This paper describes a structural design method developed for composite pavement which is composed of an asphalt surface course (ASC) and a continuously reinforced concrete base course (CRCB). The design method is based on the fatigue analysis of CRCB. In the analysis, loading and thermal stresses in (2RU13 are calculated...
A Design Method of Composite Pavement with Asphalt Surface Course and Continuously Reinforced Concrete Base Course
Application of High Performance Concretes in Highway and Traflic Infrastructure Construction
High performance concrete - HPC - is characterised by high strength and considerable durability under high service load. In highway construction these concrete is used to constructing and very rapid repairs of pavements, bridges, viaducts and tunnels. Differentiation in types of such objects as well as erection conditions and than...
Performance of the Ecopave System After Five Years Trafficking
ECOPAVE is a system of laying concrete through a modified bituminous paver, inducing transverse cracks into the concrete, and overlaying with a thin bituminous surfacing. The system has been developed through a BRITE project with partners in the UK and Denmark. It is coiisideied to provide economic benefits over the...
Monitoring Program for a Continuously Reinforced Concrete Roadbase in the E35 Highway in the Netherlands
On the European route E35 near Utrecht in the Netherlands a new highway section has been built. The authority in charge has chosen a continuously reinforced concrete roadbase. A monitoring program has been started to collect data from the pavement behaviour. The data will be used fnr rnmparing the chosen...
Surface Characteristics of Two Recently Constructed Trunk Roads in the UK
In an effort to tackle road traffic noise, research into quieter road surfaces has included trials of a new type of concrete surfacing called exposed aggregate concrete, which has been used in a number of other European countries. Two trials of exposed aggregate concrete have been constructed in the UK;...
Roughness Condition and Rule Quality of Bicycle Lanes
The Netherlands are a flat country, where the bicycle is a good alternative for short and midrange transportation. The government tries to encourage the use of a bicycle by improving the bicycle infrastructure, thus trying to reduce movements by car. Bicycle pavements are managed at a local or county level....
Urban Rigid Pavements in Italy
Since the end of the Second World War many of the urban road pavements that had been executed in concrete have been gradually repaved with bitumen. As a result of the problems induced by increasing traffic rates, rigid pavements are now gaining new impetus also within urban road networks. PIARC's...
Fatigue Properties of Plain Concrete
Based on a literature search, several types of fatigue relationships were collected, compared and analysed for plain concrete (specimens, pavements) subjected to repeated loading. A uniform fatigue relation - based on the FS- R concept - has been proposed for the flexural tensile strength. The 50%-probability curves have been analytically...
Spanish Experience in Concrete Pavements on Bridges
There are more than one hundred and sixty bridges with concrete pavement in Spain. All of them are in motorways with heavy traffic but in very different thermal regions. Three types of bridge concrete pavements are used: monolithic, bonded and unbonded. This paper presents the Spanish experience in concrete pavements...
Mechanistic Evaluation of Spalling Distress
In this paper, delamination formation is investigated. Stresses due to temperature and moisture variation are considered within the scope of the formation of the delamination. Tensile and shear stresses are determined numerically based on finite element analysis using simulated pavement moisture data. A finite element program is developed to allow...
A Comparison of Life Cycle Costs of Asphalt and Concrete Pavements by Computer Modelling
In the beginning of the 1990s the coiiciete industry tried to introduce newly developed concrete pavements on the Danish market, which is dominated by asphalt pavements. A number of rough estimates were carried out by all the involved parts, showing completely different results. In this paper a non-biased intensive study...
Concrete Safety Barriers and Coming European Standards
For the year-long approved concrete safety barriers, produced of in-situ concrete or prefabricated units, the new EN 1317 part 1 will discribe the general criterions of the test methods in the future, and part 2 the performance classes and acceptance criteriOns. The opening of the European Market has consequences for...
