Study on Interaction Between Devulcanized Rubber and Asphalt
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 analyt-ical techniques such as Fourier Transform Infrared Spectroscopy(FTIR),X-Ray Photoelectron Spec-troscopy(XPS),and Nuclear Magnetic Resonance Spectroscopy(NMR),which proved the interac-tion of covalent bonds,hydrogen bonds and coordination bonds between devulcanized rubber and as-phalt.The results were expected to provide guideline for the application of devulcanized rubber as-phalt.
