The Most Powerful Ground Crew in Asia
The first plane to land at the new Yogyakarta International Airport (YIA) on the Indonesian island of Java, in Indonesia, was an A320 from Jakarta. Eleven slipform pavers from WIRTGEN played a key role in the airport’s construction. Once the YIA project has been completed, up to 20 million passengers will be able to take off and land there each year. With a current terminal area of 130,000 m2, the new airport is set to replace Adisutjipto Airport (JOG), which is struggling with capacity issues.
The tight schedule was a particular challenge of the large-scale project in Yogyakarta. Reliable solutions from one source were required if the concrete slabs were to be completed on time. And this is precisely what the Wirtgen Group sales and service company in Singapore promptly delivered, working in collaboration with the Indonesian Wirtgen Group dealer PT Gaya Makmur Tractors. This included the large fleet of machines required, but also technical support and on-site application consulting.
A team of 4 SP 64 machines, 6 SP 500 machines, and a SP 84i machine formed the final lineup for the high-precision, cost-effective paving of the 3,250 m-long, 45 m-wide runway, its taxiways, and the apron.
The 50 cm-thick concrete layer was paved across a width of 2 m, 5 m, or 6 m, depending on the area involved. During the process, dowels, which were prepositioned on reinforcement cages spaced at transverse intervals of 30 cm, and a wire grid were integrated in the concrete as additional reinforcements.
The airport is set to grow by another 65,000 m2 during the second phase of construction. The landing runway will also be extended by another 350 m.
Wirtgen is the ideal technology and quality partner for airport construction, whatever the specifications or location involved. A seamless product range, the expertise of experienced applications experts, and reliable service throughout the world are key in this respect. Boasting a wide variety of applications, slipform pavers can tackle highly diverse requirements on the jobsite – anywhere in the world. For instance, they can easily produce concrete surfaces with a high degree of precision without using the fixed steel molds so often utilized at airports.
