Abstract: In order to study the effect of warm mix agents type and dosage on rheological property of different asphalts, temperature sweep experiment was tested for SBS modified asphalt and matrix asphalt mixed with RH and Evotherm warm mix agent by using Dynamic Shear Rheometerfor (DSR), and the complex shear modulus, phase angle and rutting factor of two kinds of asphalt were analyzed. The results show that Evotherm can improve the rutting resistance of two kinds of asphalt when the temperature is between 28℃ and 52℃, and the influence of Evotherm is weakened at temperature higher than 52℃. Evotherm can also improve the elastic recovery performance of two kinds of asphalt when the temperature is between 28℃ and 40℃, but it reduces the elastic recovery performance of SBS modified asphalt and has no effect on matrix asphalt at temperature higher than 40℃. The raise of Evotherm dosage can improve the rutting resistance of SBS modified asphalt and slightly reduce the rutting resistance of matrix asphalt when the temperature is between 28℃ and 52℃, and the influence is not obvious at temperature higher than 52℃. RH warm mix agent has a slightly adverse effect on anti-rutting performance when temperature is between 28℃ and 46℃, but the negative effect gradually weakens or even disappears with the rising of temperature, and RH warm mix agent can significantly increase the elastic recovery performance at high temperature of two types of asphalt. The increase of RH warm mix agent dosage will reduce anti-rutting performance but enhance the elastic recovery performance of two kinds of asphalt.
