As it is well known, in Belgium since the stast of the 1970s, continuously reinforced concrete has to a large extent been used as concrete pavement for motorways. On the bridges, asphalt was sometimes applied, which made it necessary to use expensive anchorages on both sides of the bridges to...
Overlaying and Behavior of Lorient-Lann Bihone Main Runway with Continuously Reinforced Concrete (CRC)
The main runway of Lorient-Lann Bihoud airport was overlayed with continuously reinforced concrete in 1989. This operation is examplary because from the technical viewpoint it is still today the only one in Europe. This runway is used now for eight years by civil and military traffic. The cracking development is...
Experience with Rehabilitation and Reconstruction of Old Concrete Motorways In Austria
The 300 km Al Westautobahn between Vienna and Salzburg has reached an age of between 30 to 40 years. 10 years ago, systematic reconstruction of the concrete pavement was initiated. To date, 180 km of carriageway, i.e. 31%, have been completed. Initially, the new asphalt or concrete structure was mostly...
Multifunction Concrete Roadways Potericitls in Urban Areas
Combating noise, disturbances and safety hazards on transport infrastructures is one of the leading preoccupations indicated by 85 % of city dwellers in industrialised countries. The road concrete industry has fully realised this real challenge for durable building and maintenance of concrete roads capable of controlling disturbances caused by urban...
Swedish Concrete Block Pavements Investigation of State and Performance
Concrete block pavements have a good load carrying capacity and load distribution ability. The concrete block pavement is durable, insensitive to settlements, easy to repair, bright, and aesthetically attractive. It has therefore frequently been used in urban environments. In Sweden, however, concrete block pavements have been less frequent than in...
Consideration of Some Factors Affecting the Competitiveness and Potential for Future Use of Concrete Roads in the UK
Although concrete roads have traditionally been used in the construction of a small part of the UK network, there is continuing interest in the potential for concrete pavements. Consideration of the way in which whole life cost (WLC) may influence selection of the most competitive form of concrete structure when...
A Contribution to Concrete Pavement Analysis
The concrete pavement structure consisting of the M40 concrete slab 160 to 240 mm in thickness and the cement-stabilized base course (CSB) 150 to 250 mm in thickness, is analyzed in the paper. The pavement slab is not reinforced and the spacing between expansion joints was selected in such a...
The Use of Slipform Technique for Traffic Infrastructure Constructions
Slipform technique can be used for construction of concrete pavements for roads, but also for construction of aircraft movement areas, industrial surfaces, secondary traffic areas, and rigid railtrack systems made of conciele. Slipform technique can be used for construction of concrete safety barriers, cable troughs, curbs or gutters, too. If...
Study of Rigid Pavement with Puzzolanic Over Sulfated Binders
The paper presents the employed materials, including binder (Romanian patent) for the technology of mixing and laying of reinforcement concrete for an existing flexible pavement. After thirteen years of significant traffic (over 1.2 millions 100 kN axles) the pavement behavior is correct, proved by the state of slab margins and...
Influence of Fly Ash on Abrasion Resistance of Concrete for Roads Pavements
In Portugal, fly ash is often used as a cement replacement material on concrete for road pavements. The percentages of replacement generally range from about 30% in the top pavement layer up to 50% in the bottom layer. A study was carried out for evaluating to what extent such amounts...
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...
Concrete Pavements for Heavy Traffic Areas
The space available on our roads is becoming less and less. All forecasts agree that the increase in traffic will also cotiliiiue to grow considerably in the years before us. At the same time, because of the changes in political conditions in Europe and the opening of the frontiers, there...
