Abstract

The Roller Compacted Concrete (RCC), which is presented as an evolutionary technology for a large diversity of applications (Dams, roads...), is considered, like conventional concretes and other construction materials, as an elastic material. The RCC in pavement supports many stresses which involve deformations and reciprocally. The knowledge of the relation between strength and deformation, for a material such as the RCC, presents a capital interest for the structural design of rigid pavements. The authors treat, in this work the experimental evaluation and the estimation, through a model, of the Young's elastic modulus E of the RCC for pavement manufactured with low cement proportioning. This work includes experimental measurements of the elastic modulus E on standardized specimens prepared according to the method of the French National Project "BaCaRa". It contains also the comparison of the measured modulus with those estimated by the models.
