The paper presents the analysis of the numerical model of airport slab and foundation under thermal loading. Various types of constrain (unilateral and bilateral) between slab and foundation have been taken into consideration. Numerical data has been compared with experimental results, concerning vertical displacements of airfield plate subjected to the...
Reclaimed Porous Asphalt Pavement Used as Aggregate in Cement Bound Concrete Pavement
In the Netherlands reclaimed asphalt pavement is normally used as cold aggregate to produce recycled hot asphalt mixtures. However reclaimed asphalt pavement originating from porous asphalt pavement can not be used in this process. Therefore it would be valuable if these residual aggregates could be used in concrete production. A...
Rapid Hardening Fiber Concrete for Airport Pavement Repair
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...
Guidelines for the Design and Construction of Kerb-Guided Busway Infrastructure in the UK
The Guided Busway Design Handbook, produced in 2004 and the Guided Busway Construction Handbook (2006) are best practice guides to guideway construction. This paper describes development of the handbooks which drew on experience from across industry and lessons learnt from previous projects. Ongoing work since publication of the handbooks to...
Design Philosophy of a Concrete Bone Roundabout (CBR)
The Netherlands has made a clear decision to increase traffic mobility by reducing the use of traffic lights wherever possible. If traffic lights are not to be used, crossings need to be changed. The easiest solution is to change crossings into roundabouts and this solution (depending of the volume of...
New Technique for Silencing Existing Concrete Roads
Some concrete roads have been constructed and finished or textured that lead to an unfavourable texture. This kind of textures can lead to unacceptable high noise levels. However, from the civilengineering point of view these roads can be very durable. In those cases, only the surface needs a treatment to...
Prestressed Concrete Pavements
In this paper the results of laboratory investigation preceding realization of continuous prestressed concrete pavement at Krakow Balice Airport are presented. Three concrete slabs of dimentions 1.0 m × 3.6 m × 0.16 m were realized in the Laboratory of Technological University of Krakow. Two of them were prestressed...
Decision Support Model for Road Pavements Based on Whole Life Costing, Life Cycle Analysis and Multi-Criteria Analysis
In response to the growing importance of sustainable building, designers, consultants and pavement managers now tend to make more rational decisions than before when comparing the pros and cons of the construction, maintenance and management of various types of road pavements. Asphalt and concrete pavements offer specific advantages that need...
Design Methods for Cement Bound Bases in Pavement Structures
Application of bound foundation materials is attractive and allows to reduce the required asphalt thickness due to the high stiffness of the cement bound material. Unfortunately, the design of a pavement with a bound base is not standard. This hampers the application of cemented waste materials in road bases. This...
Performance of Whitetopping in Florida
Since 1988, the Florida Department of Transportation (FDOT) has been monitoring the performance of the first experimental Whitetopping project in Florida for possible implementation as an option for rehabilitation of rutted and cracked asphalt pavements. The project includes three major sections with thicknesses of 150 mm (6 in.), 175 mm...
Continuously Reinforced Concrete Pavement for Combined Tram – Busway in Gent, Belgium
The project concerns the design and supervision of construction for the realisation of a new combined tramway and bus lane linking the main railway station of Gent (Belgium) with the exhibition halls at Flanders Expo. Fundamental criteria for the design included the durability of the pavement, a pleasing appearance compatible...
Maintenance and Comparison of Asphalt and Concrete Parts of Motorways in the Czech Republic
For a long time the professional community in the Czech Republic have been criticizing the fact, that construction, maintenance and rehabilitation of motorways are not systematically studied in light of technology, functionality and reliability in connection with economy of these processes. Therefore the authors of this paper began an R&D...
