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...

ratios between 1.0 and 1.25 to achieve the proper performance of the slabs designed. It is clear that thickness of slabs has to be properly designed according to the operations foreseen for the term of use. In the case of rehabilitations by way of overlapped layer, this has rendered a...

In the quest for introducing materials and techniques of construction, the Research & Development Division of the Road Development Authority, Sri Lanka has carried out several trials and successfully constructed an airport apron, a causeway of 2km length using Roller Compacted Concrete (RCC) pavements and a road of length 0.265km....

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 use of CD 40-A cement eliminates the classical procedures of measuring plastifying and air entraining additives at the preparation on site of the road concrete. The article presents the main characteristics of CD 40-A and the results of laboratory tests carried out to establish the influence of this type...

The problem of using fine-grained (sand) concrete instead of the "classic one in the construction of road and airfield pavements is analysed. In sand concrete the coarse aggregate, crushed stone or gravel, are substituted by natural sand or a blend of natural sand and screenings 0.5 (10) mm. The use...

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...
