为了适应现代交通(轴载重、数量大、渠化行驶)的发展需要,近十年来世界许多国家都在致力于沥青性能的改善和提高。运用高分子聚合物进行沥青结合料的改性,已经越来越为许多研究人员和厂商所关注。有些聚合物改质沥青已用于快速干道和桥面。在我国已有的橡胶粉改性沥青材料,虽然可以改善国产沥青的某些弹粘性、温度敏感性及粘附能力。但是这类改性沥青尚不能获得十分满意的路用品质,例如它的马歇尔稳定
In order to meet the development needs of modern transportation (axle load, large quantity and canalization), in recent ten years, many countries in the world are devoted to the improvement and improvement of asphalt performance. The use of polymers for asphalt binder modification, more and more researchers and manufacturers have been concerned about. Some polymer-modified asphalt has been used for fast roads and decks. In our country, the existing rubber powder modified asphalt material, although it can improve some of the domestics of China-made bouncing, temperature sensitivity and adhesion. However, this type of modified asphalt can not yet get very satisfactory road quality, such as its Marshall stability
