Abstract
A kind of bitumen polymer modification cold mixing asphalt cold repairing and its preparation are made of bitumen, asphalt, solvent based liquid SBS, vegetable oil refining pitch, liquid cross-linker, diluent.Preparation method is that bitumen is added according to quantity in 160~170 DEG C of asphalt, after bitumen mineral particle is ground to less than 15 microns, 100 DEG C or less are cooled the temperature to after addition room temperature vegetable oil refining asphalt mixing is uniform according to quantity, solvent based liquid SBS is added, liquid TAIC is added under stirring, continue stirring and diluent is added, it stirs evenly cooling up to kind bitumen polymer modification cold mixing asphalt cold repairing, use product of the present invention, manufactured cold-patch mixture performance not only meets the requirement of specification, its Marshall intensity etc. is well beyond code requirement.Since there is bitumen the molecular weight and inner frictional resistance than common petroleum pitch bigger, the modification of crosslinked liquid SBS also to further promote the distribution that asphalt cold repairing is modified cross-linked network, being it has the performance for being better than common cold mixing cold-repairing material.
Description
Technical field
The invention belongs to highway engineering Material Fields, and in particular to a kind of cold mixing of asphalt pavement conserving pit repairing
Cold-patch cementing material, specially a kind of bitumen polymer modification cold mixing asphalt cold repairing and its preparation.
Background technology
Had been used for many years using the cold mixing cold asphalt mixture for diluting common petroleum pitch as road, Rapid-Repair not by
Weather condition influence is its advantage, but its cohesive strength is small to be also apparent disadvantage.
Invention content
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of the present invention is a kind of bitumen polymer modification cold mixing is cold
It mends pitch and its preparation is made using bitumen macromolecule, the heteroatomic strong cohesive property of polarity using solvent based liquid SBS
For polymer modifiers, and asphalt is modified by liquid cross-linker crosslinking, according to cold mixing cold-patch common petroleum road
The cold mixing cold asphalt mixture that a kind of intensity is high, cohesive force is big, caking property is good is made in the way of road pitch.
To achieve the goals above, the technical solution adopted by the present invention is：
A kind of bitumen polymer modification cold mixing asphalt cold repairing, which is characterized in that by quality parts ratio include consisting of：
Bitumen：10~50 parts,
Asphalt：40~60 parts,
Solvent based liquid SBS：5~10 parts,
Vegetable oil refines pitch（Residue）：5~10 parts,
Liquid cross-linker：0.1~0.3 part,
Diluent：5~10 parts.
The bitumen is the mixture of lake asphalt, rock asphalt or the two, and mixed proportion is lake asphalt：Rock asphalt
=0~10：10~0.
The solvent based liquid SBS, use dry rubber content for 40~60% solvent based liquid SBS.
The vegetable oil refining pitch is to produce the residue refined after C5, C6 chemical products using agricultural product stalk etc..
The liquid cross-linker is liquid triallyl fulminuric acid fat（Liquid TAIC）.
The diluent is~No. 10 diesel oil, No. 0 diesel oil or aviation kerosine.
The asphalt is commercially available A grades of bi tumenf orr oad.
A kind of preparation method of bitumen polymer modification cold mixing asphalt cold repairing, which is characterized in that include the following steps：
Composition dispensing is matched according to product quality number, bitumen is added according to quantity in 160~170 DEG C of asphalt, is ground
After bitumen mineral particle is milled to less than 15 microns, after room temperature vegetable oil refining pitch is added according to quantity, after stirring evenly
100 DEG C are cooled the temperature to hereinafter, solvent based liquid SBS is added, it is dilute to continue stirring addition by the addition liquid TAIC under stirring
Agent is released, is stirred evenly cooling up to kind bitumen polymer modification cold mixing asphalt cold repairing.
The beneficial effects of the invention are as follows：
Using product of the present invention, manufactured cold-patch mixture performance not only meets the requirement of specification, and Marshall intensity etc. is significantly
Beyond code requirement.Since bitumen has the molecular weight and inner frictional resistance than common petroleum pitch bigger, crosslinked liquid
The modification of SBS also further promotes the distribution that asphalt cold repairing is modified cross-linked network, and being it has better than common cold mixing cold-repairing material
Performance.
Specific implementation mode
