Ceres Dam, situated in the mountains above Ceres in the Ceres Valley, South Africa is a 60m high Rock-Fill asphalt Core Dam with a 387m crest length. This is the first dam on the African continent built using this technique -asphalt. During the massive earthquake in 1969 the old concrete dam was severely damaged and had to be replaced. Replacing/rebuilding a new structure made it possible to increase the reservoir from the existing 0.4 million m³ to 17million m³.
The asphalt core is 50cm wide and has filter zones on both the up-stream and the Down Stream side. Each filter core measures 1.5m. 4500m³ of prepared asphalt was used to complete the dam.
