| 摘 要： | 采用高速剪切设备,以70~#沥青,0.60 mm(30目)废轮胎橡胶粉制备废胶粉改性沥青.利用红外光谱(IR)、热重(TG)、扫描电镜(SEM)和动态剪切(DSR)分析的方法,分析了废胶粉微观结构对改性沥青性能的影响,研究了两者之间相互作用的机理.结果表明:废胶粉与沥青能够均匀混合,既有物理共混又有化学反应,形成稳定的整体,具有良好的相容性;胶粉颗粒的表面网状结构可很好地吸附沥青,使沥青黏度增大,感温性降低;动态剪切试验证明,胶粉改性沥青呈非均相,具有复杂的相态结构;沥青的技术性能得到改善,为废胶粉改性沥青的进一步应用提供了微观理论上的依据.

| Abstract: | Waste crumb rubber-modified asphalt was made of 70~# asphalt and 0.60 mm waste crumb rubber powder by a high-speed shearing machine.Model tests were carried out for base asphalt and crumb rubber modified asphalt by IR,TG,SEM and DSR to analyze the influence of waste crumb rubber's microstructure on the capability of modified asphalt.The test results show the interaction mechanism between them.The crumb rubber can be evenly mixed with the asphalt by both physical blending and chemical reaction to form an int... |
