Not much is happening on this section of the A45 Sauerland line, which is hardly surprising, given that Germany’s most famous motorway construction site is located just 30 km to the north: the 70 m high Rahmede viaduct near Lüdenscheid. The A45 motorway will remain fully closed there until spring 2026, with heavy goods vehicles and long-distance traffic taking the long detour via the Cologne Ring and the A1 instead. Here, at the Drolshagen exit, it’s quiet: no stream of cars, no heavy lorries thundering by every few seconds. The ten-strong paving crew from Dr. Fink-Stauf Civil and Road Construction are quite happy about that, as they can fully focus on their job—today it comes with a special challenge.
Tablets have been installed in the cabs of the BOMAG asphalt rollers and, for the first time, also in the operator’s station of the BOMAG BF 800 C-3 paver used here. In addition, eight temperature sensors are attached to the paver: four directly behind the screed, two in the auger chamber and one on the base. The eighth sensor is positioned at the front in the material hopper. The tablets are networked via radio, all of them running BOMAP Pave. The roller drivers are already familiar with the BOMAP app, but the new second dimension, BOMAP Pave, is something entirely new to them.
Stephan Schneider, a road builder through and through and today, the longest-serving person on site, is sitting in the paver’s operator’s station and has quickly familiarised himself with how the BOMAP app works: on his tablet he selects the ‘Live site map’ setting. From the different colours, he and his colleagues can immediately see where compaction is still required, how many compaction passes have already been carried out at each spot, and how many more are required.
He can also read off the asphalt temperature directly behind the screed, with the sensors mounted on the screed providing the values. The readings give him a good overview of the homogeneity of the paving temperature and enable the roller drivers to adjust their rolling behaviour to the current temperature conditions. If the temperature is already a little low, the roller drivers here should compact as soon as possible; if it’s still high, they can finish off the edges at their own pace further back. For him and his colleagues, BOMAP and BOMAP Pave are the perfect navigation tools. Everyone knows exactly what needs to be done next and where.
On their tablets, both paver and roller drivers always have the key parameters for the entire construction process in view. In addition, thanks to the continuous recording of these values, a clear picture of the paving quality can be generated. BOMAP Pave documents that the delivered mix was placed continuously at the right temperature and then optimally compacted—two key factors that significantly increase the quality and service life of the road.
BOMAP Pave enables asphalt pavers and rollers from all manufacturers to be networked in an open system, independent of brand. This makes it easy to record all key parameters seamlessly—across the entire paving process, from delivery of the mix to the fully compacted asphalt.

The planned paving volume for today has been calculated at 900 tons. Work begins with two 11 cm base layers. This is followed by an 8.5 cm binder course, with stone mastic asphalt as the paving material. Stone mastic asphalt is also to be used for the 3.5 cm surface course.
The stone mastic asphalt used here is characterised by its very high aggregate and bitumen content and offers outstanding resistance to deformation. Stone mastic asphalt is often the material of choice for laying binder and surface courses in the construction, rehabilitation or maintenance of motorways—especially here on the deceleration lane, where braking and turning vehicles generate particularly high shear forces. However, to achieve the required stability, the stone mastic asphalt must be compacted with particular intensity. Stephan Schneider’s team has scheduled a total of 4 days for this construction section.
In the past, I looked down on the paving work from up here, and everything was just black. Now, I simply look at the tablet and see the progress of the paver and rollers live and in colour—all in a single app. This helps me, and especially the younger colleagues with less experience.

On the A45, the Fink-Stauf team benefits both from BOMAP Pave and from the BOMAG paver’s operating concept, which impressed the paving crew. The extensive assistance functions of the BF 800 C-3 and its pre-programmed settings made their work considerably easier.
At the push of a button, the large BOMAG paver can be set to either transport or working position. The screed, levelling cylinders, auger and other components are automatically moved into the correct position. When starting or interrupting the work process, the screed is automatically unloaded, locked and returned to the floating position. This guarantees a consistently even and smooth surface during paving. Stephan Schneider only has to select the paving layer and the assistance system takes care of everything else: the scraper belt and auger intensity, screed temperature and tamper and vibration frequency are perfectly coordinated. In addition, the BF 800 C-3 screed is fitted with extra-long screed plates. These ensure optimum surface quality and asphalt evenness. At the same time, thanks to its high dead weight and the infinitely variable vibration and tamper frequency, the BOMAG screed can achieve pre-compaction values of up to 95%.
When speed and very high paving performance are required—up to 800 tons of material can be processed per hour—the BOMAG highway paver is in a class of its own, as the BF 800 C-3 is consistently designed for performance and reliability, user-friendliness and efficiency.
The BOMAG rollers following the paver ensured optimum compaction of the material. BOMAG BW 154 AP-4 and BW 154 AP-5 rollers were deployed at the Drolshagen junction. BOMAG’s pivot-steered tandem rollers have been setting new standards in asphalt construction for many years. In the new 5th generation, all functions can, for example, be preset, operated and monitored on a high-resolution, ten-inch, individually configurable touchscreen display. If the machines are also equipped with ASPHALT MANAGER, the driver only needs to select the layer to be compacted—the roller takes care of everything else: the amplitude self-adjusts constantly. This prevents bouncing and over-compaction of the asphalt layer, and with the integrated measurement of EVIB stiffness, the operator is always up to date on progress.
Stephan Schneider was satisfied with the outcome. What he sees looks good. In the next construction section further south, he would definitely use BOMAP Pave again, because measuring the paving temperature behind the screed with an infrared gun is now a thing of the past.
