Jointless Pavements for Heavy-Duty Airport Application: The Semi-Flexible Approach
In Copenhagen Airport, extensive developments in the field of Semi-Flexible pavement structures have demonstrated high potentials for very heavy loads and static loads in particular. The experience of the Semi-Flexible Pavement (SFP) concept dates back 25 years. However, during the late eighties, a new generation of this special product emerged which brought about further development towards high quality pavements exhibiting very high strength and durability. Today, it is possible to design Semi-Flexible Pavements for type E aircrafts in regard of aprons, stand gates, de-icing stands, start-up pads, taxiways and other heavy loaded areas. More than 300,000m2 has been applied in Copenhagen Airport. Of this area, 165,000m2 are constructed from 1988 through 2000 utilizing the enhanced second generation technique. The general SFP concept consists of a joint less wearing course composed of an open-graded asphalt concrete filled with a special slurry grout. The underlying bituminous layers are designed for high strength and high load-bearing capacity. The Semi-Flexible wearing course will not develop cracks due to shrinkage, nor will it show any plastic flow. The joint less SFP have provided Copenhagen Airport with a high performing pavement with a minimum of maintenance. The better economy and advantageous technology offered by the SFP have been desirable compared to concrete slab pavements. The new enhanced Heavy-Duty Semi-Flexible Pavement structures are expected to be the desired solution for pavements designed for heavy loads.
