Toulouse Airport - Rehabilitation of Runway 14L/32R: Technical - Economical and Environmental, Global Optimization

The Toulouse-Blagnac Airport is one of France's largest international airports. The scheduled traffic in 2006 was approximately 6 million passengers, a 2.7% increase compared to 2005. In order to cope with the increase in traffic as well as the upcoming arrival of heavier aircraft such as the Airbus A380, the Toulouse Airport ordered the renovation of runway 1 (14L/32R) which is usually used for commercial flights. This renovation was necessary in order to meet the security standards for surface characteristics, and to reinforce the load capacity of the runway. It involved laying a 0.07 m-thick layer of Aeronautic Asphalt Concrete on a 45 m-wide central strip, leaving the 7.5 m-wide lateral shoulders for a lighter, less-costly treatment (after the removal of daytime beaconing). The Toulouse reinforcement solution was defined using feedback from the experimental pavement carried out in 2001 on the taxiway W60, the goal of which was to validate reinforcement solutions for large aircraft carriers such as Airbus A380, A340-600 and Boeing B777. It aimed at keeping treated surfaces and overlay thickness to a minimum, for a saving of more than 50% of the normal cost. The project followed an optimised schedule, and is a perfect illustration of a new approach to conception in technical methods of pavement construction work. Firstly, this approach considers the environmental impact of different solutions. Secondly, it seeks the most economical solution possible. Thirdly it fully meets the client's technical requirements. The reinforcement solution retained is as follows. To overlay only the 45 m-wide central strip of the runway, which allows for the passage area of the landing gears of all aircrafts. To mill the diurnal beaconing marks to ensure excellent fixation on the entire existing pavement. To overlay a new 0.07 m-thick layer of Aeronautical Asphalt Concrete (AAC) to the 45 m-wide central strip. Partial environmental impact showed that the innovative technical solutions adopted for the Toulouse renovation generated excellent results for the environment. They also led to significant savings for the client. However, in order to validate the overall approach to this operation (optimizing technical, economical and environmental requirements), the performance of the overlaid structure of runway 14L/32R should be very carefully monitored.
