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...

A number of research projects relating to the cementbound sub-base (CBSB) are currently in progress in the Federal Republic of Germany. Their object is to develop an optimized technological approach with a view to further improvement and even greater economy in the use of this well proven form of construction....

The resu l.cs of a research project are reported in ,which a method for the visual surveying of the condition of concreee roads was developed. In collaboration with three Federal German States, the road maintenance procedure hitherto applied was examined. The furcher investigation comprised the development of data recording sheets...
