On asphaltic roads the so called «wash-boardeffect » in front of traffic lights is a well known phenomenon. Regular reconstruction of these areas places a significant and recurrent burden on road managing authorities. Because of the large volumen of traffic at these intersections repair works also lead to a huge...

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 first known applications of RCC pavements in low-volume roads in Spain took place around 1969-1970. They included pavements located on housing developments, urban streets and rural roads. These applications have been increasing until now, when the technique is used in different parts of Spain and in other countries (Norway,...

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...

Questions regarding the environment are being particularly felt in certain countries, and noise con-trol requirements have led to the development ofthin free draining materials able to limit tirepavement contact noise.We shallbe dealingherenotwith a thin free draining pavement structure, butwith a porous concrete pavement of 40 cm thick-ness. Theoretical studies have...

Over the past few years, interest in the uses and applications of porous cement concrete for pave-ments has been growing. Its position in pavementconstruction has developed to such an extent thatit iscurrently used in places of greater importance(from shoulders to sub-bases, and even surfaces).This paper is part of the experience...

In areas with a low bearing capacity of the soil it is very hard nd expensive to manage and maintain the road system. In eneral the common pavement structures are not able to resist uring its lifetime the deformation of the subsoil caused by the eavy weight of pavement structures....

Concrete made with a superplasticiser has been used in Germany in the field of paving since the middle of the seventies. If these concretes of high workability show a high strength at a young age, they are called high early strength. These concretes can be subjected to high loading on...

In the eighties, a campaign was set up in Belgium in view of the rearrangement of the state road sections which are passing through built-up areas. These projects were meant to improve the road safety and the viability along these cross town links. Efforts were made to come to a...

This paper deals with the problem of thickness design of low-volume roads. It examines the possible use of tables of minimal thickness or analytical methods, especially developed for low-volume roads (as in France and Belgium). Attention has been paid to realise the influence of design factors, such as traffic and...

Decentralization has brought about significantly renewed interest in France in investments for regional and local roads, their rehabilitation and maintenance. Many methodological tools have been developed in the past 10 years to prepare and accompany these trends in areas in which cement concrete had played a sinall relative part in...
