Emulsified asphalt early-strength high-toughness in-situ cold recycling mixture and preparation method thereof
The invention discloses an emulsified asphalt early-strength high-toughness in-situ cold recycling mixture and a preparation method thereof. The preparation method comprises the following steps: S1, determining the optimal mixing water content S of the asphalt reclaimed material; s2, determining the evaporation residue content of the high-viscosity modified emulsified asphalt; s3, determining the dosage of the asphalt reclaimed material, the water, the high-viscosity modified emulsified asphalt and the early-strength organic demulsifier; s4, sequentially adding water, high-viscosity modified emulsified asphalt and an early-strength organic demulsifier into the asphalt reclaimed material, and mixing; the optimal total water amount of the emulsified asphalt early-strength high-toughness in-situ cold-recycling mixture is the product of the mass of the asphalt recycled material and the optimal mixing water content S. According to the present invention, the cold-recycled asphalt mixture with characteristics of rapid early strength formation and large initial strength can be prepared, and the problems of low utilization rate of the asphalt recovery material in the traditional engineering, slow early strength formation and insufficient initial strength of the prepared cold-recycled asphalt mixture are solved.
本发明公开了一种乳化沥青早强高韧型就地冷再生混合料及其制备方法。制备方法包括以下步骤：S1、确定沥青回收料的最佳拌合含水率S；S2、确定高粘改性乳化沥青的蒸发残留物含量；S3、确定沥青回收料、水、高粘改性乳化沥青和早强型有机破乳剂的用量；S4、在沥青回收料中依次添加水、高粘改性乳化沥青和早强型有机破乳剂，进行拌合；所述乳化沥青早强高韧型就地冷再生混合料的最佳总水量为沥青回收料的质量与最佳拌合含水率S的乘积。本发明可以制备出一种早期强度形成快，初期强度大的冷再生沥青混合料，解决了传统工程中沥青回收料的利用率较低，且制备得到的冷再生混合料具有早期强度形成慢，初期强度不足的问题。
