摘要
本文在0.12～0.30MPa(O_2)、25～80℃条件下,详细考察了温度和氧压对欢三联直馏沥青和欢喜蛉氧化沥青吸氧老化性能的影响,提出了包含氧压、温度、时间和吸氧量在内的完整吸氧动力学模型,并着重分析了温度和氧庄与总包速度常数或总包最大吸氧量间的关系,揭示了两种不同类型沥青吸氧老化的本质和区别。
The effect of temperature and oxygen pressure on the oxygen absorption aging properties of Huansanlian straight asphalt (HSL) and Huanxiling oxidized asphalt (HXL) have been inverstigated under 0.12～0.30MPa (O_2) and at 25～80℃. The kinetic model covered oxygen pressure, temperature, reaction time and amount of oxygen absorbed was presented. The relationships between the oxygen pressure, the temperature and the overall rate constant or the overall maximum amount of oxygen absorbed were emphatically studied. The aging rules and the difference of the two asphalts from different origins were also studied.
