Phase-change temperature self-adjusting asphalt mixture for road and preparation method of phase-change temperature self-adjusting asphalt mixture
The invention discloses a phase-change temperature self-adjusting asphalt mixture for a road and a preparation method of the phase-change temperature self-adjusting asphalt mixture, and belongs to the technical field of asphalt mixtures. The phase-change temperature self-adjusting asphalt mixture for the road is prepared from the following raw materials in parts by weight: 4.8 to 6 parts of asphalt, 107.5 to 108.6 parts of aggregate, 0.3 to 0.6 part of a composite phase change material and 5.9 to 6.5 parts of mineral powder. The aggregate, the mineral powder and the asphalt are respectively dried, the aggregate, the asphalt, the mineral powder and the composite phase-change material are added into a stirring pot, and uniform stirring is conducted to obtain the phase-change temperature self-adjusting asphalt mixture for the road. The phase-change temperature self-adjusting asphalt mixture for the road is used for actively adjusting the temperature of the road surface, and an indoor cooling test and an outdoor cooling test show that the mixture has a good cooling effect and good road performance, is suitable for expressways and urban roads, and has a wide application prospect.
本发明公开了一种路用相变温度自调节沥青混合料及其制备方法，属于沥青混合料技术领域。本发明的路用相变温度自调节沥青混合料，包括如下重量份的原料：4.8～6份沥青、107.5～108.6份集料，0.3～0.6份复合相变材料，5.9～6.5份矿粉。将集料、矿粉和沥青分别烘干后，在搅拌锅中加入集料、沥青、矿粉和复合相变材料，搅拌均匀即可得到路用相变温度自调节沥青混合料。本发明的路用相变温度自调节沥青混合料用于实现主动调节路面的温度，经过室内降温试验和室外降温试验发现，该混合料有很好的降温效果，路用性能良好，既适用高速公路，同时也适用城市道路，具有广阔的应用前景。
