This paper, presents creep behavior of the concrete bituminous and it evolution under three different temperatures (17°C, 32°C, and 40°C) and their effect on the stress curves evolution at the upstream mask in the bouhnifia dam (Algeria), who is considered a rock fill dam of 55m high sealed by an upstream sealing mask in bituminous coating 20 cm thick. Creep is a time-dependent deformation resulting from constant load who is characterized by a nonlinear behavior of the materials, in which the material continues to become deform under a constant load. In this study, we have applied the Finite Element Method based on a model called (Time Hardening Model) using the computer code ANSYS 17.0 in order to simulate a creep behavior of the upstream mask during 20000 hours of loading and the evolution stress curves under three different temperatures (17°C, 32°C, and 40°C) successively. First, we simulate the temperature distribution in transient conditions during a day of sunshine on the facing, and then we evaluate the creep behavior of the mask under different temperatures mentioned above.
