The Use of Non Destructive Testing and Backcalculation of Moduli in the Rehabilitation Project of the Runway of the Otopeni Airport at Bucarest (Romania)

Conf-paper-iscr

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...

Concrete Airport Areas Results of Recent Achievements

Conf-paper-iscr

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...

Concrete Overlay Thickness Design Based on FWD Deflections for Airports

Conf-paper-iscr

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...

Recent Innovations in the Construction of Concrete Pavements on the Brussels National Airport

Conf-paper-iscr

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,...

Spanish Experience with Concrete Pavements for Airports

Conf-paper-iscr

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...

Application of Newly Developed Prestressed Concrete Pavement Technology in Japanese Airports

Conf-paper-iscr

Many researches on prestressed concrete (PC) pavements have been conducted. The applicability of a class Ill PC slab, in which cracking at the bottom of the slab is permitted, was confirmed for airport pavements. A new type of PC precast slab pavement with new jointing systems was developed. A new...

Setting New Standards in the Construction of Flight Operation Areas in MUC 2

Conf-paper-iscr

The construction of the International Airport MUC 2 and especiallyof the flight operation areas in -for road designers- gigantic dimensions and short time-limit was a unique chance for the ex-perts to search for and find newstandards for tech-nique, economy and quality by an innovative fur-ther development of proven equipment and...

Rapid Reconstruction of Concrete Slabs on Airfield Runways

Conf-paper-iscr

The rapid reconstruction of concrete slabs on airfield runways is a technology presented to airports operation authorities in order to strictly shorten the reparation period when the runway is unpracticable. The French airports and airbases engineering services proceeded with two demonstration works on the BORDEAUX and NlMES airports. The reconstruction...
