Description
Technical field
The invention belongs to ground surface material fields, and in particular to a kind of high resistance to compression anti-rut agent of bituminous highway.
Background technique
Asphalt pavement rut is one of primary highway disease of road traffic, it is that bituminous pavement is made repeatedly in car load
Under, runway generates biggish permanent deformation at wheelpath, and is formed on bituminous pavement along vehicle heading
A kind of shape similar to groove pavement damage phenomenon.The generation of track disease is usually in high temperature season, and asphalt surface course is in vehicle
Roll lower generation permanent deformation repeatedly and VISCOUS FLOW gradually forms.Road traffic now largely implements unidirectional row
It sails, has particularly speeded up the formation of track disease.The track disease serious curtailment service life of road, reduces the service of road
Quality, and great security risk can be brought to traffic safety: the flatness as influenced road surface reduces the safety of driving；
It is easy ponding in track slot, easily high speed traveling is caused to break away, there are huge hidden danger；The formation of track leads to road surface overall structure
Unevenly, so as to cause integral strength reduction, other derivative road surface damages are easily led to.
Anti-rut agent is a kind of multi-component chemical products, it is added by a certain percentage can in pitch or its mixture
To significantly improve the shear strength or ability of anti-deformation of bituminous pavement, to effectively prevent or delay the generation of track.At present
Widely used anti-rut agent is broadly divided into inorganic and organic two major classes.Glass fibre, diatomite etc. are main inorganic modified
Agent, and organic modifiers are then based on polyethylene (PE), vinyl-vinyl acetate copolymer (EVA), butadiene-styrene rubber (SBR) etc..
Inorganic anti-rut agent, into the gap for gathering materials skeleton, enhances the skeleton function of asphalt structure by filling embedded squeezing,
Make it is even closer between mixture, thus reduce molding road surface permeability thereby reduce the track extent of damage.Organic is anti-
Rut agent is since the micro-crystallization area that polymer is formed has comparable intensity, and part wire drawing is fine at plastics during mix
Dimension, then crosslinking puts up a bridge and forms big network-like structure, therefore enhances the adhesive force of asphalt and aggregate, strengthens pavement structure
Globality, and have the function of that certain elasticity is restored.
Anti-rut agent softens, the thermoforming in roller compaction process of these particles due to the effect of high temperature in the construction process,
The skeleton function for increasing asphalt structure strengthens the interaction force between mixture, makes between mixture more
Closely, the permeability on molding road surface is reduced.The ability of asphalt bearing load is increased simultaneously.Due in anti-rut agent
The micro-crystallization area that polymer is formed has comparable stiffness, and part wire drawing is at plastic optical fibre during mixing and stirring for it, in the bone that gathers materials
It puts up a bridge in frame and is crosslinked and forms fiber and steel bar reinforced effect.Due to the presence of polymer fiber, it forms netted, reinforcement in cementitious matter
The interaction of asphalite arogel ramming material system and globality.
Common anti-rut agent product can significantly improve mixture anti-rutting all using polyethylene as major ingredient on the market at present
Can, it is easy to use, but price is all more expensive, and the economic benefit is not high.In addition product low temperature resistance is poor, easily in low temperature
Embrittlement phenomenon is generated under environment, compressive property is also poor.To in the difficulty for virtually increasing rescue and relief work and personnel escape.
Therefore, a kind of crushing resistance and the strong anti-rut agent of mechanical property need to be researched and developed.
Summary of the invention
The technical problems to be solved by the invention: for the compressive property and mechanical property after current common anti-rut agent effect

(1) present invention carries out alkali leaching to conch meal, ultrasonic wave dispersion improves and reduces its reunion, and improves the activity on its surface,
Surface is carried out with titanate coupling agent again to be modified, and is improved the contact angle on its surface, the function and effect of itself and glue etc. is improved, to fibre
It ties up in plain acid solution oxidation processes, so that the upper part carbonyl of molecular structure is converted into carboxyl, and carboxyl and itself is included
Hydroxyl can generate compression double electric layer in system, make the suspended particulates loss of stability in latex, and occur with oxycellulose
Absorption, and suspended particulates is made to increase rapidly and settle, meanwhile, a small amount of metal inorganic salt of addition is electric in solution system
From metal ion is generated, lotion double electrical layers can be destroyed, and then accelerate gathering for active constituent, be scattered in anti-rut agent base
Material, can play toughened and reinforced effect, and when use plays dispersion pressure, reduces deformation, reduces the effect that track generates, addition
The ingredients such as gellan gum, suspension can crosslink under the action of terephthalaldehyde, and three-dimensional crosslinked network is formed in system, and
Terephthalaldehyde molecular weight is larger, and the cross-linked network hole of formation is relatively large, to be conducive to make emulsion particle stable dispersion
In three-dimensional crosslinked network gap structure, and in the curing process, along with the reduction of moisture, emulsion particle is due to mutual point
It is changed into dense accumulation state from state, can be improved internal mechanical property effect, and more fine and close cross-linked network can be formed
Network further increases effect of resist compression；
(2) present invention pre-processes talcum powder using poly-vinyl alcohol solution and surfactant, can make talcum powder table
Face organises, and reduces and increases because of the hydroxyl isopolarity group content on its surface, caused by surface texture is unstable shows
As, and cause easily there is a phenomenon where reuniting, and the special adsorption through cetyl trimethylammonium bromide, so that its interlamellar spacing obtains
To effectively widening, convenient for dispersing the effect of external pressure, is conducive to subsequent anti-rut agent base-material and other ingredients enter talcum powder
Internal structure, on the other hand, the solidification process of constituent part is exothermic reaction, and volume expands, and makes talcum powder interlayer knot
Structure is further widened, and uses gelatin, Gluten etc. for raw material composite auxiliary material, so that it has the function of cation and anion exchange and excellent
Different absorption property improves the compatibility between other ingredients, and has good viscoelasticity, can security system stability, association
The compressive property after anti-rut agent effect and the mechanical property inside pitch can be improved in same-action, and the present invention imitates Rut resistance resistance to compression
Fruit improves significantly, is worth of widely use.
