Nine differently originated softening agents were tested with 100% RAP mixtures to evaluate their effect on penetration at two temperatures and low temperature embrittlement. Penetration Index (PI) was evaluated as an indicator for rejuvenation effectiveness and to predict the cracking potential. Low temperature mixture performance was tested at -10°C through determination of indirect tensile strength and creep compliance. The mixture test results confirmed the PI results and showed that the use of four from the tested rejuvenators reduced the binder consistency to the necessary level and reduced the susceptibility of the recycled mixture to low temperature embrittlement.
