CRCP

From the point of view of construction performances concrete qualities are well known, durability, high elasticity modulus and workability, for instance, stand for them among many others. But it is also well known that unfortunately, not all of its properties are on the positive side. Cracking, by a variety of...

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...

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...

Roundabouts have already been used in Belgium for several years to regulate traffic at major road intersections. The surfaces at roundabouts are particularly subject to tangential stresses that result from centrifugal forces and from the overload on the outside wheels by the more or less significant tilting of the vehicles...

The main runway of Lorient-Lann Bihoud airport was overlayed with continuously reinforced concrete in 1989. This operation is examplary because from the technical viewpoint it is still today the only one in Europe. This runway is used now for eight years by civil and military traffic. The cracking development is...

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...
