| 摘 要： | 通过添加不同剂量的Domix沥青混合料与4.5%SBS改性沥青混合料性能对比后发现,Domix沥青混合料动稳定度高,且随试验温度的提高,沥青混合料的抗车辙性能衰减很小;运用低温弯曲破坏应变不能很好地表征Domix沥青混合料的低温抗裂性能,提出弯曲应变能密度可以很好地评价Domix沥青混合料的低温抗裂性能;Domix沥青混合料水稳定性能满足规范要求。

| Abstract: | By adding dltlerent （loses oI DOmlX aspnau mixture anu ,-r.J-/u o~,o .,~,u＊~ t＂ - paper compared two kinds of asphalt mixture performances. And it found that the Domix asphalt mixture dynamic stability was high. With the increase of test temperature, the anti-rutting performance of the asphalt mixture reduced. It also put forward that the bending strain energy density could evaluate the low temperature crack resistance of Domix asphalt mixture well. |
