摘要:
为了研究沥青热氧老化的时间规律,利用室内旋转薄膜(RTFOT)试验,根据系统工程科学理论和非线性科学的灰色突变理论模型,对不同老化程度的沥青性能指标值进行灰色生成处理,建立沥青老化的灰色尖点突变模型,对沥青热氧老化的规律进行分析.结果表明,沥青的老化过程存在突变现象,且其性能突变与老化反应之间存在滞后现象,沥青混合料拌合和热储存时间应保证小于50 min,沥青路面应采取适当措施延长老化突变时间,使路面具有更长的服务寿命.
Abstract:
In order to forecast the time regularity of the asphalt thermal and oxygen aging,the RTFOT experi-ment was applied,according to the principle of evaluating system stability with the variable tendency of itscompatibility,the destabilization of asphalt aging was predicted with the grey-cusp-catastrophic destabilizationprediction model. The research results show that the catastrophe exits in the aging process, and hysteresis phe-nomenon exits between catastrophe and aging actions. For the asphalt mixture,the heating time should not ex-ceed 50 min, and to make the asphalt pavement have the long services life,the measures should be taken toextend the catastrophic happened time.
