CRCP

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...

Few prestressed concrete pavements of more than 100 m length have been constructed in order to avoid the development of cracking at early ages as well as to get design prestress. It the prestressed concrete slab is paved as long as possible, the construction period is shorter and the cost...

Most of the Belgian Motorways, with a concrete pavement, have a deeply grooved concrete surface. Although those wearing courses have a very good skid resistance, there is a great concern about the noise pollution. Not only noise barriers and the porous asphalt overlay, but recently also the grinding are an...

rFor the reconstruction of the E31 3 motorway which was constructed with concrete slabs round about 1960, CRCP was chosen and since 1983 the exposed aggregate technique was applied there. As the conventional exposed aggregate concrete is still too noisy, in 1992 it was decided to pursue the reconstruction works...

Short description of the rehabilitation works on the most heavily trafficked motorway in Belgium.

C.R.C.P. Technology has been selected by SAPRR in France foz its overlay programme on the heavy traffic Highway A6 Paris/Lyon. This programme started in 1983 with deformed bars Fe E500 with a steellconcrete section ratio 0,67%. Considering the logistic and safety problems on

The continuously-reinforced semi-rigid structure consists basically of a thick structural layer placed directly on the foundation when it is made of untreated, permeable materials, or on a draining layer of geotextile when it is treated. This layer is made of concrete having a low cement content and cracking is rnntrnlled...
