In 1996 a new pavement structure was launched in France under the name « Béton de Ciment Mince Collé (thin composite whitetopping) », BCMC. This technique was an adaptation of the Ultra Thin Whitetopping (UTW) developed in the USA since 1990. But while in the USA this technique was mainly...

For the last ten years, new composite pavement structures have raised a significant interest. Based on the association of a concrete layer bonded to an asphalt sub-base, they lead to a reduction of the layers thickness and cost. A long-lasting bond is essential. This paper focuses on the mechanical study...

Pavements on bridges are a very problematic element for each road administration. Classic European solution, concrete bridge deck with waterproofing membrane and pavement with asphalt wearing course, makes a lot of problems with maintenance, road closures etc. The paper presents results of research in the field of concrete pavements on...

Results of over one year monitoring concrete pavement slabs in São Paulo, where a typical hot-wet environment prevails, were presented. The experimental test tracks comprise 15 different concrete slabs instrumented with thermal resistors allowing the monitoring of temperatures. Over the course of the monitoring, it was sought the influence of...

As is the case in several European countries, Belgium is also constructing more and more roundabouts at busy intersections. They offer a better guarantee of a fluent, but at the same time safer, flow of traffic. The road surface of a roundabout is placed under a heavy load. In addition...

motorway network in Belgium is now nearly complete, a large share of current road investment is allocated to the renovation of the oldest concrete pavement. Some asphalt roads are also being replaced with concrete, sometimes via the complete reconstruction of the road structure, sometimes by an inlay (of the slow...

The technique of ultra-thin white topping, which has been used in the USA since the beginning of the 1990s, is characterised by a thickness of between 5 and 10 cm. They are characterised by a mesh of closely spaced joints in which the distance between the joints depends on the...

Roller concrete has been adopted from dam-building technology, where it is used as a rapidly constructed and durable solid concrete. In road construction, roller compacted concrete is predominantly used in foundations, as a supporting layer. For surfacing or as a layer of surfacing. Some applications in Belgium are discussed. This...

Between September and November 2002, an inlay in continuous reinforced concrete was constructed on the A10 motorway between Groot-Bijgaarden and Ternat. The main components of the section of road are concrete slabs that are overlaid with asphalt surfacing. The work was performed in the shortest possible period, during which the...

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...

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...

This paper present the good possibilities that we can expect with exposed aggregate concrete surfaces
