Cush Kobita Bea Hydropower Station is located in cold region of Xinjiang ,which leaves shorter time for the construction of asphalt concrete core wall of the rolled earth-rock dam .In order to shorten the construction time and make it possible for the station to operate in advance ,the mix propotion of asphalt concrete core wall were studied for winter low temperature construction .The construction process were simulated at -25℃ to test for resolution ,performance be-tween the layers ,compaction effect ,permeability of contact face and physical-mechanical properties of the asphalt con-crete .The results indicate that the properties of the asphalt concrete can meet the design requirements .
