Abstract
The invention relates to an intensive infiltration emulsified asphalt and its preparation, wherein the emulsified asphalt comprises (by weight percent) asphalt 30-50%, water 45-50%, emulsifying agent 0.8-2%, thinning agent 2-15%, balancing stabilizing agent and modifying agent.
Description
Technical field
The present invention relates to a kind of repairing the roads with asphalt of penetrate layer and preparation method thereof, particularly a kind of intensive infiltration emulsified asphalt and preparation thereof.
Background technology
Bituminous pavement is in construction process, asphalt of penetrate layer (being commonly called as priming oil) all must spray in all kinds of basic units, brea bed must be after asphalt of penetrate layer infiltrates through basic unit fully can making, the depth of penetration that it has been generally acknowledged that asphalt of penetrate layer is at least more than the 5-10mm, if asphalt of penetrate layer can not penetrate basic unit, only be sprinkled upon the surface and form one deck oil film, effects such as that asphalt of penetrate layer just can not play is fixed, stable, connection, waterproof, thus have influence on work-ing life of bituminous pavement.
At present, what adopts is the problem of puzzling by it on the road construction work as priming oil always.The MS-22 of Asphalt Institute only speaks of " adopt medium-curing liquid asphalt and emulsified bitumen to infiltrate and do not punish base material to enough degree of depth " to the narration of priming oil, comprises that other standard and the monograph of emulsified bitumen (MS-19) all do not have the description about the priming oil that is applicable to cement stabilized base course.Present stage, China adopted emulsified bitumen and fluxed asphalt as priming oil, and the advantage of employing emulsified bitumen does not need heating when being to use, and can spray at the normal temperature state, has characteristics such as price is low simultaneously.But because the perviousness of emulsified bitumen is relatively poor, multipotency reaches about 4mm, thereby influences the quality of bituminous pavement.Adopt fluxed asphalt to use as priming oil, because the weight ratio that it need add is a pitch: minimum 1: 1 of thinner, and mainly adopt gasoline, kerosene, diesel oil etc. to join in the petroleum pitch at present as thinner, be characterized in good penetrability, can penetrate the above degree of depth of semi-rigid type base 5-10mm, but owing to the cost of material height as thinner such as gasoline, kerosene, diesel oil, the cost when causing fluxed asphalt to use as priming oil is very high, can't popularize in China.
Summary of the invention
The purpose of this invention is to provide low relatively being used to of a kind of good penetrability, price repairs the roads with intensive infiltration emulsified asphalt and preparation method thereof.
For achieving the above object, the technical scheme of employing is:
Characteristics of the present invention are: 1, adopt dilution earlier, back emulsive production technique, under the situation that adds thinner seldom, the penetrating quality of asphalt of penetrate layer is improved greatly, can penetrate the above degree of depth of the 5-10mm of basic unit, thereby the stability that each aspect that has improved bituminous pavement connects makes to improve 3-5 the work-ing life on road surface.2, production cost reduces greatly.Because gasoline, kerosene, the weight percent of diesel oil in intensive infiltration emulsified asphalt of the present invention as thinner are significantly smaller than the amount in the fluxed asphalt, per ton cost can reduce about 800-1000 unit, if press the Grade I Road construction of national regulation, adopt this intensive infiltration emulsified asphalt to compare, every kilometer cost-saved about 18000-23000 unit with fluxed asphalt.The data presentation of being announced according to highway water transportation industry development statistical communique in 2004, increased 6.08 ten thousand kilometers calculating in 2004 newly, if employing the technology of the present invention, can reduce construction cost more than 1,000,000,000 yuan, this shows that social benefit and economic benefit that the present invention brings are very significant.3, production technique simple.Adopt dilution earlier, back emulsive technology simple process just can realize above-mentioned advantage, and is practical strong, easily promotes the use of.
Embodiment
To be that example describes as follows to produce 100 kilograms of intensive infiltration emulsified asphalts:
Embodiment one:
At first weigh the pitch 50kg that is used to build the road, add the thinner of 3kg then, after mixing by mechanical stirring, add 45kg water, 1kg emulsifying agent and 0.5kg stablizer and 0.5kg properties-correcting agent again, in bitumen emulsifying plant, carry out emulsification after, be finished product.
Above-mentioned as thinner gasoline or the additional proportion of kerosene or diesel oil can to carry out arbitrary proportion as required composite, as: gasoline: kerosene: diesel oil is 1: 1: 1, is 1kg.Also can only add in above-mentioned three kinds any one according to the geographic situation of construction.
Embodiment two:
Weigh the build the road pitch of usefulness of 30kg, add the thinner of 15kg then, after mixing by mechanical stirring, after adding 50kg water, 2kg emulsifying agent and 1kg stablizer and 2kg properties-correcting agent, in bitumen emulsifying plant, carrying out emulsification, be finished product.Thinner can be a gasoline: kerosene: diesel oil is 1: 2: 3 composite forming, also can be composite in other ratio according to practical situation.
Embodiment three:
Weigh building the road of 40kg and use pitch, add the thinner of 10kg then, after mixing by mechanical stirring, after adding 43kg water, 2kg emulsifying agent and 2.5kg stablizer and 2.5kg properties-correcting agent, in bitumen emulsifying plant, carrying out emulsification, be finished product.Thinner is a gasoline: kerosene: diesel oil is 1: 5: 1 composite forming, also can be composite in other ratio according to practical situation.
Gasoline adopts low-grade gasoline in the foregoing description, and kerosene, diesel oil can adopt the corresponding label of good fluidity according to construction seasons, as adopting-No. 10 or more low-grade diesel oil winter, adopts the diesel oil more than No. 0 summer.The selection standard of thinner mainly be when considering construction temperature and under the condition more than the penetration depth 5-10mm, reduce cost as far as possible.
Emulsifying agent can adopt asphalt emulsifier or the like product that Shanghai Jingwei Chemical Co., Ltd. produces in the foregoing description.Product or like product that pitch stablizer and properties-correcting agent can adopt High-Tech Development Zone, Jinan mountain science and trade company to produce.
In the above-described embodiments, thinner can just be used single gasoline, other working conditions and constant rate.Also can adopt single kerosene, other working conditions and constant rate.Also can adopt single diesel oil, other working conditions and constant rate.
In the above-described embodiments, thinner also can adopt the arbitrary proportion of gasoline or kerosene, gasoline or diesel oil, kerosene or diesel oil to mix, as thinner, and other working conditions and constant rate.
