Description
Technical field
The invention belongs to asphalt pavement conserving fields, and in particular to a kind of high viscoplasticity for acid aggregate bituminous pavement
Gap-grouting material and preparation method thereof.
Background technique
With China's expanding economy, communication achieves the progress advanced by leaps and bounds, highway construction total kilometrage and high
Grade highway construction mileage has respectively reached the position of the first in the world and second.There is 75% to belong in the highway of China's construction
Bituminous pavement, this ratio is higher in high-grade highway, this is because bituminous pavement have good damping effect, driving it is comfortable,
The advantages that noise is low, and reparation speed adaptable to roadbed is fast.Bituminous pavement has that advantage is also defective, mainly due to dripping
The pitch that binding material is served as in green road surface belongs to organic matter, and with temperature sensitivity and there are aging phenomena, so building up
Bituminous pavement during being on active service afterwards can gradually generate disease.
Crack is that one of occur earliest in all Asphalt Pavement Damages and be prevalent in every country bituminous pavement
Disease form.U.S.'s SHRP project shows that road pavement disease carries out timely repairing maintenance and can not only improve road surface and make
Safety prolongs its service life, and is better able to save the cost of later period maintenance of surface.
For the repairing maintenance of asphalt pavement crack, lot of domestic and foreign scholar has carried out a large amount of research.The emphasis of research
Two aspect of maintenance method and conserving material is concentrated on, maintenance method mainly has: joint filling, the cementation of fissures, patch seam etc.；And main research is also
It is in terms of concentrating on conserving material, the conserving material developed at present is mainly include the following types: heat pitch class, colod-application pitch class
With functional tree lipid.There are two significant deficiency needs to overcome for this currently used three categories material: one, road surface is swollen when high temperature
Swollen, gap-grouting material is traveling vehicle since anti-extrusion difference is easily extruded crack and takes away when crack narrows；Two, road surface is received when low temperature
Contracting, gap-grouting material tensile property and adhesion property difference easily crack with sides of fracture generation again when crack broadens.
The bituminous pavement aggregate overwhelming majority of China's construction is alkaline bone material, but since regional environment and materials limitation are asked
Topic, there is also the acid aggregate bituminous pavements of a part.It is well known that containing acidic-group so it has centainly in pitch
Acidity, can form very strong chemical bond when pitch and alkaline bone material meet causes the adhesive attraction between them stronger；When
Pitch and acid aggregate not will form the stronger chemical bond of bond energy when meeting, so the adhesive attraction between them also weakens.Mesh
Preceding gap-grouting material common in the market is all blanket, and does not differentiate between acid aggregate or alkaline bone material bituminous pavement,
Lead to do not there is a kind of gap-grouting material to be specific to alkaline bone material asphalt pavement crack at present, is let alone a small amount of application, viscous
The worse acid asphalt pavement crack of attached performance, this is also that current research system lacks and urgently to be resolved, and is market
There is an urgent need to.
In view of common gap-grouting material currently on the market, there are the significant deficiencies of self-strength difference and adhesion property difference, and simultaneously
The special designing of gap-grouting material is not carried out for the characteristics of acid aggregate bituminous pavement.Present invention proposition is invented a kind of for acidity
The high viscoplasticity gap-grouting material of aggregate bituminous pavement.Such gap-grouting material is directed to acid aggregate bituminous pavement and is designed, and passes through
The polyhydroxy organic matter of addition improves the adhesive attraction with aggregate acid in bituminous pavement；Polyhydroxy organic matter can also by with
The effect of waste rubber powder and flexible adjustment agent forms elastomer.Such high viscoplasticity cementation of fissures material for acid aggregate bituminous pavement
Material while two significant deficiencies for improving common gap-grouting material at present, are a kind of pavement seam filling materials with broad prospect of application
Material.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of tool the characteristics of for acid aggregate asphalt pavement crack
Targeted high viscoplasticity gap-grouting material.Such material is capable of forming the elastomer with some strength, solves high anneal crack
The problem of gap-grouting material telescopicing performance difference when gap-grouting material anti-extrusion performance difference and low-temperature cracks broaden when seam narrows；Such material
In polyhydroxy organic matter can improve the cohesive force between gap-grouting material and sides of fracture, solve when low-temperature cracks broaden due to
The caused problem of Cracking again of adhesion property difference.
The present invention adopts the following technical scheme:
A kind of high viscoplasticity gap-grouting material for acid aggregate bituminous pavement, it is matched by following raw materials and parts by weight
Than being made:
