CRCP

Continuously reinforced concrete pavement (CRCP) structures are becoming more popular for high quality transport purposes and long lasting pavement solutions in The Netherlands. This increase raised the demand for practical guidelines, recommendations and standardisation with respect to design, construction details, the preparation of tender documents and construction. Up to now...

Continuously reinforced concrete pavements (CRCPs), when proper design and construction guidelines are followed, may allow more than thirty million equivalent single axle load application as observed at existing CRCP sections in the United States of America. Otherwise, the CRCP may prematurely fail and require costly maintenance earlier than anticipated. In...

and safety levels for very many years. The Ministry of Transport, Infrastructure and Facilities of the Walloon Region conducted a comparative study of the motorway in 2000 between a continuously reinforced concrete pavement and a bituminous pavement. Very many factors obviously come into play for an objective comparison and they...

Durability, the absence of deformations and a low level of maintenance when the road structure has been correctly designed and implemented are the features which are generally unanimously approved as regards the qualities of cement concrete surfacing. In contrast, comfort and driving noise are the characteristics which lead to the...

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...

Continuously Reinforced Concrete (CRC), invented in the United-States in 1921, has been developing in France since 1983, in the following contexts: - New constructions (50 km of motorway) The structures chosen are alternately: • CRC + lean concrete • CRC + bituminous concrete + stabilized capping layer - Strengthening of...

The section of the A6a motorway between Porte d'Orléans in Paris and the Wissous interchange (10 km to the sniith) wRr npened in April 1960 For 34 years, the carriageways of this motorway, which have had to stand "double TO" traffic (4000 heavy loads a day), and which consist of...

Since 1975, the year in which the first continuous concrete plant was introduced for a road construction project, the use of a continuous production process has become more widespread, and even generalized, in France. Applications in other European countries have started to appear, yet do remain in the nascent stages....

Continuous reinforced concrete (CRC) pavements built in France since this technique was first used in 1983 have pratically all been designed in the same way as pavements consisting of dowelled slabs. Owing to the circular form of the test tracks at fatigue facility of the Laboratoire Central des Ponts et...

The ROLLFIBER process consists of roller-compacted cement concrete reinforced with steel fibers. It enables you to build continuous pavements without any joints. To reach this level of performance, the fiber has to have what is known as total' anchorage, and its action is optimized by the use of a concrete...

It seems now in France that, after these experiences and their results, the idea to accept for CRCP, a bonding assumption on a bituminous support, is really and that CRCP technology can hope now a new positive future.

The work was undertaken by contractors Ooms Avenhorn. Work took place in the months of July, August, September and October 1995. The roundabout was opened for traffic on 6I October 1995 (photo 6). More than two years after opening of the roundabout and the road metalling associated with it, it...
