Superplasticised Concrete For Urban Paving

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 the day of manufacture or a day later. Therefore, the use of these concretes is particularly appropriate in cases where it is possible to close the road to traffic only for short periods and where the pavement has to be opened to traffic very soon after laying. This contribution deals with the structural design and construction of traffic areas with superplasticised concrete in urban paving with reference to recently completed projects and offers advice for a durable pavement.
