SubscribeCopenhagen Airport is, with its annual 17 million passengers, 380,000 tonnes freight and direct connections to more than 125 airports worldwide, the major airport in Northern Europe. The airport is furthermore the primary airport for SAS airlines, a member of the Star alliance, and also for the air freight company DHL.

The airport comprises an area of 12.4 square kilometres, and has three runways, three passenger terminals and 114 aprons. In accordance with the general increase in air traffic, the airport undergoes constant expansion.
Thus the airport has planned investments of more than USD 1 billion over a ten-year period, which includes a new terminal and associated aprons.
Densit a/s has performed over 150,000 m2 pavement work for the airport since 1988, both in new build and renovation projects, which have included de-icer areas, cargo centers, a contaminated earth depot and hangars. The largest projects have however been aprons.
The most recent apron construction was in 1998-99, when Densit a/s was involved in the construction of four new aprons totalling 21,000 square metres, in association with a new terminal.

The aprons are designed to withstand category C aircraft and have the following pavement design:
Copenhagen Airport chose Densiphalt® as the optimal pavement type for aprons based on comparative testing and analysis of a variety of pavements performed in 1996. The comparison of pavements included inspection of airport pavements world wide, followed by a technical investigation of eight selected pavement types, including different forms of asphalt, concrete slabs, concrete blocks and Densiphalt®. The investigators calculated comparative construction and maintenance costs for the pavements over a 20-year period.
The calculations showed clearly that Densiphalt® was the cheapest solution in terms of overall capital and operating costs, with a net present value of only 60% of that of concrete slabs. Densiphalt® was therefore the natural choice for Copenhagen Airport.

During 1999 - 2000 Copenhagen Airport has constructed 50,000 square metres of new aprons for the category F aircraft B 747. The aprons are designed according to the following pavement design:
The aprons for the B 747’s differ significantly from the existing Densiphalt® aprons as the wearing course is twice as thick. The application of the wearing course was also slightly different as the asphalt was applied twice, in layers of 50 mm, instead of the usual one layer. This was necessary in order to meet the tolerance requirements regarding the evenness of the apron. The Densiphalt® mortar was applied without vibration as a normal one-step procedure.
With the possibility of varying the thickness of the wearing course to meet the demands of the various aircraft, Densiphalt® shows once again it’s flexibility and strength, both in use as well as installation.
