The asphalt core is located between the upstream and downstream transition zones that are simultaneously placed and compacted in the central part of the embankment dam to form a strong interlocking asphalt core–gravel transition zone (AC-GTZ) interface. The asphalt core usually settles a little more than the transition zones during dam construction, and AC-GTZ interface shear displacements develop. Shear tests were conducted in the laboratory to investigate the interface behavior. Test results show that the AC-GTZ interface was gradually deformed up to a shear displacement of 60 mm, but the properties of the asphalt surface layer did not deteriorate. The integrity of the asphalt core would be better maintained if a sliding layer is placed between the core and the transition zone.
