Description
Technical field
The invention belongs to a kind of road-making material, be specifically related to a kind of preventive maintenance mist sealing composite modified emulsification asphalt and production method of road and bridge bituminous pavement.
Background technology
Mist sealing belongs to the measure of road preventive maintenance, and it can improve road surface envelope, waterproof effect, also can seal and mend little fracture pore, can also improve the apparent property on road surface, improves the resistance of aging of road table.
Mist sealing can be divided into two large classes by use material, and one is common emulsified asphalt class; Another is containing regenerator class (solvent-borne type).And road surface multiplex greatly be all solvent type mist sealing.
Common emulsified asphalt class, emulsified bitumen is the topmost starting material of mist sealing, and mist sealing emulsified bitumen used is necessary for cation type, does not have strict requirement to emulsion breaking speed, but general recommendations is with splitting type soon, the emulsion required than common emulsified asphalt mist sealing is thinner.The residual content sieve aperture of 0.6 ㎜ on sieve.
The high temperature performance shown on road in order to pitch after improving breakdown of emulsion is stablized, usual employing SBR latex carries out modification to pitch, and SBR modifying asphalt to there is high-temperature behavior poor, so the SBS adopting high temperature performance to have both and resin compounded modifying asphalt are more better than SBR modification.Composite modified emulsification asphalt key problem in technology is the emulsification to SBS modifying asphalt, and SBS modifying asphalt is emulsified also can only be the volume of very low properties-correcting agent, and be generally 1-2%, we know, pavement performance improves along with the increase of content of modifier.Therefore how making the SBS modifying asphalt of high dosage emulsified is content of the present invention.
Summary of the invention
The object of this invention is to provide a kind of composite modified emulsification asphalt and preparation method thereof, enforcement for the measure of road preventive maintenance provides a kind of mist sealing conserving material of high quality, high-performance, again environmental protection, by the preventive maintenance process of the gauge seal layer that satisfies the need, reach prolonging service life of pavement, reduce the object of maintenance costs.
Composite modified emulsification asphalt provided by the invention, its raw material composition and part by weight as follows:
Emulsifying agent A0.5-1,
Emulsifying agent B0.5-1,
Water 98-99,

Above-mentioned emulsifying agent A adopts hexadecyl methyl bromide ammonium 1631, emulsifying agent B to adopt the condenses of OP-10 alkylphenol and oxyethane.
The preparation method of composite modified emulsification asphalt provided by the invention is:
1. emulsifying agent A, B and water are mixed and heated to by weight proportion 60-80 DEG C make the composite emulsifying aqueous solution, add hydrochloric acid adjustment pH value;
2. in the matrix pitch of the part by weight of 160-165 DEG C, add properties-correcting agent SBS, tackifier carbon five and membrane-forming agent polyvinyl alcohol by weight proportion, adjustment temperature, at 170-190 DEG C, makes composite modified asphalt;
3. again the composite emulsifying aqueous solution and composite modified asphalt are mixed and made into composite modified emulsification asphalt.
Composite modified emulsification asphalt of the present invention, to be modifying asphalt be dispersed in water formed low viscosity with molecule, high-performance, the milk sap that can meet different construction requirement are sprayed at road surface, bridge floor, has good associativity, perviousness and high/low temperature stability after emulsion breaking with contact layer.The mixing of properties-correcting agent, tackifier, membrane-forming agent join make emulsion shaping after there is higher cohesive force, dense black color.
The present invention compared with prior art has following features: formula and the preparation technology of employing are scientific and reasonable, strong with contact layer seepage force, adhesivity good, high/low temperature stability has both, and simple to operation, is more conducive to environmental protection.
The present invention is widely used in traffic, bridge deck surfaces is disposed in the engineerings such as preventive maintenance.
Performance index of the present invention are as follows:
Polymer modification emulsified bitumen indices
