Polyurethane modified asphalt for drainage asphalt pavement as well as preparation method and application of polyurethane modified asphalt
The invention discloses polyurethane modified asphalt for a drainage asphalt pavement as well as a preparation method and application thereof, and belongs to the technical field of asphalt modification, the polyurethane modified asphalt for the drainage asphalt pavement comprises the following raw materials: matrix asphalt, a thermosetting polyurethane prepolymer, a catalyst and a compatilizer; based on 100 wt% of the addition amount of the matrix asphalt, the addition amount of the thermosetting polyurethane prepolymer is 33.3-66.7 wt%, the addition amount of the catalyst is 0.5-1 wt%, and the addition amount of the compatilizer is 0.5-1 wt%; the problems that in an existing drainage asphalt pavement technology, due to insufficient adhesion, aggregate falls off, water damage is caused by rainwater in the interior, the service life cannot be met due to insufficient structural strength, and due to the fact that in an existing polyurethane modified asphalt technology, polyurethane curing is fast, construction operability is insufficient are solved.
本发明公开了一种用于排水沥青路面的聚氨酯改性沥青及其制备方法和应用，属于沥青改性技术领域，所述用于排水沥青路面的聚氨酯改性沥青的原料包括基质沥青、热固性聚氨酯预聚体、催化剂以及相容剂；按照基质沥青的加入量为100wt％计，热固性聚氨酯预聚体的加入量为33.3‑66.7wt％，催化剂的加入量为0.5‑1wt％，相容剂的加入量为0.5‑1wt％；本发明解决了现有排水沥青路面技术存在的粘附性不足导致的集料脱落、雨水在内部造成水损害、结构强度不够满足不了服役年限，现有聚氨酯改性沥青技术聚氨酯固化快导致施工可操作性不足等问题。
