CRCP

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....

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...

For the construction of the LIEFKENSHOEK-toll tunnel under the river Scheldt, the Flemish Road Administration has once again chosen CRCP, 20 cm thick, as the best solution for the pavement inand outside the tunnel. By also choosing CRCP for the 30.000 m 2 diamond shaped toll-square, it was possible to...

As a number of CRC sections were gradually reaching a respectable age, the CRIC undertook an investigation in 1990 on possible corrosion of reinforcements. The close average spacing ot cracks (40 to 60 cm) in sections with 0.85% of steel and a bituminous base course was surprising. On the other...

In the Netherlands Rijkswaterstaat is the authority in charge among others of the construction of highways. The department Limburg of Rijkswaterstaat has chosen a continuously reinforced concrete roadbase for the construction of the 12 km long new highway section between the cities of Venray and Boxmeer. This choice was based...
