Description
Technical field
The invention belongs to pavement material regeneration fields, and in particular to a kind of Cold Recycled Mixture with Emulsified Asphalt and its system
Preparation Method.
Background technique
In the prior art, Cold Recycled Mixture with Emulsified Asphalt is generally by emulsified asphalt, (the recycling road surface drip of RAP salvage material
Green material), cement, the room temperature such as filler mix and stir it is obtained, during mix-design, for the cold recycled asphalt for obtaining maximum dry density
Mixture needs be added except emulsified asphalt, mixes a certain proportion of Free water, and cold regeneration mix moisture content is dripped by emulsification
Water and the Free water being additionally incorporated is combined to codetermine in blueness, the intensity of cold regeneration mix and its moisture content are closely related, with
Emulsified asphalt demulsification, moisture evaporation, cold regeneration mix intensity gradually increases, therefore, the early strength of cold regeneration mix
There is correlation with conditioned time, to shorten conditioned time, usually mix 0.5~2% cement, basic principle is to pass through cement
Hydration, improve the early strength of cold regeneration mix, but strong by the early stage that incorporation cement improves cold regeneration mix
Degree has limitation, on the one hand, the excessively high mixture anti-shear ability that will cause of cement mixing content is insufficient, for anti-shear performance demand
Higher section is not suitable for；On the other hand, the raising that cold regeneration mix early strength is realized by incorporation cement, due to cement
The reasons such as volume improve limitation, and the current cold regeneration mix conditioned time for mixing cement is up to 7~8 days, cannot be practical
Solve the problems, such as that cold regeneration mix conditioned time is longer, the too long popularization and use for being unfavorable for this technology of conditioned time.
In addition, the phenomenon of the generally existing durability difference of current cold regeneration mix, emulsified asphalt cold renewal mixes according to investigation
Durability and its voidage, the bitumen content etc. for closing material are closely related, due to the voidage model of Cold Recycled Mixture with Emulsified Asphalt
Enclosing is 8~12%, under the voidage range, is easy to produce power water pressure, damages to cold regeneration mix durability, because
This, the congenital durability of cold recycled asphalt mixture is insufficient.To improve its durability, a certain proportion of regenerative agent is usually mixed, is led to
The effect for crossing pitch in regenerative agent and RAP salvage material, improves the degree of aging of aged asphalt, mixes to play and improve cold renewal
Close the effect of material durability.Such as: Chinese patent, which discloses CN103254652A and discloses, a kind of uses aromatic naphtha as regenerative agent pair
The method that waste asphalt mixture carries out cold renewal, wherein acquisition voidage is lower, globality using aromatic naphtha as regenerative agent
With the better cold recycled asphalt mixture of durability；But simultaneously the study found that aromatic naphtha volume is excessively high to will cause cold renewal mixing
Expect the decline of integral strength, volume is unsuitable excessively high, and recommending volume range is 0.1~1%, therefore, changes using aromatic naphtha merely
The limitation of kind cold regeneration mix durability.Chinese patent discloses 102174267 A of CN and discloses a kind of bitumen regenerant
And preparation method thereof, it is disclosed that by machine oil, naphthenic oil, aromatic naphtha, furfural oil any one or more, anti-aging agent, it is ultraviolet
Light absorbers, the asphalt cold recycling agent of reinforcing agent and reinforcement curing agent composition, by first preparing asphalt cold recycling agent, according still further to
It is 1%~2% addition asphalt cold recycling agent with waste asphalt weight concrete ratio, available adhesion strength is high, high-temperature behavior is good,
The excellent asphalt-regenerating mixture of crack resistance at low-temperature, actual life was up to 8 years；But it is new without being added in this technology
Pitch, the bitumen aggregate ratio of asphalt-regenerating mixture determines that a small amount of bitumen regenerant is mixed by the bitumen aggregate ratio of reclaimed asphalt pavement
Enter, only improve the ageing of asphalt degree in reclaimed asphalt pavement to a certain extent, aging improvement is mixed and stirred degree, mixed
With the multiple factors shadow such as time, uniform mixing, reclaimed asphalt pavement degree of aging, reclaimed asphalt pavement degree of crushing
It rings, difficulty of construction is high, and technical effect stability is poor, and the not applicable section required with high bitumen aggregate ratio uses, meanwhile, this skill
For art using petrochemical industries tailings such as machine oil, furfural oil as raw material, raw material variability is big, is unable to accurately control, and causes to drip
The problem of green regenerative agent stability difference, to sum up, this technology is not suitable for large-scale promotion.
