| 摘 要： | 紫外线辐射是导致沥青老化的主要因素之一.研究了沥青紫外老化前后的物理性能与流变性能,并与热老化前后的物理性能与流变性能进行了对比.低温弯曲梁流变试验(BBR)表明沥青紫外老化后低温抗裂性能减弱.因此,在强烈紫外线作用下导致沥青使用寿命明显缩短,并会产生一系列相关路面病害.

| Abstract: | Ultraviolet radiation is one of the main factors induce asphalt binder aged in the field in-service. Physical and rheological properties before and after ultraviolet aging are investigated, the influence for asphalt performance of ultraviolet radiation aging with thermal aging are compared. Low-temperature bending beam test result also reveal that bitumen's thermal cracking resistances became poor due to ultraviolet aging. Since the remarkable shorten of life span of the asphalt pavement and some problems associated with binder-related pavement failures in the intensive ultraviolet radiation climates. |
