使用老化试验方法，“通过压制薄膜样品的UV老化试验”，检查了普通沥青和改性沥青II型结合料的老化行为。结果表明，该方法能有效地模拟户外曝晒试验，与压力老化容器试验条件相比，紫外线对表面的损伤是一个严重的因素，炭黑的加入有防止老化引起的化学组分变化和抑制紫外线辐射引起的羰基生成的趋势。因此，炭黑将提高沥青材料的耐久性。
Using an aging test method, “UV Aging test by pressed thin film samples”, a straight asphalt and a modified asphalt type-II binder were examined for their aging behavior. The results confirmed that this method is effective to simulate the outdoor exposure test, and ultraviolet-rays radiation is a severe factor to the surface compared with the conditions of the Pressure Aging Vessel test.Furthermore, addition of carbon black showed the tendency to prevent from changing in the chemical fraction by aging, and to restrain the producing of carbonyl group by ultraviolet-rays radiation. Therefore, carbon black will improve the durability of asphalt materials.
