Asphalt pavement patching material as well as preparation method and application thereof
The invention relates to an asphalt pavement patching material as well as a preparation method and application thereof. The asphalt pavement patching material is prepared from the following components in parts by weight: 430 to 470 parts of dead burned magnesium oxide, 135 to 170 parts of ammonium dihydrogen phosphate, 210 to 220 parts of fly ash, 40 to 45 parts of silica fume, 40 to 50 parts of borax, 30 to 40 parts of sodium tripolyphosphate, 1000 to 1200 parts of quartz sand, 1 to 130 parts of emulsified asphalt, 110 to 150 parts of water and 70 to 90 parts of temperature-sensitive shape memory material. The asphalt pavement repairing material has proper setting time and flowability, can quickly repair a complex pavement, has good expansibility, has deformation performance similar to that of an old asphalt pavement, and can form a stable integrated structure with the old asphalt pavement area. In addition, the asphalt pavement patching material is good in rainwater erosion resistance and long in service life.
本发明涉及一种沥青路面修补材料及其制备方法和应用。按重量份数计，该沥青路面修补材料包括：包括重烧氧化镁430～470份、磷酸二氢铵135～170份、粉煤灰210～220份、硅灰40～45份、硼砂40～50份、三聚磷酸钠30～40份、石英砂1000～1200份、乳化沥青1～130份、水110～150份、温敏形状记忆材料70～90份。该沥青路面修补材料具有合适凝结时间、流动性，可以快速修补复杂路面，且膨胀性好、与旧沥青路面具有相近的变形性能，能与旧沥青路面区形成稳定的一体结构。此外，该沥青路面修补材料抗雨水侵蚀性好，使用寿命长。
