High-performance cement-emulsified asphalt mixture and preparation method thereof
The invention belongs to the technical field of road engineering, and discloses a high-performance cement-emulsified asphalt mixture and a preparation method thereof. The high-performance cement-emulsified asphalt mixture comprises coarse aggregate, fine aggregate, emulsified asphalt, a mineral filler, an additive and water. The preparation method comprises the following steps: fully mixing waterfor mixing, the emulsified asphalt, the mineral aggregates, the filler and the additive in a mixing device, uniformly stirring, carrying out magnetization treatment on the obtained mixture through a magnetic field with a preset intensity according to a certain discharge rate, and carrying out paving molding through a paving machine. The asphalt mixture prepared by adopting the preparation method and the optimized material blending proportion shows excellent construction workability and pavement effect; and compared with a traditional cold-mixed asphalt mixture, the mixture of the invention hasthe following advantages: the strength forming time is short, the splitting strength of the mixture is obviously improved, and the fatigue life of the mixture is obviously prolonged.
本发明属于道路工程技术领域，公开了一种高性能水泥乳化沥青混合料及其制备方法。一种高性能水泥乳化沥青混合料成分如下：粗集料、细集料、乳化沥青、矿物填料、添加剂、水。其制备方法：先将拌合用水和乳化沥青与矿料、填料、添加剂在拌合设备中进行充分混合，搅拌均匀，再将混合料按照一定出料速率通过设定强度的磁场进行磁化处理，紧接着由摊铺机械摊铺成型。采用该制备方法及优化的材料掺配比例配制得到的沥青混合料呈现出优异的施工和易性及路用效果；与传统冷拌沥青混合料相比强度形成时间更短，混合料的劈裂强度及疲劳寿命提升明显。
