Abstract
The invention relates to star-shaped modified emulsified asphalt and a preparation method of the star-shaped modified emulsified asphalt in the field of a building technology. The star-shaped modified emulsified asphalt contains the components in percent by weight: 3-5% of arene, 3-8% of modifier, 2-5% of emulsifier, 1-3% of reinforcer, 3-10% of solubilizer, 20-50% of water and 30-60% of heavy-traffic asphalt. The preparation method includes the steps: firstly, conducting the following operations as follows: A. stirring the arene with the solubilizer, then adding the modifier and conducting stirring; B. adding the emulsifier and the reinforcer in water and then conducting stirring; C. heating the heavy-traffic asphalt; and secondly, mixing the products obtained from the A, B and C operations in the step 1 simultaneously, and then enabling the mixture to pass through a colloid mill, thus obtaining the star-shaped modified emulsified asphalt.
