Water damage-resistant foamed asphalt mixture and preparation method thereof
The invention discloses a water damage-resistant foamed asphalt mixture and a preparation method thereof, belongs to the technical field of asphalt mixtures, and aims to solve the problem of water damage caused by asphalt foaming water and mixture mixing water in the conventional foamed asphalt cold-recycling mixture. The water damage-resistant foamed asphalt mixture is formed by mixing aggregate,water and foamed asphalt, wherein the aggregate comprises the following components in parts by mass: 75-90 parts of an asphalt mixture reclaimed material, 4-20 parts of stone chips, 3-5 parts of mineral powder, 1-2 parts of cement, 0.3-1.5 parts of zinc oxide powder and 1-5 parts of a coupling agent solution, wherein the foamed asphalt contains an amine anti-stripping agent. According to the water damage-resistant foamed asphalt mixture, the surface of the recycled asphalt mixture is modified by doping the zinc oxide powder and the coupling agent, and the asphalt is modified by doping the anti-stripping agent so that the water damage resistance and the low-temperature performance of the foamed asphalt cold-recycled mixture are improved.
抗水损害型泡沫沥青混合料及其制备方法，本发明属于沥青混合料技术领域，它要解决现有泡沫沥青冷再生混合料因沥青发泡用水及混合料拌和用水所产生的水损坏问题。本发明抗水损害型泡沫沥青混合料由集料、水和泡沫沥青拌和而成，其中集料按照质量份数包括75～90份的沥青混合料回收料、4～20份石屑、3～5份矿粉、1～2份水泥、0.3～1.5份氧化锌粉末和1～5份偶联剂溶液；其中泡沫沥青中含有胺类抗剥落剂。本发明所述抗水损害型泡沫沥青混合料通过掺加氧化锌粉末和偶联剂对沥青混合料回收料表面进行改性，通过掺加抗剥落剂对沥青进行改性，进而提高泡沫沥青冷再生混合料的抗水损害性能和低温性能。
