Several years ago, a new generation of concrete, the ultra high performance fibre-reinforced concretes have been introduced. We have developed a range of products based on such new technology. The ultra high performance concrete developed is the result of an optimisation of the nature and the composition of different raw materials. It is composed of a premix, a new superplasticizer, fibres and water. Otherwise, numerous investigations have been carried out on this ultra high performance concrete such as plasticity, workability time, compressive strength, flexural strength, shrinkage, coating system, bonding, …. The ultra high performance concrete described in this paper was used for the carrying out of the tollgate roof of the viaduct at Millau, Southern France. This structure is part of the A75 motorway from Clermont-Ferrand to Montpellier.
