Quick-set wheel-adhesion-free sticky layer emulsified asphalt and preparation method thereof

The invention relates to quick-set wheel-adhesion-free sticky layer emulsified asphalt and a preparation method thereof. The emulsified asphalt is prepared from the following components in percentage by total mass: 40-60% of matrix asphalt, 0.5-10% of an interface enhancer, 0.1-3% of an asphalt emulsifier, 0-3% of hydrochloric acid, 0-0.1% of a thickening agent and the balance of water. The preparation method comprises the following steps: firstly, preparing two middle materials, namely, reinforced modified asphalt and liquid soap, secondly, grinding the middle materials at a high speed so as to form unstable type emulsified asphalt; and finally stirring the unstable type emulsified asphalt at constant temperature, thereby obtaining the sticky layer emulsified asphalt. The sticky layer emulsified asphalt has the benefits of rapid demulsification speed and rapid forming, so that the construction efficiency is greatly improved; the sticky layer emulsified asphalt has the characteristic of not being adhered to tires, so that the damage of construction equipment and transportation vehicles to a sticky layer material is avoided, the adhesion efficiency and the adhesion strength are improved, and the durability of a pavement is improved; the asphalt is good in high-temperature property, is simple and practical in process and is beneficial for popularization and application.
