Description
Technical field
The present invention relates to a kind of emulsified bitumen class gap-grouting material for asphalt pavement crack sealing maintenance.
Background technology
Emulsified bitumen cementation of fissures material is take emulsified bitumen as raw material because emulsified bitumen has good flowability, can infiltrate dark and crack that size is less in, the moisture evaporation reaches the purpose that mends a split behind the breakdown of emulsion.Compare the heated bitumen cementation of fissures and repair, the emulsified bitumen cementation of fissures is repaired easier filling to the depths, crack, and need not heating, and construction is simple, and is low to workmen's technical requirements, more saves cost when reducing environmental pollution.Along with the develop rapidly of emulsified bitumen research and application, emulsified bitumen class cold-penetration seam material is widely used in repairing road cracks, and various Emulsified bitumen crack pouring materials continue to bring out.
CN1962526A provides a kind of polymer joint-grouting material for pavement, is comprised of liquid compound and dry powder blend material two portions, and wherein liquid compound main component is 85%~97% emulsified bitumen and 3~15% polyvinyl alcohol solution; Contain 76~95% alkaline powders, 1~3.5% tensio-active agent, 0.5~1% yellow soda ash and 3~20% waste rubber micropowders in the dry powder blend material, alkaline powder absorbs moisture that the emulsified bitumen breakdown of emulsion produces and aquation, plays to fill and strengthen gap-grouting material and the absorption cohesiveness of being filled with the knot body.CN101148338A has introduced a kind of environmental protection inorganic powder material and polymer composite modified emulsification asphalt grouting material; its main component has 65~75 parts of emulsified bitumens, 25~35 parts of inorganic powder materials, 10~30 parts of protective materials; utilize the strong suction of nano inorganic powder material, the performance of easily disperseing can improve concrete castability and the penetrating power of emulsification asphalt grouting material.
Above-mentioned emulsified bitumen cementation of fissures material is that emulsified bitumen is mixed with powdered material, and the moisture that absorbs emulsified bitumen by powdered material reaches quick formation intensity, the requirement of open to traffic.Not having chemical reaction between powdered material and the pitch, only is that pitch is simply mixed filling, and asphalt performance is not significantly improved.
Summary of the invention
The purpose of this invention is to provide a kind of response type inorganic active powder and strengthen Emulsified bitumen crack pouring material, wherein thereby active inorganic powder not only can absorb the moisture that the emulsified bitumen breakdown of emulsion produces and forms fast intensity, and with water reaction after the material that discharges can participate in asphalt modification, improve the softening temperature of pitch, improve the high-temperature behavior of pitch.

5In one or more.Play suction, moulding strengthens, and improves the effects such as asphalt performance.
Described response type inorganic active powder strengthens Emulsified bitumen crack pouring material, and it is prepared and uses according to following technical process:
The A component: the mixed solution of preparation emulsifying agent, stablizer, properties-correcting agent and water is also controlled its temperature in 55~60 ℃, then adopt the emulsified bitumen colloidal mill (namely to get emulsified bitumen cementation of fissures material A component behind 3000~10000rpm) processing, 1.5~2min with asphalt heating to 135~140 ℃, and with the emulsifying agent mixed solution.
B component: dispose in proportion peptizer.
During construction, on-the-spot A, the B component of evenly mixing carries out cementation of fissures construction immediately.
Required peptizer is a kind of alkaline inorganic active powder among the present invention.This material absorbs the water in the emulsified bitumen with after emulsified bitumen mixes, and hydration reaction occurs generate crystal salt, both can improve the emulsified bitumen de-emulsification speed, can guarantee that again Emulsified bitumen crack pouring material has enough flowabilities and sufficient working hour.Secondly, the reacted product of emulsified bitumen and peptizer can improve its softening temperature under the condition that does not change emulsified bitumen residue ductility, so that gap-grouting material obtains better high temperature stability performance.
Characteristics of the present invention are:
