The pavement management of concrete roads in Ge rmany is essentially based on surface-referred status datas. Suitable measuring techniques are available for the data aquisition. Approved and practicable methods apply for their evaluation. However there are no appropriate procedures and concepts for the structural substance evaluation regarding the prognosis of...
the Influence of the Curing Method on Early Cracking Risk During Hot Weather Paving
Concrete pavements which are placed during hot summer weather conditions, harden on the top side, due to the solar radiation, at higher temperatures, as is the case for the bottom side. As soon as the concrete cools down at the top side during the first night, the concrete pavement tends...
Renewal of Concrete Slabs Using High Performance Concrete
The considerable increase of road traffic all over the world increases the demand for traffic surfaces with a longer lifespan and less repairs. When doing maintenance and repair works it is very important to keep short construction times in order to reduce obstruction to traffic to meet this challenge. A...
New Economical Structures Made of Thin Composite Whitetopping
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...
Fatigue Test and Mechanical Study of Adhesion Between Concrete and Asphalt
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...
Concrete Pavements on Bridges
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...
Temperature Differential in Concrete Pavements in Tropical Environment
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...
Concrete Roundabouts
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...
Sustainable Road Building with Low-Noise Crcp on Belgian Motorways
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...
Experimental Sections of Ultra-Thin White Topping in Tournai
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 Compacted Concrete
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...
Inlay in Continuous Reinforced Concrete on the A10 Brussels – Oostende at Ternat
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...
