Description
Technical field
The invention belongs to a kind of road-making material, be specifically related to a kind of road, the crack of bridge bituminous pavement repairs polymer modification emulsified bitumen base joint grouting glue used and preparation method thereof.
Technical background
Bituminous pavement in use stands the comprehensive action of vehicular load and physical environment for a long time, Asphalt Pavement Cracking is caused to produce crack, under the souring of water, crack can be developed to sub-surface, As time goes on, road surface easily forms the diseases such as hole groove, or even rainwater is shown to penetrate into soil matrix through crack by road, greatly weakens the strength and stability of roadbed, cause road surface to be subject to more havoc, therefore road pavement crack carries out repairing is necessary.
Current fracture both at home and abroad carries out repairing treatment and generally adopts the cream patching of the modifying asphalt cementation of fissures and emulsification asphalt grouting patching.
The patching of modifying asphalt cementation of fissures cream.Directly heated bitumen is poured into fracture in crack to repair.The normally used material of this method is polymer modified asphalt.Polymer modified asphalt is heated to 160-180 DEG C, then pours in crack, after its cooling, get final product open to traffic.
As a kind of polymer modified asphalt gap-grouting material of U.S.'s development, there is good elasticity, mobility and cohesive force, not by season and climatic influences, can stick to firmly on ditch slotted wall after joint filling, be connected with road surface, as long as product is put into during construction in a special kettle, by manually pouring in crack, repave sand, get final product open to traffic.The characteristic that gap-grouting material should possess should be that the material poured in seam all has higher elasticity under normal temperature and low-temperature condition, recoverable deformation can be there is along with the breathing in crack, remain its sealing function, compared with same kind of products at abroad, the modifying asphalt gap-grouting material of domestic production is poor at low temperature elasticity, extensibility is poor, can not adapt to the breathing in crack.External product then price is high, and equipment is complicated.
Emulsification asphalt grouting patching, be pitch heat melted with aqueous emulsion through mechanical effect, form oil-in-water bitumen emulsion, be in a liquid state under normal temperature shape.Pouring in process, emulsified bitumen infiltrates in crack, treats its breakdown of emulsion, and moisture evaporates, and reaches the object mended a split.As a kind of emulsion-type base joint grouting glue material of Singapore's exploitation, in half flow state under normal temperature.With the special injection pressure equipment construction of one, general perfusion 1-2 time, the perfusion degree of depth can reach 15-20 ㎝, but also there is the high problem of price.
Emulsification asphalt grouting method, compared with modifying asphalt cementation of fissures method, has the following advantages: emulsified bitumen is fluent material, can fill with to depths, crack and perviousness is strong; Do not need heating during construction, save the energy; Simple to operate, low to workmen's technical requirements; Environmental pollution is little, is beneficial to environmental protection.
How to obtain and all to have higher elasticity under normal temperature and low-temperature condition, along with the breathing in crack, recoverable deformation can occur, remain its sealing function, easy construction is simple again, saving the little base joint grouting glue material being beneficial to environmental protection of energy environmental pollution, is content of the present invention by said two devices unification.
Summary of the invention
The object of this invention is to provide a kind of polymer modification emulsified bitumen base joint grouting glue material and preparation method thereof, for road preventive maintenance provides the conserving material of a kind of high-quality, environmental protection, by the enforcement of the reclamation activities of fracture, reach the work-ing life namely extending road, save energy is beneficial to environmental protection again, reduces the object of maintenance costs.

Above-mentioned emulsifying agent adopts hexadecyl-methyl bromide ammonium 1631, and properties-correcting agent adopts styrene-butadiene-styrene block copolymer.
The preparation method of polymer modification emulsified bitumen base joint grouting glue provided by the invention is:
1, the preparation of aqueous emulsion: emulsifying agent and the water heating 60-80 DEG C are in advance mixed and made into aqueous emulsion according to the above ratio, adds hydrochloric acid adjustment pH value 2-4;
2, the preparation of modifying asphalt: matrix pitch is by weight proportion heated to 170-180 DEG C, adds properties-correcting agent, carbon five, polyethylene, resol by above-mentioned part by weight, starts agitator, stirs 2 hours, prepare modifying asphalt;
3, again aqueous emulsion and modifying asphalt are mixed and made into polymer modification emulsified bitumen base joint grouting glue.
Polymer modification emulsified bitumen of the present invention is the dispersion system of polymer modified asphalt in water, be dispersed in aqueous phase with molecule, the low viscosity formed, the milk sap that can meet different construction requirement pour in the crack such as road surface, bridge floor, after emulsion breaking, there is with contact layer good adhesivity, perviousness and high/low temperature stability, reach the object mended a split very well.
Performance index of the present invention are as follows:
Polymer modification emulsified bitumen indices
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; Overcome existing hot Slit-pouring Technology need heat, the weakness such as the high/low temperature poor stability of poor, the complicated operation of infiltration and common emulsified asphalt grouting technique, energy-saving and environmental protection.
