Spain can boast of having a very large concrete pavement area, amounting to more than 90 percent in over 35 civil airfields and 5 military air bases. Technical details, construction methods and performance of these pavements are analysed, together with their evolution in the latest projects which have started in...
Investigation on Thermal Stress and Prestress of a 151 m Prestressed Concrete Pavement
Few prestressed concrete pavements of more than 100 m length have been constructed in order to avoid the development of cracking at early ages as well as to get design prestress. It the prestressed concrete slab is paved as long as possible, the construction period is shorter and the cost...
Recent Innovations in the Construction of Concrete Pavements on the Brussels National Airport
At the Brussels National Airport, important expansion works, mainly new taxi-lanes and platforms have been underway since 1989 in accordance with the masterplan "Zaventem 2000". For the new platforms, almost 500.000 m 2 will be paved with a 35 cm thick high quality concrete pavement. By the end of 1993,...
Concrete Overlay Thickness Design Based on FWD Deflections for Airports
Since the overlay thickness must be decided considerinq the structural condition of the existing pavement, FWD was introduced to evaluate the mechanical properties and to obtain input data for the overlay design. In the case of concrete overlays for concrete pavements, the overlay thickness depends on the existing slab thickness...
Concrete Slab Tracks for Railways
Due to the planning and construction of new high speed railways, the development and testing of the ballastless tracks, which started in Germany in the seventies, is now turning up again. The use of this almost mairitenailce free structure requires the assessment of the multi-layer system. For the slab track...
Concrete Airport Areas Results of Recent Achievements
Owing to its anti-kerosene properties, its resistance to heat and punching, concrete is always used in the tarmac of the runway threshold of military airports and in the aprons of large-sized aircrafts in civil airports. Due to the strong competition with flexible structures, concrete is at disadvantage as far as...
The Use of Non Destructive Testing and Backcalculation of Moduli in the Rehabilitation Project of the Runway of the Otopeni Airport at Bucarest (Romania)
Results of a rehabilitation project for the runway nr.1 of the Otopeni Airport at Bucarest by using the Falling Weight Deflectometer (FWD). The paper describes how the deflection basin produced by the FWD can be used to characterize the pavement behaviour and to backcalculate the Young modulus (E) of the...
Temperature Effects on the Concrete Pavement of the Marco Polo Airport of Venice
This paper examines the results of temperature and strain measurements obtained using strain gauges installed in the concrete pavement of the aircraft parking area of the "Marco Polo" international airport of Venice. The purpose was to control the design assumptions and models and to assess the long term behaviour of...
New Standards in the Construction of Aircraft Movement Areas
Airport runways and other aircraft movement areas are among today's most important infrastructure elements. The paper gives an introduction to general aspects of design and construction of concrete airport pavements, emphasizing the advantages of the two-course "wet on wet" placement technique. The above mentioned aspects are illustrated by the description...
Accelerated Wear Testing of High Strength Concrete in Norway
To give guidelines for the mix design on high performance concrete with high wear resistance, and to study wear of high strength concrete, the Norwegian cement producer NORCEM operates a test rig specially developed for this purpose. The tests show concrete to give 2-3 times the wear resistance of asphalt....
The Significance of Grain Size Distribution for the Behaviour of High Strength Concrete for Road Purposes
In the last years high strength concrete has been used more and more frequently for road construction in Norway. To obtain good abrasion properties and a good wurkaL,ility the quality of the coorco oggrogateE and the ovrall grain qi7 ,9 distribution is very important. By improving the abrasion properties it...
Status of a Five Year Old 170 mm Thick Jointed High Strength Concrete Pavement in Norway
The current pavement is a 8.6 km long part of the main highway North of Oslo. The concrete has a characteristic cube strength of 90MPa and the slab thickness is 170 mm. The subbase mainly consists of local natural sand and gravel. The general condition of the pavement is rather...
