摘　　要：通过对比基质沥青和解交联橡胶沥青的针入度、软化点、延度以及力学性能和流变特性等,证明了解交联橡胶对沥青性能的提高效果;通过傅里叶变换红外光谱(FTIR)、X射线光电子能谱(XPS)、核磁共振波谱(NMR)等手段,研究了解交联橡胶与沥青间的相互作用,证明了两者共价键、氢键、配位键等相互作用,结果将有助于促进橡胶沥青在道路领域的标准化、规模化应用。The physical properties of devulcanized rubber modified asphalt including penetration,softening point,ductility,mechanical properties and rheological properties were studied.At the same time,the interaction between devulcanized rubber and asphalt was investigated using advanced analytical techniques such as Fourier Transform Infrared Spectroscopy(FTIR),X-Ray Photoelectron Spectroscopy(XPS),and Nuclear Magnetic Resonance Spectroscopy(NMR),which proved the interaction of covalent bonds,hydrogen bonds and coordination bonds between devulcanized rubber and asphalt.The results were expected to provide guideline for the application of devulcanized rubber asphalt.
