In September 2026, motorsport's premier class is scheduled to visit Madrid: the Circuito de Madring is currently taking shape in the north-east of the city, near the airport in the Barajas district. This new ‘Madring’ has one unique feature: the hybrid circuit combines existing exhibition centre roads with newly built permanent sections.
Building a race track is the ultimate discipline in asphalt road construction—unlike public roads, the permitted tolerances here are within just a few millimetres. At speeds of 300 km/h, loss of traction must be avoided at all costs. The asphalt must provide sufficient grip for high cornering speeds and maximum acceleration, withstand extreme mechanical loads and achieve the highest possible degree of homogeneity.
A consortium of Acciona and Eiffage is responsible for laying the base, binder and surface courses. BOMAG Ibérica is providing the machinery for the final compaction work. The paving team receives direct on-site support. The knowledge and experience of BOMAG's own experts help ensure the exacting asphalt quality requirements are met. The installation and use of BOMAP—an app for continuous compaction control that runs on standard Android smartphones and tablets—were also handled by a BOMAG service technician at the start of paving.
BOMAP is installed on all machines. The best possible results must be achieved throughout the entire compaction process. What is particularly important: BOMAP documents all key parameters of the compaction process at every stage.
The race track asphalt must be able to withstand the extreme forces generated during acceleration and braking. Here in Madrid, a special stone mastic asphalt mix is being used. Achieving the required evenness is one of the greatest challenges: the permissible tolerance is just 2 mm over 4 metres.
Project specifications were drawn up during the planning phase, covering raw materials, mix composition, working processes and quality assurance— all agreed with the FIA and monitored on site. The special texturing of the paving material creates a stable aggregate structure and maximum grip. Even in wet conditions, sufficient traction is maintained.
This asphalt mix must be compacted very quickly, and over-compaction must be avoided at all costs: it causes the aggregate to break down and the asphalt to lose its internal friction. The asphalt would then become more pliable and prone to cracking and deformation. The challenging job of final compaction is handled by BOMAG machines. Up to six pivot-steered tandem rollers from the AP-5 series are deployed simultaneously.
BOMAP, the smart app for continuous compaction control (CCC), is installed on each of the heavy BOMAG rollers. BOMAP provides access to a wide range of data relevant to the compaction process: EVIB value, frequency, amplitude, temperature, roller speed and direction of travel. On the job site, BOMAP acts as a navigation system for the roller operator. The app plots a live compaction map of the construction site. The operator can see at a glance where the asphalt has already been optimally compacted or whether further passes are required. This achieves highly uniform compaction across the entire surface, with all passes perfectly coordinated.
BOMAP makes continuous compaction control straightforward. The best part? The app requires no additional hardware and can be used straight after installation. And with BOMAP Connect, the compaction work of every machine on site is captured and monitored in a single networked system—not just that of individual machines.
Each of these highly advanced rollers from Germany is also equipped with ASPHALT MANAGER. Combined with infinitely variable amplitude, it enables BOMAG road rollers to work more powerfully and more gently in asphalt construction than conventional systems. They achieve the best possible performance with maximum flexibility.
The operator simply selects the layer to be compacted—the tandem roller takes care of the rest. The amplitude continuously adapts to the level of compaction already achieved, preventing drum bounce and the resulting over-compaction.
The quality standards demanded here can be achieved particularly quickly and efficiently— with only the number of passes that is genuinely necessary. At the same time, the direction-dependent control of the directed vibrator reduces bow wave formation, as the material is actively drawn under the drum.
BOMAP and ASPHALT MANAGER demonstrated their value to both roller operators and project managers. And there is one more feature the roller operators won't want to be without in future: myCOCKPIT—the operating concept and cab design of BOMAG’s heavy, pivot-steered tandem rollers.
myCOCKPIT enables the best possible work results. The machine shows you what's right. The key machine settings and measured values are visible at a glance on the touchscreen. Compaction progress—both current and over the last 25 metres—is also clearly displayed here as an EVIB value and in graphical form.
The touchscreen also provides fast, direct access to all important machine functions. The menus and displays are self-explanatory, with recommended settings pre-selected. The user interface can also be individually customised to suit any job site conditions. This is how myCOCKPIT makes day-to-day work even easier.
The asphalt paving demanded the utmost precision, and a strict schedule had to be met. In September 2026, the entire motorsport world will be looking to Madrid. The track layout promises extremely high speeds and sections that are unique in the racing calendar. The iconic highlight will be the banked corner 'La Monumental'. At almost 550 metres long and with a maximum banking of 24%, it will present a six-second high-speed challenge.
The asphalt here was compacted in crabwalk mode. By virtue of their design, only pivot-steered tandem rollers are capable of this. In this operating mode, the drum tracks only partially overlap, maximising the roller's contact area and reducing the linear load. The result: fewer marks in the asphalt and an almost perfect asphalt surface. At the same time, crabwalk lowers the machine’s centre of gravity—particularly important when driving and compacting on a banked corner.
In Spain, the asphalt rollers found on job sites are almost exclusively articulated machines. The fact that BOMAG was able to supply seven pivot-steered tandem rollers (one as a standby unit) made the project possible.
One thing has become clear in Madrid: BOMAG's heavy, pivot-steered tandem rollers from the AP-5 series are exactly the right machines for this very special job. And the combination of decades of experience in asphalt road construction with first-class, no-fuss service makes BOMAG Ibérica a reliable partner even for the most important projects on the Iberian Peninsula.
