Overlays

Between 1982 aiid 1989, 8 thin overlay test sections were constructed with a total surface area of 129.000 m2 . The relevant research project is carried out with a view to the necessary future renovation of part of the Belgium road network. All sections were built with 10 to 12...

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...

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 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...

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.

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...

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...

The technique of con5tructin~ thick concrete overlays is at present being greatly developed in Belgium. Three periods are to be distinguished in overlay construction in this country: 1960 to 1969: experimental phase in which 210.000 m2 of overlay was constructed; 1970 to 1977: the second phase, in which the results...
