Continuously Reinforced Concrete on Bridges

Conf-paper-iscr

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...

Monitoring Program for a Continuously Reinforced Concrete Roadbase in the E35 Highway in the Netherlands

Conf-paper-iscr

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 with Continuously Reinforced Concrete Pavements

Conf-paper-iscr

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...

Overlaying and Behavior of Lorient-Lann Bihone Main Runway with Continuously Reinforced Concrete (CRC)

Conf-paper-iscr

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...

A Design Method of Composite Pavement with Asphalt Surface Course and Continuously Reinforced Concrete Base Course

Conf-paper-iscr

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 Pavements – from a Classical Conception to An Innovative Structure

Conf-paper-iscr

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...

A CRCP Inlay for the Rehabilitation of a Deteriorated Concrete Pavement on a Motorway with Very Heavy Traffic

Conf-paper-iscr

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

Positive Results Obtained from CRCP Projects in France (1988-1991)

Conf-paper-iscr

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

Continuously Reinforced Semi-Rigid Pavements – Experiment and Development

Conf-paper-iscr

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...

Continuously Reinforced Concrete for the Diamond-Shaped Toll Square and the Pavement of the Licfkcnshocktunnol in Antwerp (Belgium)

Conf-paper-iscr

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...

Cracking and Corrosion in Continuously Reinforced Concrete Pavements

Conf-paper-iscr

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...

Continuously Reinforced Concrete Road Bases

Conf-paper-iscr

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...
