Asphalt Core Dams

For more than 50 years, asphalt concrete has been used as an impermeable central (core) wall in embankment dams with a perfect no-leakage record. The very first asphaltic core dam was built in Germany in 1962. As of today, worldwide, more than 130 asphalt core embankment dams have been built. Interest in asphalt core technology has been bolstered by comprehensive research in the technology and the development of modern machinery. During the last 5 years, nine such dams have been built in North and South America.
