技术领域：Technical field:
本发明涉及一种抗紫外线老化性能的沥青混合料。The invention relates to an asphalt mixture with anti-ultraviolet aging performance.
背景技术：Background technique:
沥青材料在道路使用过程中，在荷载以及自然环境的作用下会发生氧化、聚合等一系列的反应，导致沥青老化，路面性能退化。在中国一些太阳关辐射强烈的省份，紫外老化严重影响了沥青的使用寿命。During the road use, asphalt materials will undergo a series of reactions such as oxidation and polymerization under the action of load and natural environment, resulting in asphalt aging and pavement performance degradation. In some provinces in China with strong solar radiation, ultraviolet aging has seriously affected the service life of asphalt.
目前，低温裂缝是沥青路面的主要病害之一，严重影响车辆的行驶质量，在冰冻地区当温度降至冰点时，滞留在路面缝隙内的水分会产生冻胀，加速路面的破坏。At present, low-temperature cracks are one of the main diseases of asphalt pavement, which seriously affects the driving quality of vehicles. When the temperature drops to freezing point in frozen areas, the moisture trapped in the pavement cracks will cause frost heave, which will accelerate the destruction of the pavement.
