Description
Technical field
The invention belongs to road pavement Material Field more particularly to a kind of preparation methods of asphalt warm-mix agent.
Background technique
Asphalt used in previous road engineering is generally divided into two types according to mix construction temperature: cold mixing drip
Green mixture CMA(Cold Mix Asphalt) and hot-mix asphalt mixture HMA(Hot Mix Asphalt).Cold-mix asphalt is mixed
Material is closed generally using emulsified asphalt or liquid asphalt and gather materials mix, making under normal temperature state, without to gathering materials and combine
Material is heated, and can save mass energy in this way.But cold-mix asphalt mixture early strength is lower, it is difficult to it is public to meet high speed
The requirement of the important engineerings such as road, Heavy Traffic road.Hot-mix asphalt mixture be widely used, the good mixing of pavement performance
Material.But in hot-mix asphalt mixture production process, pitch and building stones need the mix under 150 ~ 180 DEG C of hot conditions.Disappear
The a large amount of energy is consumed, meanwhile, the mix under hot conditions also easily causes pitch and heat ageing occurs, and reduces pitch on road surface
Active time shortens the service life of bituminous pavement.To extend the bituminous pavement service life, the prosperities such as later period the 1990s America and Europe
Country has carried out the research of warm-mixed asphalt technology.Warm-mixed asphalt technology be a kind of mix temperature between hot asphalt technology (150 ~
180 DEG C) and cold-mix asphalt technology (10 ~ 40 DEG C) between, performance reaches the pitch mixing section of (or close) hot-mix asphalt mixture
It can new technology.Usual warm mix technology is most common to be achieved in that addition warm-mixing agent, warm-mixed asphalt technology and standard hot asphalt
It compares, temperature can reduce 20 ~ 30 DEG C.Warm-mixed asphalt technology has many advantages: reduction bituminous mixture and construction first
Temperature, can be with 20% or more energy saving；Asphalt storage temperature reduces simultaneously, the mobility enhancing under lower temperature；Separately
Outside, extend the asphalt pavement construction phase, expand application range.
There are three types of most common asphalt warm-mix agents: organic matter warm-mixing agent, chemical warm-mixing agent and foam warm-mixing agent.Organic matter temperature
Mixing agent is usually paraffin, fatty acid amide etc.；Chemical warm-mixing agent is usually emulsifier and polymer etc.；Foam warm-mixing agent is will to lack
Amount water, which is added in pitch, forms foam, to reduce the viscosity of pitch, to achieve the purpose that reduce mix temperature.
CN101602862A discloses a kind of warm-mixed asphalt additive and preparation method thereof, which is by the way that deionized water to be added
Into the polyvinyl alcohol water solution being made into advance, rosin quaternary ammonium salt, aromatic hydrocarbon quaternary ammonium salt emulsifier, aliphatic hydrocarbon are then sequentially added
Quaternary ammonium salt emulsifier, anionic surfactant, stirring and dissolving, then by the polyacrylamide solution being made into advance and three second
Hydramine is added, and mixing to is finished product after being uniformly dissolved.The additive can be substantially reduced pitch and mix and stir temperature, and pitch is mixed
It closes and expects that every pavement performance index also complies with requirement, but the additive component is complicated, increases the difficulty and cost of preparation, no
Conducive to practical application and low-temperature cracking-resistance reduces；CN102268189A discloses a kind of warm-mixed asphalt additive and its preparation side
Method, it is in dicyandiamide solution using a kind of additive of organic silicon modified by polyether polymer composition.It can be effectively reduced and mix and stir
40 DEG C of temperature or so, and warm-mixed asphalt low-temperature cracking-resistance is not less than hot asphalt, but lacks relevant test method and instance number
According to support.Therefore researching and developing a kind of pitch, crack resistance remains unchanged good warm-mixing agent at low temperature, it is quite necessary to.
