Amsterdam Lelystad Airport NL

After years of preparation for an expansion of Schiphol Airport, an expansion of the existing Lelystad Airport has finally been decided. The history of Lelystad Airport starts with the draining of the Flevopolder. Airplanes were needed and various grass tracks were laid out. These jobs were not efficient enough in the long run and in the year 1973 plans were made for a paved track. At that time, this airport officially became Lelystad Airport. The intended business function of Lelystad Airport was not achieved, despite an extended runway and takeover by Schiphol Group from Amsterdam.

soil stabilization as a sustainable alternative

The last expansion in 2018 of Lelystad Airport has taken shape in recent years. After preparatory engineering and tendering, the company Dura Vermeer Infra BV was awarded this project. They build the new runway, taxiways and stabling sites. The terminal and surrounding parking spaces are also at the expense of contractor Dura Vermeer. In close collaboration with Terrastab, a design has been drawn up by our engineering office based on the use of primary raw materials on site. The naturally present clay soil is stabilized with a hydraulic binder so that this soil layer does not need to be excavated and can therefore simply remain seated. This saves enormous (transport) costs and there is much less inconvenience for the environment.

By geotechnical research of the composition of the existing materials in combination with the right amount and type of binder, the old Zuiderzee floor on which this new airport is located, will be given the same or a higher value as with a traditional sand build.

SAVING WITH SOIL STABILIZATION

Despite the supply of the materials that Terrastab adds (about 5% (weight) share of the package), we have a considerable cost reduction with also a CO₂ reduction and we have saved time. Traditionally the structure had to consist of a meter of new sand to be applied of about 1 meter. This layer has been saved by treating the existing basis and delivering it in the same quality as the traditional construction. Click here for the project brochure.
