目前市场上，高粘度添加剂这种材料，不管是进口的还是国产的，归根到底是一种以橡胶—SBS聚合物改性剂、树脂、硅藻泥及抗氧剂为主要原材料的高性能聚合物改性材料，这种材料可以有效的对道路沥青进行改性，而且效果比单纯的SBS要好得多，主要体现在能大幅提高沥青的软化点以及粘度。一般来说，高粘度添加剂可以使用在任一沥青路面，尤其适合开级配沥青混凝土结构和应力吸收层。
At present, the material of high viscosity additive, whether imported or domestic, is in the final analysis a kind of high performance polymer modified material with rubber-SBS polymer modifier, resin, diatom mud and antioxidant as the main raw materials. This material can effectively modify road asphalt, and the effect is good. It is much better than SBS, which can greatly improve the softening point and viscosity of asphalt. Generally speaking, high viscosity additives can be used in any asphalt pavement, especially for open graded asphalt concrete structure and stress absorbing layer.
