摘要
使用SEM、XRD、TG、DTA、IR等测试手段,研究当前主要使用的3类沥青温拌剂的温拌作用机理:沸石类沥青温拌剂在一定的温度下会持续分解出水分,降低了沥青粘度;有机降粘类温拌剂在高于110℃的环境下液化,使得沥青的轻质组分增加,从而分散、润滑沥青中的胶质与沥青质;乳化类沥青温拌剂具有表面活性组分,能够使得沥青形成油包水乳液,从而降低沥青粘度.
SEM,XRD,TG,DTA,IR measurements were taken to investigate the viscosity reduction mechanism of three different asphalt warm-mixed additives： Zeolites could release water at high temperature sustainably and reduce the viscosity of asphalt. Organics could transition to liquid when the temperature is higher than 110 ℃ and lubricate and disperse colloid and asphaltenes with light component increase. The surfactivity part in emulsifications could produce water-in-oil emulsions and decrease asphalt viscosity.
