Tostudytheinfluenceofdifferentwarm-mixedagentsonasphaltperformanceinhot and damp region， As pha-min， EC-120， EC-130， Saso bit， HPS-1warm-mixed agents were selected to 70^#asphalt.Three major indexes test， dynamic viscosity test， brookfield vis-co sity test， dynamics hear rheometer test， adhesion test and toughness test were carried out to study the influence of different warm-mixed agents on the properties of asphalt.The results show that EC-120andsasobit can improve the ability of resisting high temperature rutting； EC-120andsasobit are better than other three warm-mixed agents in improving the ability of adhesion level and toughness.The performance indexes of EC-120andSasobit are preponderant， so it can be considered as the priority in the hot and damp area.
