Cold-mixed and cold-laid emulsified asphalt mixture and preparation method thereof

The invention relates to the technical field of road building materials, in particular to a cold-mixed and cold-laid emulsified asphalt mixture and a preparation method thereof. Compared with the prior art, the emulsified asphalt can be stored stably for a long time, the mixture can be demulsified as soon as possible after being paved on a pavement, traffic can be opened as soon as possible, and the aggregate is wide in application range and suitable for any cold construction process of the pavement, such as micro-surfacing, sand-containing fog sealing layers and the like. The cement pavement changes white into black, is energy-saving and environment-friendly, breaks through the limitation of thermal insulation conditions in the transportation process of the traditional hot mix mixture and the strict limitation of temperature conditions in the compaction process, and is convenient to construct. 本发明涉及道路建筑材料技术领域，特别涉及一种冷拌冷铺的乳化沥青混合料及制备方法。与现有技术相比，本发明既保持乳化沥青长期储存稳定，又使混合料摊铺在路面后能够实现尽快破乳、达到尽早开放交通，集料适用范围广，适用于路面任何冷施工工艺，如
