Airport flooring, pavement and asphalt systems with UHPC

Airport - Flooring and pavement

Semi-flexible pavement combining systems like
UHPC Phalt combining the best properties of
asphalt and UHPC concrete. It is applied as an
asphalt based wearing course that hardens to a
matrix, in which the voids are filed with a UHPC
mortar. In this way, the UHPC Phalt system
combines the flexibility and freedom from
joints of asphalt with the excellent bearing capacity
and high wear resistance of the UHPC Phalt concrete.

Suitable for new build and renovation.

Such semi-flexible pavement 
combining systems are highly suitable for
 - Aprons
 - Push-back areas
 - Apron taxiway
 - Taxi-holding position
 - Refuelling areas
 - De-icing areas
 - Roads
 - Car parking area
 - Hanger area
 - Refuelling areas
 
Advantages of semi-flexible pavement systems
 - Even surface
 - No cavities
 - No cracks
 - No scaling
 - No large deformations
 - Excellent wear resistance
 - High bearing capacity
 - High thermal shock resistance

 - Service life - Fuel resistant
 - Minimum maintenance time
 - Very short curing time

Thermal shock resistant of UHPC material

Container with liquid nitrogen

We wanted to know how good UHPC Ultra
High Performance Concrete is at extreme
fast temperature changes.
We casted ten UHPC concrete plates with a
thickness of 25 mm /1 inch. The plates were
dried for 48 hours at room temperature
(20°C / 68°F).
No reinforcement was used.

The plates were cooled down from about
+20°C/68°F room temperature in a container
with liquid nitrogen (-180°C/-292°F ).
We waited until the plates were completely
cooled. All plates showed no cracking after
removing them from the nitrogen tank.
We immediately heated the plates with a
burner within 5 - 6 minutes to +250°C/482°F.

Even with this alternating load, there were no
cracks visible.
For the test we used a our standard UHPC
Cast material with quarz 1-3 mm sand as
aggregate.
