ANALYSIS OF AGEING MECHANISM OF EPOXY RESIN-MODIFIED ASPHALT BASED ON INFRARED SPECTROMETRY
-
摘要: 红外光谱图与物质的结构有着十分严格的对应关系,可用于研究沥青在使用过程中的化学组成变化。通过对基质沥青、老化沥青和环氧树脂改性老化沥青的红外光谱对比分析,解析了沥青的老化机理和环氧树脂对沥青老化的抑制作用。Abstract: There is a very strict corresponding relation between infrared spectra and the structure of a matter,which may be used to study the change in chemical composition of asphalt during its use.It was analyzed that the ageing mechanism of asphalt and the inhibitation of epoxy resin on asphalt ageing through comparison of the spectra from host asphalt,aged asphalt and aged epoxy resin-modified asphalt.
