Through road performance comparison and verification of various schemes, it is found that modified asphalt behaves a stronger anti-ultraviolet aging ability than base asphalt;
通过不同方案的路用性能比较和验证，发现基质沥青添加改性剂比单独使用基质沥青具有更强的抗紫外老化能力；
The results showed for ultraviolet ray protection daiflon coating was the best, anti - aging film was better and the resin rich protective coating was the worst.
结果表明，聚三氟乙烯涂层对紫外线的防护效果最好，防老化薄膜次之，富树脂保护层最差。
So it fits to be used in south and altiplano with high intensity of ultraviolet radiation, especially for open-graded pavement with high request of anti-aging.
适合于南方和高原紫外线强烈地区使用，尤其适用于对老化性能要求较高的开级配道路。
