Many friends and customers of our UHPCUltra High Performance Concrete material have repeatedly asked us in the past why there are streets, lanes, squares, etc. with UHPC Phalt (UHPC Phalt semi-flexible wearing course consist of an open-graded asphalt filled with high strength UHPC mortar) content that are exposed to extreme traffic and environmental conditions but are not race tracks.
We are big fans of automobile or motorcycle
racing. We are also very confident that we can
develop and deliver extremely good pavement
systems for high speed racetracks or city courses.
Unfortunately, we have no contact with the
operators, organizers or architects.
If you think about it, UHPC Phalt is a very
good solution for the strain of the racetracks.
With a standard road asphalt surface, the quality
can only be changed via the quality of the
asphalt. The new thing is that at UHPC Phalt 
the quality of the surface can be changed via
the quality of the asphalt and the UHPC. So
there are combinations that standard asphalt
cannot offer. In addition, the expected lifetime without loss of quality of the combination
covering is several times longer.
combination was to line roads, runways and
industrial roads with extreme traffic loads and
extreme environmental conditions with an
extremely hard and heavy-duty UHPC-Asphalt
combination. The implementation of this idea
was very successful, as the experiences of the
last 25 years show.
The UHPC Phalt material combination can
be set so that it is extremely abrasion-resistant /
wear-resistant or extremely load-bearing or
extremely resistant to temperature changes. In
city streets, the UHPC Phalt surface does not
lose its properties even after years of continuous traffic.
So there should be enough reasons to use thissurface on high-speed racetracks and street
circuit racetracks.
Technical advantages of UHPC Phalt
- Very high pressure resistant
- Extreme low material deformation
- Constant temperature resistance
from - 60°C/-76°F - +90°C/+194°F- Very simple and fast installation
- Very short curing times
- Can be laid on asphalt concrete or
similar substrates
- Installation with standard laying
machines
- Cheap material costs
- Extremely long durability
- Very high corrosion resistant
- Variable surface design
- Variable layer thicknesses
