Slow cooling type asphalt mixture for winter construction and preparation method thereof
The invention relates to the technical field of asphalt pavements, and provides a slow cooling type asphalt mixture for winter construction and a preparation method thereof. The mixture comprises the following raw materials in parts by weight: 4-6 parts of asphalt, 0.04-0.06 part of an emulsified warm mixing agent, 0.5-1 part of composite heating powder, 0.5-1 part of quick lime, 98-99 parts of aggregate and 0.5-1 part of water; the slow cooling type asphalt mixture capable of being used for construction in winter and the preparation method of the slow cooling type asphalt mixture have the following advantages that the cooling rate is slow, and the cooling rate of a common asphalt mixture in the environment of 25 DEG C can be achieved at the temperature of-10 DEG C; the compaction temperature range is large, and the compaction of the asphalt mixture at the temperature of 115 DEG C or above can be realized; the water stability is good, and compared with the similar conventional asphalt mixture, the water stability is better; during construction in winter, the cooling rate is low, the compaction temperature range is wide, and the construction of the asphalt pavement in winter can be realized.
本发明涉及本发明涉及沥青路面技术领域，提供一种用于冬季施工的缓慢降温型沥青混合料及其制备方法。混合料包括以下重量份的原料：沥青4～6份、乳化型温拌剂0.04～0.06份、复合加热粉0.5～1份、生石灰0.5～1份、骨料98～99份、水0.5～1份；本发明的可用于冬季施工的缓慢降温型沥青混合料及其制备方法，具有以下优点：降温速率缓慢，在‑10℃温度下，可达到普通沥青混合料在25℃环境中的降温速率；可压实的温度范围大，可实现115℃及以上温度的沥青混合料的压实；水稳定性能好，相较于同类的常规沥青混合料，拥有更好的水稳定性；在冬季施工时，降温速率慢，可压实温度范围广，可实现沥青路面的冬季施工。
