Approximately 5000 years ago, a small dam was built in the Indus river valley, using asphalt as a mortar between stones. That was one of the first utilization of asphalt as an impervious material. However, the first modern asphalt concrete core dam, mechanically placed and compacted, was built in Germany in 1962.

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 pr?sente l?tat actuel des derni?res pratiques suite aux d?veloppements importants en conception et en construction accomplis au cours des 25 derni?res ann?es. Il renferme tous les aspects de la conception, de la construction, du comportement et de lexploitation. Les caract?ristiques des noyaux de b?ton bitumineux, les exigences pour la conception des m?langes, les essais en laboratoire et le contr?le de la qualit? sont analys?s. Le devis descriptif est ?galement pr?sent? et propos?. Pour terminer, plusieurs cas-types, accompagn?s des caract?rist
