摘要
研究了橡胶沥青在紫外光老化过程中结构与性能变化规律。以软化点为指标分析橡胶沥青在紫外老化条件下性能的变化,发现其软化点增长速度慢于基质沥青,羰基、亚砜基吸收峰的变化小于基质沥青。结果表明,橡胶沥青相对基质沥青具有较强的耐紫外老化性能。
In this paper, property and chemical structure changes were investigated to characterize the influence of ultraviolet radiation in the sun on asphalt rubber pavement. The softening temperature was tested for performance variation of asphalt rubber. Furthermore, The absorption peaks of carbonyl group and sulfoxide group were also used to analyze ultraviolet resistance properties of asphalt rubber using Attenuated Total Reflection Fourier Trans-form Infrared Spectroscopy （ATR-FTIR）. The results indicated that asphalt rubber has better ultraviolet resistance than base asphalt.
