Description
Technical field
The present invention relates to a kind of bituminous compositions and preparation method thereof, particularly a kind of road modified asphalt group
Close object and preparation method thereof.
Background technique
Pitch has good mineral adhesive force and viscoplasticity and is widely used in laying road.The variation in season is to drip
Green pavement performance influence is very big, and when temperature is high, pitch easily melts and easily trickling.On the contrary, pitch is easier to become when temperature is low
It is crisp, so as to cause pitch lost flowability.This property often makes bituminous pavement occur track phenomenon at summer, in winter
Asphalt pavement warm contracting cracking.With the rapid development of China's economic, the increase of road Traffic Volume, the road surface that traditional pitch is paved into
It can no longer meet the demand of development, therefore, pitch be modified, improve its pavement performance, to meet different evils
Use demand and the demand growing to high quality road asphalt under bad environment.
And the selection of asphalt modifier to the road of modified pitch with and service performance play deciding factor.Modified pitch is
Modifying agent is added in matrix pitch, such as outer-penetrating agents such as rubber, high molecular polymer or other fillers, or is taken light to pitch
The methods of degree oxidation, is made the asphalt binder that performance is improved.
Asphalt modifier can be generally divided into two class of polymerbitumen modifying agent and non-polymeric asphalt modifier.Chinese patent
CN101717585A discloses a kind of emulsified SBS polymer modified asphalt and preparation method thereof, use raw material for matrix pitch,
Water, SBS asphalt modifier, composite asphalt emulsifier, emulsion stabilizer and hydrochloric acid first heat matrix pitch, and SBS pitch is added
Modifying agent after stirring swelling, by colloid mill high speed grinding and fully dispersed, obtains SBS modified pitch after heat preservation development；In water
Middle addition composite asphalt emulsifier, is added the emulsion stabilizer mixed well in advance with water, and addition appropriate hydrochloric acid adjustment pH value obtains soap
Liquid；Finally SBS modified pitch is cooled down, is mixed with soap lye and obtains emulsified SBS polymer modified asphalt through emulsion dispersion.It is suitable for
Adhesion coating, sealing, top dressing, slurry seal and asphalt pavement regeneration, warm-mixed asphalt, the passenger dedicated railway line plate of road construction
Cement asphalt mortar layer of formula track etc..Chinese patent CN106810884A discloses a kind of changing based on graphene anti-rut agent
Property pitch by matrix pitch and accounts for the weight percent of the matrix pitch and is made of the graphene anti-rut agent of 1%-7%；Wherein
Due to the interface interaction of graphene, so that matrix pitch and anti-rut agent effective component form rock-steady structure.CN102051060A
Disclose a kind of inorganic modified coal pitch and preparation method thereof, using the preparation of this modified coal pitch carbon pole used for aluminium electrolysis and
TiB2/ C composite cathode material, bulk density, compression strength, bending strength, inoxidizability, anti-electrolysis expansion character have bright
It is aobvious to improve.
Single use polymer is all limited to asphalt modification effect in currently available technology or single use is non-poly-
It closes object to be modified, but this single modifying function is limited.There is presently no the associations of the modifying agent to a variety of mechanism of modifications
Same-action is studied.It is therefore desirable to develop the bituminous composition of a kind of polymer and non-polymer modified synergic, reinforce
Comprehensive performance of pitch under the conditions of extreme weather and external force.
Summary of the invention
