Description
Technical field
The invention belongs to road traffic technical field, more particularly, to a kind of high osmosis permeable layers emulsified asphalt and its preparation side
Method.
Background technology
Highway in China is many, and with semi-rigid material as basic unit, it acts on self-evident as the main supporting course of pavement structure,
Believe also to have within a period of time from now on and quite apply on a large scale.Good between semi-rigid type base and bituminous paving for ensureing
The good method coupling, taking sprinkling priming oil on semi-rigid type base all the time, this is solve the loose problem of interlayer one
Item important technical.Asphalt pavement of highway at this stage typically uses cement stabilized macadam, lime stabilization rubble or Calx
The making semi-rigid type base such as flyash stabilization gravel, as the primary load bearing structure of road.After Construction of semi-rigid base often
It is carried out with health preserving of sprinkling water, promotes its intensity to be formed.If to substrate surface timely spread priming oil before making bituminous paving,
So that Colophonium is penetrated into basic unit, fill its hole, combine to form film coating with gathering materials of substrate surface, pin basic unit's moisture, then may be used
Play the purpose of basic unit's water conservation health preserving.Meanwhile, the water resistant scouring capability of basic unit also can be improved, and extraneous infiltration is made to basic unit
The destruction becoming necessarily is reduced, and therefore, permeable layers as an important feature layer between semi-rigid type base and asphalt concrete pavement are
Requisite.Can permeable layers penetrate into basic unit's certain depth, to enhancing basic unit globality, and forms basic unit and bituminous texture layer
Good combination be requisite.Permeable layers are located at substrate surface it is desirable to penetration depth is more than 5mm, make the half of inorganic binder
Rigid base is progressively transitioned into the asphalt surface course of organic binder.The penetration depth of permeable layers is to be influenced each other by many factors, phase
Mutually restriction it is necessary to find out essence and the feature of these influence factors, could select well, apply antireflective material layer, real rise
To layer coupling transitional function.China's reason construction is often to increase basic unit's cement, lime dosage, directly contributes substrate surface excessively
Densification, priming oil is difficult to down ooze.The history of priming oil application during review China recent decades constructing road, overview is got up
Layer oil product kind mainly has：(1) coal tar, for permeability, coal tar is a kind of more satisfactory priming oil material to list.With
The development of coking industry, the many effective ingredient in coal tar are refined in a large number as industrial chemicals, especially coal tar itself

1.1.2 the production of emulsified asphalt
Stabilizer was added in soap lye before producing emulsified asphalt.Specifically addition manner is：Formula by emulsified asphalt
Add emulsifying agent, stabilizer respectively in water, after to be emulsified dose is all completely dissolved with stabilizer, then pH is carried out to emulsifying agent soap lye
Value is adjusted.
Emulsified asphalt is only to use one of process form, and after breakdown of emulsion, work is the property of Colophonium, therefore I
Wish that oil-water ratio is the bigger the better, can reduce the input of production equipment so while guaranteeing asphaltic nature, reduce transport
Expense, but also have a problem that simultaneously, and that is, oil-water ratio is big, and emulsified asphalt viscosity is big, affects its permeability.Specification regulation is used
Asphalt Emulsion Evaporation Residue content in priming oil should be greater than 50%, it is considered herein that this regulation is not proper, it is true that in reality
The priming oil bitumen content using in the engineering of border rarely reaches more than 50%.Bitumen content is big, and permeability is little, easily ties on surface
Skin, is so equal to the oil mass that increased bottom surface layer, and basic unit is also affected with the combination effect of bottom surface layer, therefore, saturating
During coating emulsified asphalt produces, asphalt content is 45%.
Fixing bitumen content prepares emulsified asphalt for 45%, by through verification experimental verification it is determined that emulsifying agent optimum amount.
Substantial amounts of test shows, when the consumption of emulsifying agent is less than this optimum amount, the poor storage stability of emulsified asphalt.Table 4 is test
Result.

The DVAP BIT CL-92 of Rhodia, Henan Luohe in anionic emulsified bitumen in cationic emulsified bitumen
After JLA01 produces, just there is agglomeration a period of time, increases the consumption of emulsifying agent nor is improved, does not carry out next step
Test.Other emulsifying agents, production process is all very smooth.
A certain amount of stabilizer is all added in the production process of permeable layers emulsified asphalt.Including inorganic stabilizers and organic
Stabilizer.Because the solid content of emulsified asphalt is relatively low, only 45%, such as it is added without stabilizer, the storage stability of emulsion can not
Reach requirement, the phenomenon of layering easily occurs.The addition of stabilizer is precisely in order to ensure the storage stability of emulsified asphalt.
Inorganic stabilizers are primarily referred to as inorganic salts compound.Inorganic salt except reduce surface tension in addition to, also with formed
The size of emulsion droplet, interface charge, the viscosity of emulsion, oil-water interfacial film has very big relation.It is present in emulsifier solution
Inorganic salt, the surface activity of solution can be made to improve.The impact to nonionic emulsifier for the inorganic salt is less.When increase aqueous solution
Ionic strength when, the athletic meeting of powered Colophonium microdroplet is limited by bigger, thus add ionogenic inorganic salt permissible
Improve emulsion intercalation method.The substance of general cationic emulsifier has CaCl2, MgCl2, NH4Cl, FeCl3Deng.And for
Anion emulsifier, then to add NaCl, Na2SO4, Na3PO4Deng based on.In the present invention, mainly add in cationic emulsifier
Plus material has：CaCl2, MgCl2And NH4Cl；In anion emulsifier, main substance has：NaCl, Na2SO4And Na3PO4.Add
Dosage is respectively 0.2%, 0.4%, 0.6%.Result of the test shows：The addition of inorganic stabilizers, can improve emulsified asphalt
Lamination during storage, but still the requirement of specification can not be met, emulsified asphalt still showing of layering after 5d placement
As.Improve the addition of stabilizer, the phenomenon of layering also occurs.
Organic stabilizer is primarily referred to as organic macromolecule class compound.Being added in of organic stabilizer is formed on particle surface
The adsorption layer of macromole, thus prevent the coalescence between particle.As effective stabilizer, macromolecule stabilizer must have two
Individual feature：On the one hand there is very strong affinity, to be firmly adsorbed on particle surface with particle；On the other hand again with
Solvent has good affinity, to be fully extended in strand, forming thick adsorption layer, reaching the mesh protecting particle not coalesce
's.Common macromolecule stabilizer has：Polyoxyethylene, polyacrylic acid, polyisobutylene, polyvinyl alcohol, cellulose derivative etc..And
It is applied to the stabilizer of emulsified asphalt system, conventional has polyvinyl alcohol, methylcellulose, Sodium Tvlose etc..For
Anionic emulsified bitumen, select in research is Sodium Tvlose；For cationic emulsified bitumen, select in research is
PVAC polyvinylalcohol 17-99.Result of study shows, the addition of organic stabilizer can improve the storage stability of emulsified asphalt, 0.2
～0.4% addition can play vital effect.Add organic stabilizer emulsified asphalt place 5d after still
Can keep not stratified, not sink to the bottom.
1.1.3 permeable layers emulsified asphalt performance indications
Table 5 permeable layers emulsified asphalt performance indications
1.1.4 permeable layers emulsified asphalt permeance property test
Permeable layers emulsified asphalt pavement performance test is mainly the permeability investigating emulsified asphalt.In the present invention, first adopt
The penetration testing of Japanese specification：Add a small amount of water with 50g cement and 1000g normal sand to mix and stir, load in Marshall die trial, one side
Hit real 50 times, health preserving 7 days at ambient temperature, by the consumption of 2L/, emulsified asphalt is sprayed at cement standard sand surface.Pass through
Test determines, the optimal ratio of mud of mortar specimen is 55%.By the spread quantity of permeable layers, permeable layers emulsified asphalt is spilt on mortar specimen,
After certain time, from middle part cutting sample, measure Colophonium depth of penetration (in terms of mm).For the emulsified asphalt of energy stable existence,
Permeability test, result such as table are all carried out.

As can be seen from the table, on test specimen, anion and non ionic emulsified bitumen penetration depth, can be basic in 5mm
Meet code requirement, but cationic emulsified bitumen does not permeate substantially.Conventional engineering experience shows：Exist in a large number in China
Cement, Calx, on the semi-rigid type base of flyash class, because material has strong basicity, cationic emulsified bitumen is difficult to penetrate into,
Preferably to do penetration material using the emulsified asphalt of anionic and nonionic to use.Result of the test and conventional research experience one
Cause.
1.2 researchs being used for priming oil high osmosis emulsified asphalt
1.2.1 raw material and testing equipment
1) Colophonium
Test is shown in Table 1 from No. 90 high richness Colophoniumes of petrochina, material technology performance.
2) emulsifying agent
Previous studies demonstrated that, anion and non ionic emulsified bitumen can have good penetrating power, therefore, above
Research foundation on, have selected the preferable anion emulsifier of combination property as the basic emulsifying of high osmosis emulsified asphalt
Agent.

3) emulsified asphalt mulser, marshall compaction instrument, normal sand etc..
1.2.2 the production of emulsified asphalt
In order to reach the penetrating power of emulsification pitch penetration oil, in order to improve the penetrating power of emulsified asphalt, only lean on emulsifying
Agent itself can not be fully solved problem it is therefore necessary to from new approach.Interpolation can reduce the surface tension of emulsified asphalt,
Improve emulsified asphalt to the infiltration of basic unit and can to diffuse into the penetrating agent of basic unit be improve emulsified asphalt penetrating power one
Plant feasible method.In general, the adding mode of penetrating agent has two kinds, one kind be configuration soap lye during be previously added determination amount
Penetrating agent, then be added to the preparation carrying out emulsified asphalt in colloid mill together with hot-melt asphalt；Two is in the breast having produced
Change the penetrating agent adding determination amount in Colophonium.Compare, in first kind of way, penetrating agent and Colophonium and emulsifying agent are in colloid
Mill through sufficient shearing in mill, more preferably, performance is more uniform for dispersion effect.Therefore, the penetrating agent in the present invention be all with
The second way adds.
1.2.3 the development of Thief zone emulsified asphalt
1) determination of penetrating agent consumption
With kerosene as penetrating agent, asphalt content is 40%, fills the penetrating agent of different amounts respectively, true by permeability test
Determine the optimum amount of penetrating agent, penetrating agent consumption is respectively 6%, 8%, 10% and 12%.Find through experimental study, work as infiltration
Agent can lift the permeability of emulsified asphalt when 8%, meet code requirement, but the ratio effect of 10% penetrating agent is more excellent,
The consumption being further added by penetrating agent is not significantly improved to osmotic effect, and more can increase the cost of emulsified asphalt, therefore finally
Determine penetrating agent consumption be 10%.
2) change of penetrating agent type
Have selected three kinds of penetrating agent on the basis of previous studies, a respectively normal line oil, dichloroetane and kerosene.Through
Vinyl, from pre-stage test preferable anionic emulsified bitumen GYM-02 anionic, chooses penetrating agent consumption 10%.Test
Data is as shown in table 8.
The contrast test of the different penetrating agent of table 8
As known from Table 8, from a normal line oil and dichloroetane as penetrating agent, penetration depth also can reach code requirement
5-10mm, but osmotic effect is still not so good as relatively dilute Colophonium.A normal line oil rate of set and seepage velocity are all slow than kerosene, and two
Chlorobutane rate of set and seepage velocity are all fast than kerosene.
1.2.4 Thief zone emulsified asphalt performance indications
By research above, the Thief zone emulsified asphalt adding penetrating agent has good osmotic effect, therefore it is entered
Go performance detection.By the effect of emulsifying agent, emulsified asphalt microgranule is uniformly dispersed in water.Add the emulsifying after penetrating agent
Colophonium, granular size ratio is more uniform, does not affect the microstructure of emulsified asphalt.After placing 5d, Thief zone emulsification Colophonium goes out
The phenomenon of some particle agglomerations existing.And after 5d placed by Thief zone solvent naphtha emulsified asphalt, distribution of particles is still highly uniform.Therefore
Under identical amplification, Thief zone solvent naphtha emulsified asphalt is more uniform compared with Thief zone emulsification pitch particle.
