Learning by doing

Trainees and instructors on a Wirtgen milling machine

The AZUBI techdays 2026

From 20 to 22 May, around 80 highly motivated trainees from across the Wirtgen Group came together at the Hamm AG brand headquarters in Tirschenreuth to independently realise their first real-life road construction project.

Held every year, the Wirtgen Group AZUBI techdays are a special highlight on the calendar of trainees in their third and fourth years of training and, at the same time, are an important investment in the future and the skill sets of our up and coming specialists. In the course of the three-day event, the participants translate theory into practice and learn what it means to bear responsibility for a real-world project and work together successfully as a multi-brand team. The highlight of the event is a road construction project that the trainees carry out largely on their own, with only minimal support and advice from instructors and service technicians. Here, they not only learn how machines and products from the various brands interact with one another, but also grow closer as a team. Core competencies such as teamwork, initiative, a sense of responsibility and problem-solving skills are actively communicated and developed. The program is supplemented by fascinating workshops, informative factory tours, and machine demonstrations. There was also plenty of fun when the day’s work on the construction site was finished: A varied evening program ensured that the three days would leave the young people with lasting memories that go far beyond the lessons learned at the event.

‘At our AZUBI techdays, our young talents don't just get to know the machines and technologies in real-world construction site conditions. The approach we take also helps develop soft skills such as teamwork, personal initiative and problem-solving abilities – core competencies that are also in enormous demand in the construction industry.’

Stefan Engl, Head of Vocational Training at Hamm

Step-by-step to the finished project

TIRSCHENREUTH/Bavaria: Hamm played host to the AZUBI techdays 2026. Despite a global outlook, the compaction specialist has never forgotten its roots and is always pleased to contribute to community projects in the region. This is why this year’s trainees are helping out at the local football club, ATSV Tirschenreuth. Here, the dilapidated access road and the forecourt of the clubhouse was in urgent need of renovation – and our trainees were able show the skills they have learned. After all, training to be part of a winning team is not only essential on the football field, but also at the Wirtgen Group. The project was backed from the start by the club itself and a local civil engineering contractor and demonstrated an outstanding collaborative effort on the part of the trainees, these project partners and the region.

Various machines from the Wirtgen Group were deployed during the renovation of the approximately 980 m² site. The project kicked off with the W 120 Fi from Wirtgen. This machine milled off the old surface layer precisely and left a level surface for paving with the Vögele SUPER 1800-5 X road paver. After paving, the Hamm HD 14i, HD 10e and HD 12e rollers took over and ensured an ideally compacted and cleanly finished asphalt surface layer. A total of 253 tonnes of asphalt mix was paved.

Day 1:

Precision milling

On the first day, the focus was on the preparation of the surface for paving. The trainees carried out precise profile milling work with the Wirtgen W 120 Fi.

In the process, the existing surface was selectively removed to a depth of between 2 and 10 cm to create an ideal foundation for the new asphalt layer. The milled material was put to sustainable use and used directly for bringing ancillary spaces up to the same level as the new paved surface– a practical example of resource-efficient working in road construction.

Day 2:

State-of-the-art asphalt paving in action

On the second day, the next phase was the paving of the new asphalt surface base course. For this, the team used a Vögele SUPER 1800-5 X road paver in combination with an AB 600-5 TV paving screed.

The trainees laid down a combined base and surface course with a thickness of 10 cm and were able to accompany and actively influence all steps of the process from material handling to paving and even distribution of the mix.

The trainees also experienced the logistical challenges that can arise on a construction site: due to the narrow access road to the site, the asphalt mix had to be delivered exclusively with 4-axle trucks, which required particularly precise coordination on the construction site. In all, 14 loads of asphalt were paved.

Compaction:

Creating visible quality

Several machines were used to ensure proper compaction, including the following tandem rollers: an HD 10e VV, an HD 12e VT and an HD 14 VO.

Here, the trainees learned just how important proper compaction is for ensuring the quality and durability of an asphalt surface and that it is a key element of the overall process. This was an example of the perfect interaction of teamwork and technology

‘Up until now, I was only familiar with the machines from our own factory. Now I’m really looking forward to seeing them working together with the machines from our group’s other brands.’

We win together

The future specialists worked hand in hand over a period of three days, but it was about more than just the construction process. The AZUBI techdays are also a platform on which young talents from the Wirtgen, Vögele, Hamm, Kleemann and Benninghoven product brands come together, learn from one another and have an opportunity to widen their horizons. The goal is also to deepen their understanding of how the products from the specialized brands complement each other perfectly in construction projects to achieve the best possible results, and how decisive cross-brand teamwork is for providing end-to-end services to customers.

‘It’s amazing that we got so much done in such a short time. And the best thing is that we don’t just stand by and watch, we get the chance to operate the big machines ourselves. That’s great!’

Celine Hoffmann, trainee from Vögele

‘My personal highlight was getting to the chance to operate a Hamm roller, – it’s such a powerful machine.’

‘During their training, it’s always important to us to show our trainees exactly why we do all this. Of course, that works much better on an actual construction site than it does on paper.’

Boris Becker, Head of Vocational Training at Wirtgen

The supporting programme

In addition to the training on the construction site, there were numerous workshops where the trainees presented their own factories to one another, machine demonstrations by Hamm and a guided tour of the compaction specialist’s entire factory.
