32° and getting hotter.

Summer in Brandenburg, cloudless skies in the Havelland north of Potsdam. “If we keep this pace, we’ll be on the other side just after noon!” says Olaf Rubert, Managing Director of Rubert Straßen- und Tiefbau GmbH, as everything is running smoothly. Laying of the four-centimetre asphalt surface course is in full swing.

The Berlin-Marzahn-based company is frequently active in the surrounding region of the capital. Today, they're working on the BAB10 motorway, specifically on the Havel Bridge, commissioned by Autobahn GmbH des Bundes (Northeast Division). Olaf Rubert and his 20-strong crew are operating two feeders, two asphalt pavers and six articulated tandem rollers—all BOMAG machines.

Motorway rehabilitation north of Potsdam.

Vehicles have been crossing the Havel here for almost 100 years. At this point, the river looks more like a lake— the bridge spans an impressive 706 metres from one expansion joint to the other. In the 2000s, the superstructure of the Nauen carriageway was replaced with a new steel structure. Now, in the summer of 2025, the next resurfacing is due.

The Havelland Bridge has to withstand more than 32 million 10-tonne axle crossings every year—and these figures make one thing clear: The bridge surfacing has to cope with extreme demands: not only must it absorb the stresses of traffic, especially heavy goods vehicles, it must also transfer these loads to the supporting structure, endure the constant movement of the vibrating steel bridge, resist both cold and—as today—heat, while always remaining even and skid-resistant.

Continuous hot-to-hot paving.

Here, a special asphalt mix with polymer-modified bitumen is being laid. “Each ton of this material costs 150 euros. We’ll be laying almost 1,000 tons today,” explains Olaf Rubert. “But with the support of BOMAG's Berlin branch, that's no problem.”

Five machines have been supplied today by the BOMAG rental service; one paver and one tandem roller come from Rubert’s own fleet. Two BOMAG application engineers are also on site, providing hands-on support to the paving crew. They had already visited the site the day before to set up the machinery. For Olaf Rubert, this customer proximity is what counts. It's something he wouldn't want to do without and has relied on for many years— mutual understanding and mutual support.

Paving on the mastic asphalt protective layer is progressing rapidly at a steady paving speed. Just how it should be. Further back, work on the road markings has already begun. Despite congestion on the BAB10, the supply of asphalt mixture to the site is smooth and uninterrupted. A decisive factor in achieving the required asphalt quality. Final density testing will later be carried out using core samples.

Two BOMAG BMF 2500 S material feeders are in operation on the site. Each equipped with the short 1.2-metre-wide conveyor, they can transfer up to 27 tons of asphalt to the paver in just 35 seconds—ensuring high output. The chain-reinforced conveyor ensures reliable material transfer without downtime. In addition, the feeders’ hoppers are designed with a capacity of more than 15 tons—ample for rapid truck changeovers. This keeps truck changeover times to a minimum.

The asphalt mix is laid by two large BOMAG pavers. They form the core of the yellow paving train. The BF 700 C-3 machines, with their optimum balance of productivity and flexibility, deliver all that’s required for efficient, high-quality road construction. Thanks to the all-round view from the operator’s platform, they also offer a clear advantage in safety and comfort.

This concept is called ADVANCED Pave, and it makes the paver operator's work even easier by presenting all machine- and process-relevant functions clearly at a glance and enabling direct access. It also allows key functions of the paver to be automated with ease.

BOMAG rollers with ASPHALT MANAGER.

Alongside the pavers from Boppard, Rubert Straßen- und Tiefbau GmbH now also uses the latest generation of BOMAG tandem rollers—because whether it's the surface, binder or base course, one thing is certain: with BOMAG articulated asphalt rollers, outstanding compaction results can be achieved with a minimum number of passes. Thanks to their split drums, generous drum offset and five steering modes, the machines are also highly versatile.

The heavy articulated BOMAG tandem rollers used here on the Havel Bridge carry the letters AM in their product names. That stands for ASPHALT MANAGER.

ASPHALT MANAGER technology works with the proven directed exciter system. In this case, the compaction forces are regulated according to the EVIB value, with continuous target-actual comparison. As the measured value approaches the target, the forces applied are progressively reduced. This prevents sudden jump operation.

But BOMAG rollers with ASPHALT MANAGER can do even more: on the Havel Bridge, the BOMAG rollers are working in manual oscillation mode. This deactivates automatic control; the directed exciter applies only horizontal forces in oscillation mode—with no vertical amplitude. As a result, the drum remains in constant contact with the asphalt surface, and compaction is particularly gentle.

Thanks to ASPHALT MANAGER’s maximum versatility, all applications can be covered—right up to pure oscillation. BOMAG tandem rollers equipped in this way make light work of jobs on bridges, in sensitive areas or directly alongside buildings.

Greater operating comfort for the driver.

The latest generation of BOMAG tandem rollers is the Rubert crew’s absolute favourite workplace. The rollers impress with their performance and provide the working comfort demanded in asphalt road construction.

A special feature is the optional comfort seat with built-in seat ventilation, which is running flat out in today's 32-degree heat.

The machine design and all equipment options have been thought through down to the last detail. BOMAG’s myCOCKPIT philosophy is designed to make roller operators’ daily work easier—and more comfortable. For example, the display elements on the control panel can be arranged individually and personalised to suit the needs and preferences of different operators.

The windscreen is particularly large and extends low down. From the side seating position, the operator can see the drum edge even with the window closed. So the side windows can remain closed at all times, and the cab can be air-conditioned without difficulty. A blessing when, as forecast around Potsdam, temperatures are set to hit 40 degrees in the coming days.
