In this study, possibility of top-down cracking in concrete pavement was investigated. The main cause of the crack is supposed to be tensile stress at the top of the concrete slab. 3DFEM simulations that took into account actual temperature distributions throughout slab depth were performed on concrete pavements for a...

In 2010 Houben has published a paper on the modelling of the process of cracking at transverse joints in jointed plain concrete pavements (JPCP). Houben uses equations from the standard Eurocode 2 for the time-dependent concrete properties and considers the thermal deformation and the shrinkage (drying and autogenous) for different...

The ability to spatially map the stiffness of the foundation layers under concrete pavements with intelligent compaction has created a need to define limits on the allowable stiffness variations in a given construction area as well as the maximum size of a non-complaint area which does not require remedial action....

This forum addressed design & construction related to Ports & Airports. The range of expert speakers included: Shane Dunstan - Roller Compacted Concrete Pavement Brian Shackel - Interlocking Block Paving Weeks White - Construction & Geotechnical John Knapton - Ports Robert Smith - Airports Bruce Rodway - Airports

In the construction of airport pavements, one possible way to save resources and lower construction costs is to reduce the slab thickness by introducing high-strength concrete. Cost-saving would be even more effective if the high-strength concrete could be laid without using any special materials or construction methods. To this end,...

Repair of concrete airstrips is a matter of particular interest. Besides being costly, it obstructs airport operations. Consequently, materials and construction procedures must comply with technical and operational demands. This article describes the development and application of a cementitious rapid hardening binder and a corresponding polymer fiber concrete for the...

The Dutch Federal Highway Administration introduced the project “Roads to the Future” in the year 2000. Amongst other innovations, the MODULAR ROAD, was one of the sub-projects. In a contest several parties in the roudbuilding business were asked to develop an idea for a modular type of road that had...

In the present study, alkali silica reactivity (ASR) in airfield runways (pavements) is reported based on investigation of two US airports. The study includes in-field detection of ASR distress features followed by detailed laboratory investigation of cores collected from strategic locations. This two-tire approach was found to be most effective...

In response to manage the increase in air traffic volume, Zurich International Airport has built a new Midfield Dock with apron and a new taxiway system. For the new operational surfaces, which lie in a reclaimed swamp area, a hard-wearing but economic pavement had to be built for aircraft weights...

During the extension to Zurich Airport in northern Switzerland, the ‘Oberbau’ Civil Engineering Construction Consortium (Arbeits-Gemeinschaft) has probably been successful in completing the largest volume of concrete laying works in Central Europe by comparison with similar conversion undertakings. The works included the preparation and laying down of concrete runways, taxiways...

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...
