This paper describes a new design of joints in rigid pavement, in this case the angle between joints will be 120 grades in anypoint of the pavement between edges. This new concept about corners angle,change the original work of Westergaard for the "corner load",because it only considerate angles with 90...

In order to harmonize FWD condition surveys on concretee pavements in the Netherlands, CROW's committee UEC1 has developed an structural evaluation procedure for jointed concrete airfield pavements. The committee has developed procedures for in-situ testing and models for determining of the mechanical pavement properties based on FWD measurements. With respect...

The pavement of the apron on Brussels National Airport, which was constructed in the early sixties, was forming cracks. Given that fragments of concrete could in time be a danger to the aircraft engines, a thorough renovation of the apron was imperative. The distinctive feature of the site is that...

This paper describes a method for routinely evaluating airfield pavement surface roughness from an aircraft ride quality perspective. The method is designed to be as compatible as practical with existing pavement management system data collection and reporting processes. Ride quality has always been recognized as a major factor in a...

This report details the reconstruction of 12,500 m 2 of 7.5*7.5*0.4m concrete slabs on the Madrid-Barajas airpoi't apron, using high performance and rapid setting concrete (HPRSC). HPRSC is an ideal concrete for this type of repairs, given that within six hours of placing the slab is able to bear its...

The air operation in Ushuaia is of such difficulty that landing in the runway of the old Sea and air Base at Ushuaia was considered quite a challenge by the pilots that operated there. Several accidents occurred, amongst them one that destroyed a Boeing B-737 and another in which a...

A New Geometry of Airport Concrete Pavements

The highest expression of engineering lies in those works which challenge nature and rise through a modified environment as a proof of human genius and perseverance. Ushuaia's new international is one of those titanic works, located in the Andean geography, next to the Beagle Channel, in the most southern city...

This paper describes design solutions of the concrete pavements from Macau International Airport, including runway, taxiways and apron. Aspects about the execution and results from quality control are also presented, within the scope of activities made by LECM (Macau Civil Engineering Laboratory) in this project, as a quality assurance agent...

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...

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...

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,...
