Abstract
A road interface binder and a preparation method thereof belong to the technical field of road building material manufacture, and comprise polymer modified asphalt, rock asphalt, tackifying and reinforcing resin, coupling agent and the like, wherein the components in percentage by weight are respectively as follows: 83-96% of polymer modified asphalt, 2-10% of rock asphalt, 1-6% of tackifying and reinforcing resin, 0.2-1.0% of coupling agent, and the sum of the weight percentages of the components is 100%. The preparation method comprises the following steps: the preparation method comprises the steps of inputting liquid polymer modified asphalt into a preparation tank with a heating device, controlling the temperature to be 170-185 ℃, starting a stirrer, slowly adding rock asphalt, sequentially adding a coupling agent and tackifying and reinforcing resin, and continuously stirring for 20-40 min to enable the rock asphalt to be fully mixed and react to obtain the asphalt. The invention has reasonable formula design and can effectively improve the bonding strength of the interfacial bonding material and the surface of the cement concrete.
Description
Technical field
The present invention relates to a kind of pavement interface binding material and preparation method thereof, belong to the manufacturing technology field of pavement construction material.
Background technology
The Economic development and the technical progress of society have promoted large quantities of construction of striding river, bridge spanning the sea and urban viaduct.Wherein, greatly part is done the road surface that bridge floor, upper strata bituminous concrete are done to mat formation layer for the lower layer of water cement concrete.About studying and using practice to show, whether the combination of mat formation layer and bridge floor is firm, is the important step that decision is mated formation layer work-ing life.In the present bridge construction, be enhancing the mat formation layer and the viscosifying power of bridge floor, adopt usually conducts such as emulsified bitumen binding agent, SBS modifying asphalt, bituminous epoxy mat formation layer and bridge floor between tack coat, but effect is all not ideal enough.Major cause is that the viscosity of tack coat inside is not high, and is bad with the adhesivity of cement concrete bridge deck, causes under high ambient conditions and vehicular load effect, and the layer occurred level on the interface of mating formation passed; Vertical delamination takes place on the interface because of the anti-pulling scarce capacity makes the layer of mating formation.Therefore the road surface often forms early disease.
Summary of the invention
It is reasonable to the purpose of this invention is to provide a kind of formulating of recipe, can effectively improve pavement interface binding material of interface binding material and cement concrete surface cohesive strength and preparation method thereof.
The present invention is a kind of pavement interface binding material, it is characterized in that comprising polymer modified asphalt, rock asphalt, the tackify reinforced resin, coupling agent etc., the composition of each component is respectively by weight percentage: polymer modified asphalt 83～96%, rock asphalt 2～10%, tackify reinforced resin 1～6%, coupling agent 0.2～1.0%, the weight percent summation of each component is 100%.
Described polymer modified asphalt can be the SBS modifying asphalt, itself has higher high temperature viscosity and good low temperature flexibility, as base mateiral of the present invention.
Described tackify reinforced resin can be coumarone, and main effect is to improve high temperature viscosity, thus anti-shearing, the anti-pulling ability of strongthener.
Described coupling agent can be NDZ-101 or isopropyl triisostearoyl titanate; main effect one is the consistency of contained inorganics and modifying asphalt component in the raising rock asphalt; improve the stability of binding material system; two is moistening cement concrete surface, can further improve the cohesive strength of pavement interface binding material of the present invention and cement concrete bridge deck.
The main component of rock asphalt is a bituminous matter, and its content can be more than 50%.With modifying asphalt consistency is preferably arranged, can improve the high temperature viscosity of modifying asphalt, the more important thing is that bituminous matter is strong polarity macromole, mainly in order to improve adhesivity cement concrete bridge deck.
The preparation method of pavement interface binding material of the present invention is: the input of liquid polymer modifying asphalt is had in the preparation jar of heating unit, controlled temperature is at 170～185 ℃, start agitator, slowly drop into rock asphalt and drop into coupling agent and tackify reinforced resin in succession, the lasting then 20～40min that stirs makes it fully to melt mixed and reaction makes.
The present invention compared with prior art has following outstanding advantage and positively effect:
1, formulating of recipe is reasonable: the SBS modifying asphalt that adopts relative low price and have an adhesive property is a base-material, and similar to the material character of upper strata bituminous concrete, consistency is good, and cohesive force is strong; The rock asphalt that adds strong polar compound can effectively improve the adhesivity with the lower layer of water cement concrete; Can adjust the viscosity of pavement interface binding material of the present invention according to the different interpolation of envrionment temperature tackify reinforced resin, the adding of titante coupling agent has then improved the consistency between each component of pavement interface binding material of the present invention, to strengthen the cohesive strength of self, thereby guaranteed the firm bonding of asphalt concrete pavement layer and cement concrete bridge deck, and production cost is cheap relatively.
2, different according to bridge envrionment temperature of living in height and road surface top rake size, can adjust prescription easily, make the inwardness of pavement interface binding material of the present invention and adapt with service requirements, preventing to mat formation, layer occurred level on the interface passed or the generation of vertical delamination, reaches all to prolong the bridge deck pavement purpose in work-ing life under various working conditionss.
3, a small amount of lightweight oil content evaporable flue gas that produces in the preparation process, it is clean or take high altitude discharge to introduce process furnace burning, does not have other generation of waste materials, the production process environmental protection.
Embodiment
For understanding the present invention better, proportioning, processing parameter and the salient features with 5 embodiment of the present invention is listed as follows below, further to illustrate content of the present invention.But the present invention is not limited to following embodiment, can select different proportioning and processing parameter according to the design requirements and the location weather condition of bridge, the situations such as a layer traffic loading that bears, car speed of mating formation when practical application.
