摘要
目前沥青混凝土路面早期病害问题备受关注,为延缓病害发生,沥青混合料添加剂多种多样,选择适宜的添加剂尤为重要。本文选用三种具有代表性的沥青混合料颗粒改性剂展开研究,以SBS改性沥青混合料为参照基准,对各种添加剂的应用效果做出评价,结果表明工程实践中颗粒改性剂的应用必须依据具体工程条件合理选用。
More and more researchers have focused on the early disease of asphalt mixture at present. There are varies of granular modifier for postponing the early disease. It is very important to select the appropriate additive in road construction. In this paper, three kinds of representative asphalt mixture granular have been researched. Application effect of these three kinds of additive has been assessed, based on contrasting with the SBS Modified Asphalt Mixture performance. The consequence indicated that, the granular modifier should be select- ed reasonably in the construction of asphalt pavement depended on the condition.
