CRCP

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...

In the Netherlands Rijkswaterstaat is the authority in charge among others of the construction of highways. The department Utrecht of Rijkswaterstaat has chosen a continuously reinforced concrete roadbase for the construction of the 7 km long new highway scction between the cities of Bunnik and I Jtrecht. This choise was...

The experimental continuously reinforced concrete (C. R. C. P.) road section has been realized in 1975 on a Romanian principal road, in a mountain area. There are presented the design method, the materials, the technology and the behavior after twenty years of traffic.

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...

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...
