Racetracks must meet particularly stringent requirements in terms of evenness and slope. Wirtgen Group machines can be used for new construction and rehabilitation.

HAMM AG is a company in the WIRTGEN GROUP, a global group of companies in the construction machine industry with five main plants in Germany, local production facilities in Brazil, China and India, and a worldwide sales and service network. Within the WIRTGEN GROUP, HAMM AG is the specialist in rollers for the road construction and earthworks sectors.

In industrially developed countries, more roads are rehabilitated than new roads are built. But what happens to the old road surface? We know how to use it as a valuable resource.

The evenness and grip of the road surface are fundamental to the safety of racetracks. Learn how Wirtgen Group machines are used for rehabilitation.

Precise classification of a very wide variety of feed materials with maximum work output and fuel consumption as low as possible.

Even small changes can make a difference. We show you how efficiency and sustainability can be meaningfully combined – practicallky and effectively.

In the VÖGELE Auto Grade Plus system for automated grade and slope control, a unique levelling system is available that provides the basis for true to line and level paving on any substrate.

With Pave Assist Plus, VÖGELE takes the strain off site teams by allowing paving-relevant settings to be saved and called up again. Moving a Dash 5 paver between construction sections is also automated thanks to the assistance system.

If required, cement is pre-spread by a STREUMASTER binding agent spreader which is followed by water and binder tanker trucks. The milling and mixing rotor of the W 240 CR / W 240 CRi granulates the asphalt pavement layers. At the same time, the cement is mixed in and the water and bitumen emulsion or foamed bitumen are sprayed into the mixing chamber via injection bars. The processed construction material is conveyed to the rear of the machine by the primary conveyor and paved true to grade and slope by the integrated VÖGELE paving screed with a spreading auger. HAMM rollers then carry out the final compaction.

We explain asphalt paving – from delivery of the asphalt to paving by pavers and compaction by asphalt rollers.

The WR is equipped with a powerful milling and mixing rotor and state-of-the-art injection systems. The cold recycler mills and granulates the existing asphalt pavement, injects binders and water in precisely metered quantities and mixes all three in a single operation. The new base layers produced in this in-situ process are distinctive for their exceptionally high bearing capacity.
