Traffic circle inner rings made of precast concrete elements

Traffic circles are subject to heavy use compared to other traffic zones. The so-called inner rings or demand lanes are particularly affected by this. Up to now, these zones of traffic circles have generally been paved. This has disadvantages.

Buses and heavy goods vehicles in particular put a lot of strain on these zones, and the wear and tear is disproportionately high due to the enormous loads. However, unbound pavement construction methods can still be implemented in construction class 3-6 according to RStO, which is far from sufficient for the stresses that occur.

Fast and efficient

It saves time to plan and realize roundabouts with precast parts and further a lot of money. When roundabouts are installed, there are often problems due to shortage of space which make it impossible to redirect running traffic from the construction site. Fast processing is a decisive advantage for all parties.  

The new concept by FUCHS has an important benefit concerning construction time: Compared to the conventional construction time, assembly of the single elements can be carried out in just one and a half days. After three days already, the parts - which are laid in a gravel bed – are drivable and their color matches the environment. There is no faster, cheaper and more sustainable way to realize roundabouts.

Especially space saving: The traversable roundabout

For locations where space is not sufficient for a roundabout with inner rings and traffic island, specialists by FUCHS have taken their proven construction a step further.  

The inner ring is produced space saving in one complete precast part construction. The traversable inner ring is durable, can be quickly installed and is also drivable by transit buses and – if necessary – by heavy-duty traffic. The pavement structure and optical highlighting ensure that the inner ring is avoided by car and motorcycle drivers.
