Embodiment Construction
[0013] The preparation method of modified emulsified asphalt of the present invention is leach method, and its specific operation process is as follows:
[0014] 1. When the temperature of the base asphalt reaches 120-170°C, put the latex of the modifier into it and stir thoroughly to make a uniform solution, wherein the latex content of the modifier is 1-50% (by weight percentage of the asphalt).
[0015] 2. Add a certain amount of emulsifier, stabilizer, water and other materials into the mixer, fully stir and mix, and control the temperature at 50-95°C to make the emulsifier content 1-10%.
[0016] 3. Mix and emulsify asphalt latex and emulsion through an emulsifier to obtain modified emulsified asphalt.

A process for preparing the modified emulsified asphalt for road pavement includes such steps as proportionally adding latex as modifier to basic asphalt, stirring, proportionally mixing with emulsifier, stirring and defoaming. Its advantages are high performance, high construction efficiency of road, and long service life.
Description
technical field [0001] The invention relates to a preparation method of modified emulsified asphalt, belonging to the technical field of asphalt emulsification and modification. Background technique [0002] The slurry seal construction technology with emulsified asphalt as the binder has many advantages such as wide application range, convenient construction, energy saving, pollution reduction, and extended construction period. However, due to the disadvantages of single base asphalt, such as strong temperature sensitivity, low viscosity, and poor flexibility, the popularization and application of slurry sealing technology is restricted. [0003] In view of the outstanding advantages of slurry seal construction technology, its popularization and application is imperative, but the problem is how to improve the performance of emulsified asphalt. That is to modify the emulsified asphalt to make it have excellent low-temperature crack resistance, high-...
