Description
Technical field
The invention belongs to highway engineering technical field, is related to a kind of asphalt cold repairing liquid and preparation method thereof.
Background technology
In China, high-grade highway use scope is wider, and what is generally used is all the structure type of bituminous paving.Pitch
Road surface compared with cement pavement, have the characteristics that the construction time is short, noise is small, ride comfort, repairing it is convenient.But bituminous paving
Under traffic load and natural environment collective effect, some diseases such as track, crack, peeling easily occur.How to these diseases
Evil road surface carries out rapid-maintenance and open to traffic is highly important as early as possible.
Cold mixing cold-application technology is a huge progress of Chinese road repair technology, but compared with American-European countries, in
State's starting is than later, and the understanding to cold repairing asphalt mixture product is derived from imported product, its research is in Introduced From Abroad product
It is inchoate afterwards.Due to external product costly, some colleges and universities and business tie-up start to carry out cold repairing asphalt mixture
Research and development.Some experts of colleges and universities start to develop cold repairing asphalt mixture and it are applied in engineering, whether exist
Research or application all have accumulated substantial amounts of invaluable experience, the rapid development of China's Asphalt Pavement Damage repairing technique, economic benefit
With environmental benefit highly significant.But the performance of China's cold repairing asphalt mixture still has the deficiency of many so far, some are crucial
Property technology is not resolved, and construction workability and initial strength there is a problem, so this just needs to be constantly working into one
Step improves cold repairing asphalt mixture.
Cold repairing asphalt mixture performance depends primarily upon asphalt cold repairing liquid, and presently disclosed asphalt cold repairing liquid patent is seldom,
General cold repairing asphalt mixture publication is relatively more, so the research and development of asphalt cold repairing liquid are most important.Asphalt cold repairing liquid is by dripping
Green grass or young crops, diluent, additive, solvent etc. are prepared under certain preparation process condition.
Asphalt cold repairing liquid usually has three types, is respectively solvent-borne type, response type and emulsified asphalt type.Prepared by response type
Mixture intensity is higher, but operating difficulties, and difficulty is brought to construction.The mixture demulsification time prepared by emulsified asphalt type is not allowed
It is easy to control, cause difficulty to storing and reaching the shaping strength time.Solvent-borne type cold repairing asphalt mixture can be under room temperature, low temperature
Storage and construction, it is on-demand from seasonal effect, save material.Temperature is relatively low in preparation and work progress, not only saves energy
Source can also reduce environmental pollution.Therefore, in terms of maintenance of surface, solvent-borne type cold repairing asphalt mixture has good prospect.
Domestic common cold repairing additive has two kinds of an external import and self-control, external product superior performance, but expensive,
It is not readily available, often construction workability and initial strength can not balance mixture prepared by Domestic Additives very well, and water is stablized
Property and cohesiveness are poor.
Asphalt cold repairing liquid is to be prepared by pitch, diluent, additive under certain preparation process, it is main former
Reason be by adding diluent, improving the workability of cold repairing asphalt mixture, in use, as diluent volatilizees,
The strength of materials strengthens, water stability enhancing.Therefore the asphalt cold repairing liquid prepared will have a good water stability, workability and strong
Degree will be got well, and just can guarantee that the performance that asphalt cold repairing liquid has had.
The content of the invention
To achieve the above object, the present invention provides a kind of asphalt cold repairing liquid and preparation method thereof, solves in the prior art
The problem of asphalt cold repairing liquid construction workability and initial strength can not balance very well, water stability and poor cohesiveness.
The technical solution adopted in the present invention is asphalt cold repairing liquid, according to mass fraction, by 100 parts of matrix asphalt,
7~15 parts of 20~35 parts of diluent, 2~4 parts of Styrene-Butadiene-Styrene Block Copolymer, additive compositions.
Further, the diluent is 0# diesel oil.
Further, the additive by 2~4.5 parts C5C9 copolymer resinses, 2~4.5 parts of ethene-vinyl acetate is total to
Polymers, 2~4.5 parts of solvent, 0.5~0.8 part of antistripping agent composition.
Further, the solvent is oleic acid.
Further, the antistripping agent is PM-JL-06A type asphalt anti-stripping agents.
Another technical solution of the present invention is that the preparation method of asphalt cold repairing liquid, follows the steps below：
Load weighted matrix asphalt, Styrene-Butadiene-Styrene Block Copolymer, be added sequentially to by step 1
In reaction vessel, 150 ± 5 DEG C of temperature, heats and constantly stirs 0.5h with iron staff；
After the completion of step 2, step 1, reaction vessel is placed under high speed shear instrument, rotating speed 6000r/min, when shearing reacts
160 ± 5 DEG C, shear time 1h of vessel temp, step 2 whole process utilize electric furnace, thermometer temperature control；
After the completion of step 3, step 2, reaction vessel is taken out, after closed, is put into baking oven, 150 ± 5 DEG C of temperature, insulation
Time 0.5h, prepared by modified pitch completes；
C5C9 copolymer resinses, ethylene-vinyl acetate copolymer, be placed in reaction vessel by step 4, and is placed on constant temperature and is
2h in 150 ± 0.5 DEG C of baking oven, takes out reaction vessel, is directly added into solvent and antistripping agent and stirs evenly, be prepared into addition
Agent, additive are in yellow, viscous；
Step 5, by the modified pitch of preparation, be cooled to 135 ± 5 DEG C additive and diluent it is placed in the vessel, will be anti-
Container is answered to be placed under high speed shear instrument, rotating speed 4000r/min, 80 ± 5 DEG C, shear time 20min of reaction vessel temperature during shearing,
Asphalt cold repairing liquid is prepared using electric furnace, thermometer temperature control in step 4 whole process.
Further, the step 2 high speed boxshear apparatus model：LDGJQ—Ⅱ.
The beneficial effects of the invention are as follows a kind of asphalt cold repairing liquid and preparation method thereof is provided, the life of asphalt cold repairing liquid is reduced
