摘要
太阳光中的紫外线对沥青能产生光老化作用,为改进沥青的抗紫外老化性能,采用添加抗紫外剂的方法,通过考察软化点、黏度和流变性能对其抗紫外老化性能的影响,研究沥青抗紫外老化的工艺。结果表明:紫外光吸收剂可以改善沥青的抗紫外老化性能,并提高沥青的抗裂能力。
Ultraviolet ray in sunshine can accelerate the aging process of asphalt.The anti-ultraviolet aging technique was studied by comparing several different modified asphalt samples in respect of softening point,viscosity and rheological property.Results showed that adding UV absorber can improve the anti-ultraviolet aging performance of asphalt as well as the anti-cracking ability of asphalt.
