چکیده مقاله
The monotonic steady state deformation and recovery behavior of a standard pure bitumen, using Dynamic Shear Rheometer DSR is investigated Constant stress creep and creep recovery tests at 10C and 20C over a range of stress levels have been conducted The steady state deformation behavior of the bitumen is found to be linear at low stress levels and non linear power law creep at high stress levels The records strain of the bitumen is found to increase with increasing the total strain before unloading up to a level after which the recovered strain flattens to a constant value It is also found that the recovered strain increases with increasing stress level
