Asphalt core dams play an important role in managing and protecting water resources around the world. Such dams have excellent performance, particularly in terms of seepage control and stability. For example, a study at the Megech Dam in Ethiopia showed that asphalt concrete core dams are more effective in seepage control than clay core dams. In addition, the construction of asphalt core dams is less affected by weather conditions, reducing construction time and therefore costs. Countries such as Europe, Japan, China and Norway have built many such dams over the last 50 years, and now Brazil and Canada are building their first dams. Asphalt-core dams are important not only as an engineering achievement, but also for environmental sustainability; asphalt is a natural, non-toxic material that is ideal for drinking water reservoirs and does not harm the environment. These dams are particularly suitable for dams located in earthquake zones or on compressible soils, as the properties of asphalt concrete can be tailored to specific design criteria. Asphalt core dams offer an innovative and effective solution for managing and protecting water resources around the world.
