Description
Technical field
The present invention relates to the chemical technology field of road made of new structural material, in particular to
A kind of complete molten direct putting type high viscosity property-modifying additive and preparation technology thereof.
Background technology
Along with the fast development of economic society, people's trip and living environment quality demand
Constantly upgrading.In field of road, " forth generation " Functional road-porous asphalt pavement,
Have the rainy day reduce vehicle accident, alleviate environment noise, can snow-melting and ice-breaking, reduce Urban Thermal
Island effect, elimination urban road glare are polluted and build the characteristics such as sponge city.Drainage asphalt
Road surface is universally acknowledged high security and the New Asphalt Pavement Structures of high environment fusion, tool
Have that antiskid performance is high, noise is low, the outstanding advantages such as comfortable of driving a vehicle, wet traffic accident rate can be reduced
More than 50%, monolayer reduces noise 3～5 decibels, double-deck noise 9～11 decibels of reducing,
Enjoy titles such as " top functional surfaces ", " super road " and " quiet road surface " abroad.
But " forth generation porous asphalt pavement " is high to modified asphalt technology index request.
At present, rubber powder is added in Colophonium by some R&D institution domestic, in order to pass through rubber
Rubber powder strengthens the dynamic viscosity index of Colophonium, but its dissolubility is very poor, the operation longevity to road
Life has certain negative effect.
And the SBS modified pitch of the high-load developed can cause porous asphalt pavement uneven,
And matrix pitch can not be fully compatible with polymer；And it is in engineer applied process and indoor
Prepare high-viscosity modified asphalt and exist serious inconsistent.It is to be added by modification at Practical Project
Add agent and add in asphalt mixing cylinder, the blade rotated by certain speed, and by rough set
Modifying agent softening is attached to coarse aggregate surface, a part of matrix pitch and rough set by the friction of material
Material surface forms the macromolecule membrane of liquefaction；A part exists in granular form.Through long-term
Engineering observation find, the asphalt membrane of the porous asphalt pavement of this modification easily fission cracking,
Asphalt mastic keeps the modified pitch sample that elastic ability is substantially sheared not as indoor high-speed
(technique is inconsistent to be caused).In addition, the macromolecular material existence form in modified pitch is uneven
Even, cause the porous asphalt pavement operation life-span not enough.
Meanwhile, the polyphosphazene polymer contained by high-viscosity modified asphalt prepared by " wet method " is used
Compound grinds for a long time through high-speed shearing machine, and high molecular polymer exists with micrograined texture,
This particle size is 10 μm～50 μm, and this special high-viscosity modified asphalt is in heating
And short time transportation is easy to heat polymerization, generate the polyphosphazene polymer of bulk
Compound, this method of modifying can not by stable for high molecular polymer microgranule between matrix pitch,
Certain haulage time can not be kept.
Technical staff is according to " wet method " technology both at home and abroad, has formulated with absolute viscosity 20kpa.s
High-viscosity modified asphalt standard for basis for estimation.Above-mentioned SBS modified pitch grade is
PG76-28, it can not meet porous asphalt pavement in high temperature, rainy and heavy-load road
Demand, operation the life-span only reach about 5-7.
And, existing high-viscosity modified asphalt technical specification by macromolecular material at Colophonium
Content in technical system limits.When macromolecule polymer material content is more than 8%, high viscous
Degree modified pitch is susceptible to isolation and thermal polymerization, the polymer that aggregation formation group turns.
Therefore, these so-called high-viscosity modified asphalts are for compact asphalt pavement, Zhi Nengzuo
For the modified pitch application more slightly higher than conventional modified pitch, seriously constrain " forth generation draining
Bituminous paving " development.
In order to solve the problems referred to above, rubber powder is dissolved into Colophonium by some R&D institution domestic,
Will pass through the dynamic viscosity index of rubber powder enhancing Colophonium, but the technical specifications such as its dissolubility
Undesirable, the dispersive property in asphalt is poor, is only improved modified pitch system
Index, and to run the effect in life-span undesirable for improving road.
