Taxiway repair at Brussels-Zaventem Airport (BRU), 2019 (1050)

2019-08-16T09:31:09+01:00

Initial situation Brussels-Zaventem Airport is the largest airport in Belgium with over 25 mio passengers and is additionally also used for military operations. The apron area was originally constructed as a durable concrete surface but developed damages in the highly frequented areas after many years of use. Some of these areas were repaired using asphalt patches. One of these damaged areas was on a taxiway connecting 12 airplane stands with the runway. The asphalt patches quickly developed cracks and depressions due to creep and tire tracks from the weight of the aircraft. Therefore, the patches needed replacement with a [...]

Airfield repair at Václav Havel Airport Prague (PRG), 2017 (1013)

2019-08-15T14:03:11+01:00

Initial situation With over 15 million passengers each year, Václav Havel Airport Prague is one of Europe’s busiest airports and at the same time, it has a relatively small size. This makes airside areas very valuable for smooth operations and closure times problematic. In order to reduce possible closures from multiple weeks to only hours or days, the airport operators wanted to try out a new solution with Concretum® rapid-hardening concrete. For the first time in the Czech Republic, two damaged slabs of totally 16 m3 were replaced at the airplane stands. Solution and assessment The Václav Havel Airport [...]

Repair of stands at Charles de Gaulle (CDG), 2017 (1001)

2019-06-14T09:53:31+01:00

Initial situation On Paris’ largest airport Charles de Gaulle (CDG) with more than 65 mio passengers per year each and every pavement area is continuously used by airplane traffic. Additionally, construction works and temporarily diverted taxiways constrain operations. There is hardly any time or space for repair and maintenance of deteriorated areas of the concrete pavement. Solution and assessment Thanks to the highly flexible application of Concretum rapid-hardening concrete Q-FLASH 2/20, concrete bays can be reconstructed as a whole or in parts. Adjacent areas are not affected and can be used for traffic without restrictions. The deteriorated old concrete is [...]

Repair at India aircraft stand areas ZRH 2015, Zurich Airport (896)

2019-06-14T09:53:32+01:00

Initial situation At Zurich Airport five concrete slabs in a row had to be replaced on the taxiways between the runway and the India laircraft stands. As is customary for airport works, the renewal works had to take place at night to avoid the disruption of flight operations. Solution and assessment This was the first time in Switzerland that Concretum® Q-FLASH 2/20 was poured with a slipform paver.
The paver has an adequate paving width which allowed the 7 m wide and 35 m long surface unit to be poured in one piece. This degree of automation facilitates an increased [...]

Repair of concrete surfaces at Frankfurt Airport, Frankfurt am Main, 2014 (772)

2019-06-14T09:53:32+01:00

Initial situation During repairs at Frankfurt Airport, the concrete surface of a roadway used by vehicles and crossed by aircrafts had to be renovated. The area to be renovated was located at the heart of the Airport at Terminal 1, between piers A and B. For this reason, it was very difficult to set up a barrier for the construction works. Only very short windows were available for repairs at the airport, because of the need to maintain daily operations. Repair works could only be carried out therefore, during night closures between 23:00 and 05:00.  Since vehicles would have [...]

Repair to taxiways ZRH 2015, Zurich Airport (896)

2019-06-14T09:53:32+01:00

Initial situation At Zürich Airport, a number of slabs of the taxiways showed signs of fatigue as well as damage requiring repair. In order to minimise closure periods, the repair works were carried out during a nighttime slot. In this way the available window was severely restricted. In addition, the exceptionally hot summer in Zürich presented a further challenge to concrete production. Solution and assessment For this project, the rapid-hardening concrete, Concretum® Q-FLASH 2/20, was used. It reaches a compressive strength of approximately 20 N/mm2 just 2 hours after the start of mixing. Adapting the open time to the [...]

Repair of taxiways with a slipform paver 2015, Vienna Airport (632)

2019-06-14T09:53:32+01:00

Initial situation In the parking areas at Vienna Airport the concrete paving had to be replaced on a surface with a width of approximately 7m and a length of approximately 30m. As the area was an important intersection, the closure periods had to be kept to a minimum. To carry out the construction process as quickly as possible the concrete was installed using a slipform paver. Solution and assessment For this project the rapid-hardening concrete Concretum® Q-FLASH 2/20 was used. It reaches a compressive strength of approximately 20 N/mm2 just 2 hours after the start of mixing. As the open [...]

Runway Repair at Basel Airport 2016, Basel Airport (920)

2019-06-14T09:53:33+01:00

Initial situation At Basel Airport the concrete paving at the start of the landing runway had to be replaced on a surface of approximately 70m2. Construction work had to be carried out at night to avoid disrupting normal flight operations. To allow the scheduled reopening of the runway the concrete had to reach an adequate strength at the time of acceptance - 5am. Solution and assessment For this project the rapid-hardening concrete Concretum® Q-FLASH 2/20 was used. It reaches a compressive strength of over 20 NN/mm2 just 2 hours after the start of mixing. This enabled construction work to be [...]

Repair works on runways and taxiways at Budapest Airport 2014, Hungary (822)

2019-06-14T09:53:34+01:00

  Initial situation With recurring need for repair works at Budapest Airport on takeoff and landing runways, as well as taxiways, repairs were made to various small and partial surfaces on existing concrete slabs. Solution and assessment The individual repair areas reported varying volumes, ranging from approximately 40 to a maximum of 850 litres. To address this situation, the rapid-hardening drymix mortar Concretum® Q-REP G was used for smaller places, up to a maximum excavated volume of 200 litres, whilst for all larger excavated volumes, rapid-hardening concrete Concretum® Q- FLASH 2/20 was used. The drymix mortar Concretum® Q-REP G [...]

Reconstruction of stand areas and taxiways at Barcelona Airport/ES (123)

2019-06-14T09:53:35+01:00

Initial situation At Barcelona airport, concrete slabs in the stand areas and taxiways were heavily damaged and needed to be reconstructed. High traffic volume during the day, meant that this reconstruction work was only possible in very short overnight time windows. Solution concept The rapid-hardening concrete, Concretum® Q-FLASH 2/20 reaches a compressive strength of > 20 N/mm2 just 2 hours after adding water and yet still remains workable for approx. 60 minutes. In addition, Concretum® Q-FLASH 2/20 has low shrinkage. As a result, cracks do not occur and the concrete is extremely durable. These qualities allowed the airport operator [...]
