| 摘 要： | 以石灰石矿粉、水泥和消石灰为填料，按不同的粉胶比制备成沥青胶浆，采用低温弯曲试验，研究了不同填料和不同粉胶比对胶浆低温性能的影响。结果表明胶浆在低温抗裂性方面存在最佳粉胶比。不同填料的胶浆最佳粉胶比是不同的，而且，掺加水泥和消石灰有助于提高胶浆的低温抗裂性能。

| Abstract: | The different filler sorts such as limestone dust, cement and hydrated lime, and different ratios of filler/asphalt which influence properties of asphalt mortars' are studied by a bending test at low temperature. The results show that there is an optimal ratio of filler/asphalt at the aspect of low temperature cracking resistance for asphalt mortars, different asphalt mortars have different optimal ratios, and cement and hydrated lime are helpful to low temperature cracking resistance of asphalt mortars. |

| Keywords: | asphalt mortar ratio of filler/asphalt cement hydrated lime low temperature cracking resistance |
