摘要
研究了几种改性剂对沥青进行改性前后的ＤＳＣ图谱，指出改性沥青温度敏感性降低主要原因是改性剂改变了沥青组分的相转变温度，降低了相变热。并对几种改性剂改性效果进行了评价。
This paper discusses the DSC atlas of the asphalt before and after being modified by several modifiers.The author points out that the decrease of the temperature susceptiblity of the modifed asphalt is caused mainly by the changing of the temperature of the phase transition and the reducing of the heat of phase transition.The author also sets a value on the effects of several modifiers.
