To improve the surface quality or the water drainage and the service life of a mediocre damaged concrete pavement, this pavement can be overlaid with a 4 to 6 cm thick asphalt layer. The status of the concrete pavement and of the joints with respect to potential reflection cracks needs...
Evaluation of Concrete Pavements on the Restauration with Thin Aspahit Layers
First Application of a Concrete Inlay on a Bitumen Paved Motorway in Belgium
The motorway A7, also called the "Motorway of Wallonia", was opened to traffic in December 1970. In the vicinity of Mons this motorway carries a very high volume of heavy traffic, which is still increasing. The right-hand (slow) lane is subject to severe rutting, which has affected the deeper layers....

New Concrete Pavement Structures in the Revision of the French Catalogue of New Pavements and in the Technical Guide of Overlays
The documents for conception and design of new and reinforcement works on the French national road network were updated in 1988to take into account new pavement designs and techniques: dowelled slabs, continuously reinforced concrete, thick slabs on porous course, cement processed materials subbases. The article explains: - the development of...
The Design of Concrete Pavements and Overlays
This paper describes a method developed by the Belgian Road Research Centre for the design of cement concrete pavements and overlays. The object of this method is to avoid fatigue cracking of the surfacing (or overlay) and excessive permanent deformation of the subgrade soil. It results from the application of...
Hard Shoulders on Autobahns
Hard shoulders provide space for vehicles to stop in an emergency. They additionally provide space to function as traffic lane to keep traffic moving in the customary number of lanes if part of the carriageways is closed for repair measures. In the case of concrete pavements, the structural design and...
Lean Concrete Hard Shoulders Alongside Continuous Reinforced Concrete Overlays
Today, the great majority of Emergency Hard shoulders on Continuous Reinforced Concrete Pavement Motorways of the French network are build with full thickness lean concrete. The principle of this process (background, drainage, laying, seals, surface treatment, concrete formulas) are described below.
Evaluation of Existing Pavements and Conçrete Overlay Design in the Netherlands
Working Committee «Overlay in concrete» is founded to create a manual containing practical methods for designing and building concrete overlays for road and airport pavements for Dutch conditions. Results of the Working Committee activities are presented in this paper. A method to determine the bearing capacity of existing pavements is...
Resurfacing Flexible Pavements with Thin Layers of Concrete with Steel Reinforcement
This paper describes the studies, reports and experimental sections related to this new type of pavement, not conventional, composed of a thin concrete layer, but with a steel reinforcement, in sufficient quantity to resist the traffic loads. The description goes back to the first studies and tests carried out inthe...
