CRCP

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...

Since 1982 experimental sections of thin overlays have been constructed for an amount of 171.000 m'. Eight of these sections are made of 10 to 12 cm thick steel fibre reinforced concrete, six of them on a bituminous underlayer and two on old concrete pavement. Four other sections should verify...

During the last years, many CRCP overlays have been made in Belgium. One of them has been laid in 1988 on highway E 40 in the province of Liège (8,250 km). The paper gives the reasons of the choice of CRCP for the renewal of the highway and describes the...

Reinforcement stress and crack width has been in-vestigated in full scale experimental pavement ofContinuously Reinforced Concrete Pavement forthree years. The validity of designequation for pre-dicting crack width distributed through the thick-ness of the slab and reinforcement stress etc.,which is based on bond stress -slip relationshipconsidering the effect of both concrete...

The dream of concrete pavement constructors, to replace the conventional difficult-to-fix reinforce-ments, which require a considerable manual work-force, with a continuous bobbin-wound reinforce-ment, has today become a reality. The chosensolution was a weldable carbon steel, with an elas-ticlimitgreater than 700MPA, a rectangular cross-section 40 mm x 2 mm, slotted for...

The paper reviews the reasons for continuously reinforced pavement design, and the economics of the choice of paving method. The current UK specification, its limitations and the potential va-riance with European and American specificationsare considered with its effect on the historic UKmarket, together with an opinion of the futuremarket.For the...

This paper proposes a theoretically sound method of modeling the reliability function of pavement sections, using a statistical procedure that can correctly consider test sections that have not yet reached failure. Consistent and accurate reliability estimates were obtained applying this method to a continuously reinforced concrete pavements (CRCP) data base...

Generally due to an unsufficient vibration, the concrete around the construction joints may contain cavities, especially under the reinforcement. When very hot weather conditions prevail, these deficiencies may cause important deteriorations, possibly with mere fragmentation of the concrete around the joint. As there are over 5.000 construction joints on the...

Since 1983, most of the work sites in France using Continuously Reinforced Concrete have been for overlaying work on existing motorways in service. As regards methods and equipment, this has necessitated high output production facilities to allow work to be complete as quickly as possible so as to minimize inconvenience...
