plus High Compaction Extending Screed and a SUPER 1800-3i paver for surface course.
InLine Pave boosts cost-efficiency and quality
“The challenges when rehabilitating roads frequently consist in minimizing the impact on traffic while improving economic efficiency for the client at the same time,” says Björn Westphal, Product Manager at VÖGELE. InLine Pave, a development by the global market leader, attests to the company‘s high applications expertise. The possibility of paving the binder and surface courses “hot on hot” is directly related to VÖGELE’s high-compaction technology: to ensure that the freshly laid binder course can be driven over by the surface course paver prior to compaction by roller, the SUPER 2100-3i IP paver for binder course is fitted with an AB 600 TP2 Plus Extending Screed. Inside the screed are two extremely high-compaction pressure bars operated by pulsed-flow hydraulics that ensure very high precompaction values.
Intensive interlocking of binder and surface courses
When paving with InLine Pave, the binder and surface courses interlock particularly intensively, creating a high-quality bond. After all, a perfect bond between layers is a fundamental requirement for the longevity of roads. With InLine Pave, the binder course is thicker while the surface course is thinner at 2–2.5cm.
The resultant pavement has higher degrees of density and fewer air voids following its subsequent final compaction by rollers. The surface course is consequently impervious to water and protects the binder course from harmful effects. The resistance to deformation under the influence of heat rises at the same time and this, in turn, helps to counteract rutting in the summer months.
Paving train also ready for use on conventional job sites
One important aspect when considering an investment in construction machinery is, of course, its capacity utilization. Thanks to its flexibility, InLine Pave machine technology is very much in its element in conventional applications as well. The SUPER 1800-3i paver for surface course and the MT 3000-2i Offset PowerFeeder are only slightly modified. The SUPER 2100-3i, too, largely makes use of standard technology. The transfer module for conveying the surface course mix into the material hopper of the SUPER 1800-3i is a special structure, but it is easy to demount.
InLine Pave featuring the innovations of the “Dash 3” generation
The two SUPER 2100-3i IP and SUPER 1800-3i pavers feature the latest innovations of VÖGELE‘s “Dash 3” paver generation – the machines that represent the new benchmark in energy-efficiency, operating comfort and pavement quality. Take the VÖGELE EcoPlus, for instance: the low-emissions package reduces exhaust emissions and noise levels as well as fuel consumption, taking efficiency to the next level. VÖGELE has also thought of the operators: the new paver operator’s and screed operator‘s ErgoPlus 3 consoles now integrate high-contrast colour displays, making them even easier to read.
Innovations of the new VÖGELE InLine Pave train
With the new “Dash 3” generation of pavers, VÖGELE have taken the binder and surface course pavers of the InLine Pave train to the next level of advancement.
The key innovations at a glance:
SUPER 2100-3i IP:
The most important innovation in the paver for binder course is the new transfer module for conveying the surface course mix to the downstream paver. The module has been extended by one metre. As with the MT 3000-2i material feeder, a diesel heater now maintains the mix at a constant temperature, preventing it from sticking to the conveyor. Also new is a second paver operator‘s platform with height-adjustable seats that can be swung through 90° beyond the width of the paver. All functions of the transfer module can be controlled from here using the paver operator‘s ErgoPlus 3 console. Two freely positionable cameras that ensure optimum all-round visibility help to enhance safety and quality. The process for demounting the module for conventional use of the paver has been simplified.
In the surface course paver, a new camera system improves the view into the extra material hopper, helping to avoid bottlenecks in the supply of mix. Like its predecessor model, the SUPER 1800-3i is fitted with a water spray system that prevents material sticking to the 40cm-wide crawler tracks. The machine can now be fuelled conveniently from the ground.
