Asphalt Concrete Cores for Embankment Dams / Noyaux de Béton Bitumineux Pour Les Barrages En Remblai

This Bulletin covers the state-of-the-art of current practice after the important development in design and construction during the last 25 years. It addresses all aspects of the design, construction, performance and operation. Characteristics of asphalt concrete cores, requirements for the mix design, laboratory testing and quality control are discussed. Technical specifications are also presented and proposed. Finally, several typical case histories with characteristics and performance are given in Appendices.

Ce Bulletin présente l’état actuel des dernières pratiques suite aux développements importants en conception et en construction accomplis au cours des 25 dernières années. Il renferme tous les aspects de la conception, de la construction, du comportement et de l’exploitation. Les caractéristiques des noyaux de béton bitumineux, les exigences pour la conception des mélanges, les essais en laboratoire et le contrôle de la qualité sont analysés. Le devis descriptif est également présenté et proposé. Pour terminer, plusieurs cas-types, accompagnés des caractéristiques et du comportement, sont relatés en annexe.

The Commission Internationale des Grands Barrages (CIGB) / International Commission on Large Dams (ICOLD) is a non-governmental International Organization which provides a forum for the exchange of knowledge and experience in dam engineering.

The Organization leads the profession in ensuring that dams are built safely, efficiently, economically, and without detrimental effects on the environment. Its original aim was to encourage advances in the planning, design, construction, operation, and maintenance of large dams and their associated civil works, by collecting and disseminating relevant information and by studying related technical questions.
Since the late sixties, focus was put on subjects of current concern such as dam safety, monitoring of performance, reanalysis of older dams and spillways, effects of ageing and environmental impact. More recently, new subjects include cost studies at the planning and construction stages, harnessing international rivers, information for the public at large, and financing.
