摘　　要：有机降粘温拌沥青具有加工方便、施工和易性好等优点,备受人们的关注。重点比较了沥青蜡与常用有机降粘剂蜡结构性能的不同,分析了有机降粘剂改性沥青的机理,综述了有机降粘剂对沥青常规性能、流变性能和粘附性能的影响,展望了有机降粘温拌沥青的发展前景。Because of easy process and obvious energy saving property of the warm mix asphalt by adding organic viscosity - reducers, its development was attractive. The effects of natural wax on the asphalt structural performance were introduced and difference between natural wax and organic viscosity - reducers was compared. The mechanism of warm mix asphalt by adding organic viscosity -reducers was investigated. The impacts of viscosity - reducers on conventional performance, rheological properties and adhesion of asphalt were summarized. The splendid future of warm mix asphalt technology with organic viscosity - reducers was recommended in the end.
