摘　　要：模拟沥青不同老化时间制备试样,研究其红外谱图的变化规律,通过选取羰基、亚枫基峰面积与沥青特征峰面积的比值变化来评价沥青的老化性能;结合不同老化时间沥青性能指标的数据,关联沥青老化时间和沥青性能衰减的关系,为沥青质量现场控制提出建议。The samples were prepared for different aging times of asphalt,and the change rule of infrared spectrogram was studied.The aging performance of asphalt was evaluated by selecting the ratio change of carbonyl and alphumyl peak area and characteristic peak area of asphalt.Based on the data of asphalt performance indexes of different aging times and the relation between asphalt aging time and asphalt property attenuation,the paper puts forward some advice for the field control of asphalt quality.
