采用动态剪切流变仪对不同老化条件沥青砂浆进行性能测试，分析其路用性能。结果表明：紫外和热氧老化会改善沥青砂浆的高温稳定性，水损害则会弱化沥青砂浆的稳定性；同时，紫外和热氧老化还会在一定程度上对砂浆的低温应力松弛性能造成损害，加快沥青路面的低温开裂，但是水损害却能够提高沥青砂浆的低温应力松弛性能。

Dynamic shear rheometer(DSR)was used to measure the pavement properties of asphalt mortar on dif-ferent aging conditions.Its results showed that:ultraviolet(UV)and thermal oxygen(TO)aging could improve the high-temperature stability of asphalt mortar,moisture damage could reduce the high-temperature stability of asphalt mortar;UV and TO aging could also damage the low-temperature stress relaxation properties,but moisture damage is opposite.
