The aim of study is to evaluate rutting with Marshall Quotient (MQ) and repeated creep (RCT). Three hydrated lime (HL) mixtures were evaluated and compared with control mixtures (CMs) for conditioned samples (CSs). Filler was reduced and HL was substituted at 2%, 4% and 6%. Damage system (ECS) based on moisture was applied. For rutting with MQ approach also some mixtures were produced including SBS and HL. Modified and synergistic (SBS and HL) mixtures were interrogated. An observed damage level was exposed with the selected ECS. RCT was quite effective at different HL ratios for HL efficiency for dense gradation. HL was found beneficial due to moisture. Increasing of HL from 2% to 6% deformation resistance increased. Tertiary deformation was not revealed at 64,730 pulses for CM and HL ones. Expected results were obtained with the RCT for both HL mixtures and also SBS. MQ is not a good indicator of the deformation resistance because of the larger intervals between CM and others.
► Rutting potential of control, hydrated lime (HL) and HL–SBS modified mixtures were evaluated. ► Conditioned and unconditioned samples were tested with repeated creep and Marshall Quotient. ► Hydrated lime modification was found beneficial in view of water sensitivity. ► With the increasing of hydrated lime from 2% to 6% rutting resistance increased. ► It was found that MQ may not be a good indicator for measuring of the rutting resistance.
