Description
Technical field
The present invention relates to the patching material of road, the asphalt of particularly cold construction asphalt pavement material and the manufacture method of asphalt.
Background technology
The pavement material that existing asphalt roads is used mainly contains two kinds of hot-mix asphalt mixture and Emulsified Asphalt Mixture.Hot-mix asphalt mixture is with petroleum pitch, mineral aggregate, powder etc. by a certain percentage, fries to mix with asphalt mix equipment in factory and makes.The timely then hot-mix asphalt mixture with heat is transported to the working-yard, repairs the asphalt roads road surface.But whole process all needs close traffic.Emulsified Asphalt Mixture is that emulsified bitumen, mineral aggregate, powder etc. are mixed and made into Emulsified Asphalt Mixture by a certain percentage, after Emulsified Asphalt Mixture is used to repair road construction, after must waiting for the emulsion breaking in the Emulsified Asphalt Mixture, the ability open to traffic generally needs to wait for 3～5 days.More than two kinds of materials all must disposable using, can not use next time again, in the construction in case of raining, just can not use after material is caught in the rain.Emulsified bituminous materials can not be used for the maintenance of large-area construction and high grade pavement in addition.Moreover hot mix asphalt material and emulsified bituminous materials only are suitable for temperature construction in higher season, and in temperature lower winter, just very inconvenient during construction, even can not construct.Therefore, the maintenance to road just is subjected to many-sided restriction.
Summary of the invention
In view of above-mentioned, the object of the present invention is to provide a kind of easy construction, quick, the close traffic not of constructing, free from environmental pollution, be suitable for various geography and temperature condition, the cold repairing asphalt mixture and the manufacture method thereof of the manufacturing asphalt pavement material that can store.
Cold repairing asphalt mixture of the present invention has the content of following composition and weight part meter thereof:
Heavy oil 0.45～3.6
C5 or C9 petroleum resin 0.135～2
C1, C2, C3, C4, C5, C6, C7, C8, C9, C10 solvent oil 0.9～6
In any one
Styrene-butadiene rubber(SBR) 0.18～1.6
Diesel oil or kerosene or gasoline 1.875～7
Thermoplastic styrene butadiene rubber 0.6～1.6
Naphthenic oil 0.1125～0.8
RC-10 mineral oil 0.0225～0.2
Bi tumenf orr oad 22.5～68
Mineral aggregate 920～970
Above-mentioned heavy oil: the auxiliary product of oil, have certain volatility and workability, also have certain seepage force, be used to come the swelling petroleum resin, make its fully swelling, be easy to processing, heavy oil itself contains a spot of bituminous matter in addition, therefore can combine with pitch better.
Above-mentioned C5 or C9 petroleum resin: have certain ductility and hardness.Molten molten petroleum resin have very strong cohesive force, thereby make this cold repairing asphalt mixture have certain extensibility, cohesiveness and intensity.
Above-mentioned C1, C2, C3, C4, C5, C6, C7, C8, C9, C10 solvent oil: be a kind of dispersion liquid, itself have very strong reactivity.Volatile under the normal temperature, be used for dilution and decompose styrene-butadiene rubber(SBR), the processing of being convenient to this cold repairing asphalt mixture is synthetic.
Above-mentioned styrene-butadiene rubber(SBR): have strong cohesive force, in order to improve the ductility of cold repairing asphalt mixture.
Above-mentioned diesel oil, kerosene or gasoline: be used for decomposing and the swelling thermoplastic styrene butadiene rubber, be convenient to processing, itself is volatile in addition again, makes this cold repairing asphalt mixture have good workability.
Above-mentioned thermoplastic styrene butadiene rubber: be macromolecular elastomer, have strong cohesive force and elasticity, and plasticity, thereby make this cold repairing asphalt mixture have good soft property and snappiness, increase the deformability of cold repairing asphalt mixture.
Above-mentioned naphthenic oil: be used to destroy the molecular structure of thermoplastic styrene butadiene rubber and styrene-butadiene rubber(SBR), make the body of the molecule formation graft copolymerization of this cold repairing asphalt mixture, under the effect of external force, dispersion agent comes off again, recovers the deformability of cold repairing asphalt mixture.
Above-mentioned RC-10RC-10 mineral oil: commodity, 20 ℃ of cetane value 50.2, viscosity 6.7 seconds, ash content 0.923%, flash-point remain silent 66 ℃, sulfur-bearing 0.19%, acidity 6.5, condensation point-10 ℃, existent gum 68.Used as stabilizers makes each molecular structure of forming keep the stabilization of certain period, thereby makes this cold repairing asphalt mixture have quite long period of storage.
Above-mentioned bi tumenf orr oad: have extremely strong cohesiveness, when making asphalt pavement material, play the bonding mineral aggregate, give the technical characteristics such as penetration degree, ductility, softening temperature of cold-patch compound simultaneously.Bi tumenf orr oad is by " bi tumenf orr oad technology " requirement among the JTJ052-2000 " highway engineering pitch and asphalt testing regulation ".
