摘要
本文通过日光曝晒、紫外线照射和薄膜烘箱实验比较了催化氧化沥青和普通氧化沥青耐老化性能的差异,阐述了沥青氧化催化剂的腐蚀性,报舌了催化氧化沥青的粘度,并对沥青的延伸度,针入度与油毡柔度,开卷温度的关系进行了讨论.
Based on the test results of sun exposure, ultraviolet exposure and film dryer test, the article compares catalytically oxidized asphalt with oxidized asphalt for ageing resistance In addition, it discusses the viscosity of catalytically oxidized asphalt, the corrosion of catalyst and the relationship of the ductility and penetration of asphalt to the flexibility and the unwinding temperature.
