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.
