Abstract： As foaming agent for the preparation of zeolite-foamed asphalt, the foaming water released from EC130 warm-mix additive and the residual zeolite minerals have different effects on the properties of asphalt. To investigate the effect of EC130 warm-mix additive on the high temperature performance and fatigue resistance of SBS modified asphalt, three additives of limestone powder, EC130 zeolite mineral and EC130 warm-mix additive were used, and the single-factor test was designed with additive dosage as variable. By temperature scan test, multiple stress creep recovery test and linear amplitude sweep test, the effects of EC130 zeolite mineral and foaming water released from EC130 warm-mix additive on the high temperature performance and fatigue resistance of SBS modified asphalt were compared and analyzed with reference to the effect of limestone powder on asphalt properties. The results show that like limestone mineral powder, the EC130 zeolite mineral in zeolite foamed asphalt can increase the elasticity and decrease the viscosity, which is favorable for rutting resistance but unfavorable for fatigue resistance. The foaming water in zeolite foamed asphalt can increase the viscosity and decrease the elasticity, which is favorable for fatigue resistance but unfavorable for rutting resistance.
