1 [Fascinating Projects] Yas Marina Circuit Abu Dhabi E

2 2 The Emirate of Abu Dhabi has around million inhabitants of which approximately 80% are immigrant workers. The city of Abu Dhabi is by far the largest city in the Emirate. Abu Dhabi City is situated on a 70 km² island in the mangrove belt, which is connected to the mainland by the Mussafa and al-maqtaa Bridge. The main island is surrounded by some artificially extended or newly dredged up islands which are only partly developed at present. C Abu Dhabi Centuries old Arab traditions collide The Arab motifs that decorate many with modern Western culture in this of the architecturally striking tall boom town.

3 4 5 Megaprojekt YAS ISLAND The new Grand Prix track is part of a gigantic 40 billion dollar project with the aim of establishing Abu Dhabi as a holiday paradise. A Ferrari Park with its own museum and theatre and also a dragster track, a driving school, go-kart tracks, dune tracks, three golf courses, several 5 star hotels, gigantic shopping centres, restaurants and luxury properties are being built alongside the race track on the 2500 ha natural island of Yas. TheYas Marina Circuit New highlight in the race calender: Plenty of sun The Yas Marina Circuit is the first race track worldwide where all stands are covered. Not only up to 50,000 spectators but also teams and media representatives can follow the fast cars in their battle for victory from seats in the shade. VIPs have the best view: they can sit on top of the 60 m high Sun Tower with a view of the whole track. Legend: 6 New motor sport highlight: The Yas Marina Circuit Racing is booming in Asia and Arabia. This is reason enough for building new race tracks to high quality criteria to satisfy the requirements of modern motor sport. Another ultra modern grand prix track was completed in autumn 2009 after Malaysia, China, Bahrain and Turkey Start/Finish Main Grandstand Pit-Building Yas Marina Hotel Sun-Tower Yacht Club The new track was built in accordance with plans by the internationally renowned German race track architect, Hermann Tilke, and cuts through the centre of Yas Island and then over a high-speed section and a stretch along the marina with a backdrop which gives you the feeling of being in Monaco right in the middle of the desert. On other sections there are numerous bends providing plenty of excitement with overtaking manoeuvres. 7 8 Driving School Building Dragster Track 8 7 The design of the 5.5 km track with a total of 20 bends is extremely versatile. The layout provides a mix of fast and slow bends. A maximum speed of 320 km/h is possible on the long straight sections. The highlight is certainly the section round the marina with the drive through the hotel.

4 6 7 Compactors do basic work An essential prerequisite for a perfect asphalt surface course is a level and well compacted roadbed. To get the quality right, the construction companies in Abu Dhabi opted for HAMM quality when creating the roadbed and the courses of crushed stone. The first HAMM rollers were deployed to compact the roadbed right at the start of the project. A formation level made of broken material and sand with an impressive expanse of 1.2 million m² was created. Then the team from Bickhardt Bau AG, general contractors for road construction works, processed around 2 million tonnes of broken stones into an unbound base course in the next few months. The course levelled by graders acquired the necessary stability through the compacting strength of HAMM compactors. Perfect roadbed for dragsters In future, not only fans of classical racing will get their money s worth in Abu Dhabi. The hearts of dragster fans will also beat faster. An almost seamless acceleration section on specially produced reinforced concrete has been built on this peninsular in the Persian Gulf. Large-volume engines with several thousand HP can step up the pace here because truly hot sets of wheels can accelerate optimally on the perfectly level concrete road surface. There was no doubt: Bickhardt Bau used HAMM VIO compactors to compact the formation level. Dragster racing, a highly explosive mix of speed, sport and show, is attracting more and more fans into motor sport arenas all around the globe. Two HP giants wait for the starting signal in each case. Then they go from nought to one hundred in less than one second. And after a quarter of mile it comes to an end. Whoever had the greater acceleration and the better reaction capacity is the winner of the duel.

5 8 Maschines from the WIRTGEN Group for the requisite quality 9 Te a mw o r k Team w or k The high-speed drives of the aerodynamically optimised Formula 1 cars place maximum demands on the grip and the evenness of the asphalt surface. On the other hand, tolerances for the special asphalt paving were minimal. Therefore, there were no compromises with the engineering. Bickhardt Bau chose the best: Vögele finishers and HAMM rollers. Seven new HD series tandem rollers, one Compact Line tandem roller and one rubberwheeled roller were shipped from Germany to the Persian Gulf in May Their first job was to pave the base and binder Specialists continuously monitored asphalt There was great excitement when the courses on the race track with escape areas, production in the mixing plant. The roller asphalt surface course was paved at the paddock and emergency routes as well as all drivers simultaneously compacted the high- beginning of August.

Vögele finishers and seven HAMM rollers of asphalt from 210,000 tonnes of asphalt in went through their paces for five whole total in Abu Dhabi. nights under the race track floodlights. Six to seven passes in hot-on-hot paving were sufficient for compacting and sealing partly with oscillation, partly statically - until the stringent quality requirements were met. The asphalt specialists always placed the transition points between each day s sections in an acceleration zone. This avoids cracks which could arise in the braking areas at a later date due to enormous forces.
