Description
Technical field
The present invention relates to asphalt pavement material preparation field, particularly a kind of salt particle for bituminous pavement ultra-thin wearing layer and preparation method thereof.
Background technology
In northern China most area, southwest plateau, mountain area, middle part, often occur that snowfall is frozen weather winter, along with highway pavement accumulated snow freezes, doughnut and coefficient of road adhesion and frictional coefficient significantly reduce, cause tyre slip, stopping distance extends, and causes sideslip, direction out of control, rollover time serious, even causes heavy traffic accident.
At present, in order to guarantee driving safety and the coast is clear, the domestic and international removing road snow mantle technology of freezing mainly contains initiatively snow-clearing technique and passive snow-clearing technique, and wherein passive snow-clearing technique mainly comprises the methods such as artificial clearance technique, mechanical removal technology, spreading sandstone material, spreading snow melt salt; Initiatively snow-clearing technique mainly contains melting snow and ice by heating power technology, building for anti-freezing technology.
Make a general survey of all kinds of snow melt clearing ice technology, according to snow melt technology operability, construction costs and persistence, chemical classes building for anti-freezing technology becomes main flow snow melt gradually and presses down ice technology, and its technological core is from snow melting material research and development, has carried out some exploratory studys both at home and abroad.
Abroad, press down ice material from snow melt and originate from Europe of the sixties in 20th century, the Dubois R flaxseed oil of Switzerland is wrapped in CaCl
2with the surface of NaOH, with Ca (OH)
2after mixing, through the technique such as granulating and forming, oven dry, prepare the particulate material of diameter at 2 ~ 7cm; 1976, during the lava that snow melting material is added to a kind of porous by the people such as Siegmund Werner gathers materials, and cause the particle of certain particle diameter, this material is joined in asphalt with the form of gathering materials, under the rolling of vehicle, abrasive action, effective snow melt composition is separated out gradually, reaches the object from snow melt; The eighties in 20th century, DOT company of the U.S. develop have fewer environmental impacts without chlorine, environment-friendly snowmelt agent-calcium magnesium acetate; It is main compound from snow melting material Verglimit that Switzerland successfully develops with calcium chloride, also known as V-260, is the chemical material that a kind of process concentrates, adds in asphalt, effectively can stop or slow down icy on road when mixing and stirring production as filler; Late 1970s, Japan starts to introduce American-European snow melt and presses down ice technology, and have developed Mafilon on this basis, also known as MFL, similar with V-260 feature; 1985, snow melt was pressed down ice Technology application in water-permeable pavement by MasuyamaYoshinari, and have developed a kind of water-permeable snow melt cement pavement; 1988, the American Terence.E.Peel LMWBL snow melting material that utilized papermaking wastewater to manufacture also was applied for a patent, and can use at extremely frigid zones, but because involve great expense, never scale operation; The snow melt that 1992 German Hoechst Aktiengesellschaft (DE) develop based on acetate presses down ice material, and it effectively becomes is the sodium-acetate of 15%-70% or Potassium ethanoate or the mixture of the two.
At home, press down ice investigation of materials from snow melt and start late, started from 2008, Introduced From Abroad presses down the MFL product of ice material Switzerland V-260 and Japan from snow melt.Subsequently, engineering technical personnel in succession develop have independent intellectual property right from snow melting material, Chang An University successfully develops a kind of salt particulate material suppressing ice/snow on road pavement to freeze, and is applied to domestic many motorways, state's provincial highway Maintenance in Winter engineering; The First Highway Survey & Design Institute of China Co., Ltd develops snow melt coating technology; A kind of New Kind of Solvent of Snow-melted jointly utilizing part ocean and plant extraction liquid to research and develop by ocean institute of the Chinese Academy of Sciences, Qingdao City's municipal administration maintenance management; Hebei University of Technology and Hebei Xuan-Da express way Management Department have developed compound snow-melting agent jointly.
Press down ice material as can be seen from domestic and international above from snow melt, normally used snow melt presses down ice material and mainly contains three classes: the first kind is that acetic acid salt presses down ice material; Equations of The Second Kind is that chloride salt presses down ice material; A class is also had to be biological extraction liquid.
In snow melt salt bituminous pavement from snow melt press down ice material mainly contain two kinds of use-patterns: the first be from snow melt press down ice material combine with high molecular weight reactive type coating material, admixture appropriate abrasion resisting type fine aggregate, is sprayed at Lu Biao and consolidation forms snow melt coating; In ice and snow season, in snow melt coating, salt effective constituent is separated out, and realizes from snow melting function.The second mixes in process at asphalt mixture heat to mix salt particle, and its particle diameter is 0.075mm, and percent of pass is generally more than 75%, and incorporation is generally 3% ~ 8%; For new pavement, the 4cm that mats formation is thick in snow melt asphalt concrete layer; For old pavement, after milling, re-pave 3 ~ 4cm is thick in snow melt asphalt concrete layer, salt is wrapped up in attached by pitch, water penetrates into from snow melting material layer from bituminous pavement space, effective constituent separates out road surfaces gradually under the effects such as osmotic pressure, capillary force and wheel " pump suction ", plays the effect that snow melt presses down ice.
In the first use-pattern, its snow melt coating needs special spraying equipment, and after application, pavement skid resistance condition generally declines, in coating only 2 ~ March in work-ing life under heavy traffic, it is attractive in appearance that residue affects road surface, and need repeatedly spray every year, comparatively large to Coherent traffic noise, construction costs is higher; In the second use-pattern, its salt particle heat is mixed in asphalt, pave-load layer is thicker, after capping salt compound effective constituent is separated out, along with top layer polishing is with closely knit, pave-load layer bottom salt is separated out slowly or is difficult to separate out, later stage snow melt effect is also not obvious, and salt particle is soluble in water, mixes in the Cold-mix such as slurry seal, micro-surface area and will run off rapidly, cannot preserve.
Therefore, for from snow melt salt bituminous pavement, solution three key issues are required: one is from snow melt salt Material composition design and optimization; It two is separate out path and slowly-releasing from snow melt salt material effective constituent; It is three for need environmental protection, economy, easy construction from snow melt salt material.
