Compared with the prior art, by adding the fiber and the plasticizer into the emulsified asphalt mixture to which the cement is added, the purpose of improving flexibility of the cement emulsified asphalt mixture is achieved; meanwhile, the requirement for quick opening to traffic of construction is met; in addition, amphoteric oxide, the cement, the fiber and the plasticizer in the emulsified asphalt mixture can ensure quick opening to traffic; meanwhile, properties such as road surface strength, flexibility and water damage resistance are given into consideration.
Description
Technical field
The invention belongs to emulsified asphalt technology field, specifically, relate to a kind of Emulsified Asphalt Mixture and preparation method thereof.
Background technology
Emulsified bitumen is without the need to heating; can the characteristic of normal temperature construction overcome that traditional hot asphalt wastes energy, contaminate environment and mix and stir the easily aging shortcoming of medium pitch; meet the idea of development of modern society's save energy, protection of the environment, become the Main way of road pavements development from now on.Emulsified bitumen had been widely used in maintenance of highway pavement maintenance in recent years, as the cold regeneration construction of micro-surface area, slurry seal and asphalt.Also there is a lot of problem in emulsified bitumen in construction application, and such as stability in storage too official post emulsion preserves difficulty; Cause stone surface to wrap asphalt membrane inequality with building stones mix inequality and affect Pavement Condition; Shaping speed too slowly can not open to traffic etc. fast, and these problems seriously govern the large-area application of emulsified bitumen.
Xylogen amine and quaternary ammonium salt emulsifier better performances, synthesis cost is low, and it is strong that prepared emulsified bitumen has stability, and with building stones mix, wrapping the advantages such as even, is the cationic emulsifier kind comparatively commonly used.Two kinds of emulsifying agents belong to positively charged ion and split type emulsifying agent slowly, can ensure that building stones and emulsified bitumen have sufficient duration of mixing, but the shaping speed of corresponding Emulsified Asphalt Mixture is comparatively slow, cannot meet the requirement of quick open to traffic, especially xylogen amine emulsifying agent, shaping speed is slower.Cement joins after in cationic emulsified bitumen, with gather materials mutually dispersed, bitumen emulsion wraps up cement granules rapidly, cover the surface gathered materials, the water generation hydration reaction that cement and external adding water and emulsified bitumen breakdown of emulsion are separated out, promote that Emulsified Asphalt Mixture is shaping, within the specific limits with the increase of cement mixing content, shaping speed is also in increase.In addition, hydrated product and asphalt membrane intert and interweave, and form space multistory network structure, and hydrated product fills the space after emulsion Piao breakdown of emulsion, make compound more closely knit, thus performance is more stable.
But the flexibility adding membership weakening compound of cement, makes road surface easily produce crack.Intermediate oxide adds after in Emulsified Asphalt Mixture system, even with aggregate blending, and along with the evaporation of moisture, the acid concentration of system increases, and reacts with intermediate oxide, thus accelerates the breakdown of emulsion of emulsified bitumen.Up to the present, by adding cement, setting accelerator, fiber, softening agent, rapid hardening cement and intermediate oxide to accelerate Emulsified Asphalt Mixture shaping speed with open to traffic quick in satisfied construction, and improve the rarely seen report of method of compound intensity and water resistant damage performance.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the emulsified bitumen of a kind of excellent property, constructability
