4 base joint grouting glue mix-design orthogonal arrage of table
1, modifying function of the silane coupling agent to nano silica base joint grouting glue:
(1) by Fig. 1-Fig. 4 and table 1 it is found that nano silica, which is added, can make the cone of base joint grouting glue compared with common base joint grouting glue
In-degree reduces, and softening point increases, and elastic restoration ratio is also obviously improved, and cryogenic tensile result meets code requirement, is added and is modified
It is higher to become viscosity for base joint grouting glue after nano silica.It can tentatively judge that nano silica can promote the high and low of base joint grouting glue
Warm nature energy, developing broad extrusion base joint grouting glue with it has feasibility.
(2) amido functional group silane resin acceptor kh-550 is silane coupled compared with epoxy functionality to the promotion of base joint grouting glue performance
Agent KH-560 is more significant, and wherein fluidity is substantially reduced compared with KH-560, and softening point is significantly raised, illustrates it to the raising cementation of fissures
The high-temperature behavior of glue has a clear superiority, and with the increase of KH-550 dosage, more obvious to the castering action of base joint grouting glue performance.
Through comprehensive analysis, final choice KH-550, modifying agent of the silane coupling agent that volume is 10% as nano silica.
2, influence of the modified manometer silicon dioxide volume to base joint grouting glue basic performance
(1) by figure 5-8 it is found that with nano silica volume raising, cone penetration, the elastic restoration ratio of base joint grouting glue
Decline, slamp value are remarkably decreased, and softening point increases, and illustrate that nano silica volume is higher, high-temperature behavior is better, viscosity
It is higher, but volume is greater than after 20%, and indices variation is unobvious, primarily determines the modified Nano two for being 20% with volume
Silica carries out subsequent dynamic temperature rheological experiment.
(2) according to table 2, data analysis is carried out by software and is known, when level of significance α=0.05, two groups of data are without significance difference
It is different, it was demonstrated that the modified manometer silicon dioxide base joint grouting glue of processing does not isolate, and storage stability is met the requirements.
3, influence of the modified manometer silicon dioxide to base joint grouting glue Acclimation temperature range (wide area)
Consider the actual road state of base joint grouting glue, selects dynamic shear rheometer (DSR) that load condition can be comprehensively considered
Influence with temperature to cementitious matter performance carries out thoroughly evaluating to the dynamic mechanical property of base joint grouting glue.To detect modified Nano two
Silica base joint grouting glue adapts to big this feature of the temperature difference, which is divided into high temperature group and middle low temperature group, probes into environmental Kuznets Curves respectively
The experiment parameter of temperature modified manometer silicon dioxide base joint grouting glue and common base joint grouting glue under the conditions of high temperature range and middle low temperature range
Rule passes through the high temperature of these Parameter analysis modified manometer silicon dioxide base joint grouting glues and the dynamic mechanical of middle low temperature, evaluation
Its Acclimation temperature range.
(1) table 3 is through analyzing determining DSR experiment parameter.The experiment parameter of high temperature group selects storage modulus G1, loss mould
G2, multiple viscosity η *, experiment parameter of the Rutting parameter G*/sin δ as evaluation high-temperature behavior are measured, G* is that material repetition is shear-deformable
When drag overall measurement, it be made of elasticity (can restore) part G1 and viscosity (irrecoverable) part G2, and δ be it is elastic with it is viscous
Property deformation quantity relative indicatrix, δ is smaller, and for material closer to elastomer, G*/sin δ characterizes binder resistance to permanent deformation
Ability.Under the conditions of design temperature is very high, G*/sin δ is the bigger the better.
The Rutting parameter of high temperature group is then changed into tired factor G* × sin of low temperature in evaluation by the experiment parameter of middle low temperature group
δ represents antifatigue cracking performance.G* × sin δ is bigger, shows that the energy loss under Repeated Loading is more.Studies have shown that drip
Energy loss during the fatigue damage of green mixture or fatigue life and CYCLIC LOADING has proportionate relationship.Therefore, smaller
G* × sin δ numerical value represent preferable fatigue behaviour.Multiple viscosity characterization base joint grouting glue resists internal flow under dynamic external force
Resistance characterizing, high temperature group answers viscosity and is the bigger the better, and middle low temperature group is then the smaller the better.
(2) high temperature group dynamic mechanical is analyzed
As shown in Figure 9, with the increase of test frequency, the energy storage of base joint grouting glue, loss modulus are also increased, in high frequency item
Ability of (low-temperature condition for representing glue) the modified manometer silicon dioxide base joint grouting glue with outstanding shearing resistance shear deformation under part, and
Under low frequency (hot conditions for representing glue), the non-deformability of the modulus of modified manometer silicon dioxide base joint grouting glue and common base joint grouting glue
It is similar.
The multiple viscosity η of modified manometer silicon dioxide base joint grouting glue and common base joint grouting glue*Curve is similar, illustrates nano silica
The multiple pasting parameter of base joint grouting glue is not directly affected.
Modified manometer silicon dioxide base joint grouting glue Rutting parameter integrally meets with frequency with the trend increased, and controls temperature and get over
Low, Rutting parameter is bigger, and the Rutting parameter of modified manometer silicon dioxide base joint grouting glue compares same frequency at a temperature of 35,50 DEG C of control
Common base joint grouting glue be higher by very much, and under the conditions of 65 DEG C, 80 DEG C, Rutting parameter is slightly above general silica base joint grouting glue.It says
Bright modified manometer silicon dioxide can significantly improve the anti-rut behavior of base joint grouting glue under the conditions of high temperature, in hot conditions
Lower performance is slightly promoted.
As shown in Figure 10, base joint grouting glue E1, E2 is reduced, the loss modulus E2 of modified manometer silicon dioxide with the raising of temperature
More synthermal common base joint grouting glue is much higher, shows after modified manometer silicon dioxide is added, improves the stickiness of base joint grouting glue, significant to increase
Add its loss modulus, but temperature is higher, the castering action of loss modulus is more unobvious.Therefore improved silica can promote high temperature
Under the conditions of base joint grouting glue stickiness.
The multiple viscosity η of base joint grouting glue*Decline with the raising of control temperature T.Modified manometer silicon dioxide under synthermal fills
The multiple large viscosity for stitching the common base joint grouting glue of multiple viscosity ratio of glue, also illustrates that it can increase the adhesive component of base joint grouting glue.
Modified manometer silicon dioxide has castering action to base joint grouting glue Rutting parameter under temperature match curing conditions, but with temperature
It increases, castering action becomes smaller.
In conclusion modified manometer silicon dioxide is concentrated mainly on the promotion of base joint grouting glue performance under Frequency effect
Under high temperature degree, slightly promoted under high temperature.Within the scope of high temperature, the energy storage of base joint grouting glue, loss modulus increase, and show resistance to deformation
Ability enhancing；Rutting parameter increases obviously, has stronger anti-rut behavior.Under temperature effect, modified nano-silica
Silicon also concentrates within the scope of high temperature degree the promotion of base joint grouting glue performance, and loss modulus, multiple viscosity increase, and illustrates which increase fillings
The adhesive component of glue is stitched, Rutting parameter has increase.Therefore modified manometer silicon dioxide can be obviously improved base joint grouting glue in high temperature degree
Dynamic mechanical in range.
(3) low temperature group dynamic mechanical is analyzed
As shown in Figure 11, modified manometer silicon dioxide base joint grouting glue is in 5 DEG C or so E1, E2 than base joint grouting glue common under same frequency
Greatly, 20 DEG C of E1, E2 are close with common base joint grouting glue.Modified manometer silicon dioxide increases base joint grouting glue under low temperature environment in explanation
Non-deformability.At 5 DEG C, modified manometer silicon dioxide increases the tired factor of base joint grouting glue, and 20 DEG C of whens increase less.Therefore
The anti-fatigue performance of modified manometer silicon dioxide is to be improved.
As shown in Figure 12, modified manometer silicon dioxide increases the storage modulus and loss modulus of base joint grouting glue at relatively low temperatures,
Multiple viscosity increases, i.e., increases the intensity of base joint grouting glue under middle low temperature, deformability is weaker.The tired factor becomes with the reduction of temperature
Greatly, modified manometer silicon dioxide makes the tired factor of base joint grouting glue become larger, and anti-fatigue performance is weaker under low temperature.
In conclusion modified manometer silicon dioxide is similar to high temperature group to E1, the effect tendency of E2, η * of base joint grouting glue, and
Both greater than common base joint grouting glue can illustrate that the parameter property of modified manometer silicon dioxide base joint grouting glue has continuously at different temperatures
Property, viscosity is also very high at low temperature, and the more common cementation of fissures of low temperature ductility is weak.
(4) base joint grouting glue Acclimation temperature range overall merit
It is analyzed by the Parameter Variation of the base joint grouting glue to high temperature group and middle low temperature group, finds modified manometer silicon dioxide
Dynamic property of material under high temperature to be significantly better than that common base joint grouting glue, especially viscosity are high, Rutting parameter is big, illustrate in actual height
The problems such as application can effectively reduce cementation of fissures gum softening, thawing, trickling, track in warm environment, especially continuous high temperature environment.And its
Viscosity, the tired factor are still big compared with common base joint grouting glue under cryogenic, and ductility can decline, so 20% modified Nano
Silica volume can weaken the ductility of base joint grouting glue, and viscosity is excessively high.But this can not illustrate the more common base joint grouting glue of its cryogenic property
Difference is needed by higher intensity and biggish deformation, but the two can not be same for material because of good low-temperature resistance material
Shi Zeng great.The intensity of modified manometer silicon dioxide base joint grouting glue is high, and deformation is relatively small, and cryogenic tensile has also reached standard, can
To illustrate that it has good applicability under the conditions of lower temperature, and it can be made to obtain more by adjusting material mix proportion
Good cryogenic property.In general, this base joint grouting glue can be effectively applied to annual range of temperature or the big area of day and night temperature, have higher
Intensity and longer service life.
(4) optimum mix is determined
A, raw material select
In conjunction with existing research achievement, selects No. 90 matrix pitches, rubber powder, SBS, SBR, softening agent, light stabilizer, prevents always
8 kinds of agent, modified manometer silicon dioxide materials prepare base joint grouting glue.
B, Orthogonal Parameter is analyzed
1. quadrature factor and horizontal analysis
Many research surfaces, optimum amount of the SBR in rubber asphalt are 3%, and the Optimum of softening agent is 7%, light
Stabilizer and aging inhibitor dosage all very littles, the two mainly influence base joint grouting glue ageing properties, and different SBS, nano silica,
Rubber powder dosage can significantly affect the service performance of base joint grouting glue, therefore, using pitch as basic material, rubber powder dosage, SBS dosage,
Nano silica dosage is analyzed as three factors.
Under high-temperature condition, difference between matrix pitch and rubber asphalt and the rubber asphalt of a variety of volumes it is obvious that
The volume of rubber powder is bigger, and the viscosity of pitch is bigger, and complex modulus is bigger, and the ability of resistance to deformation is stronger, but excessively high rubber powder volume meeting
The mobility of base joint grouting glue is influenced, general rubber powder volume is not more than 20%, in conjunction with existing experimental result, rubber powder volume selection 10%,
15%, 20% 3 kind of level.
SBS volume is higher, and base joint grouting glue high-temperature behavior is better, and SBS volume can get preferable effect generally between 4~6%
Fruit, therefore, SBS volume select 4%, 5%, 6% 3 kind of level.
The experimental results showed that nano silica volume less than 4%, does not make significant difference to base joint grouting glue performance, volume is more than
15%, cementation of fissures gel consistence significantly improves, mobility decline, therefore, for the wide feature of adaptive temperature range, selects nano-silica
SiClx volume selects 5%, 7.5%, 10% 3 kind of level.
2. orthogonal experiment index analysis
Base joint grouting glue Performance Evaluating Indexes have cone penetration, elastic restoration ratio, slamp value, softening point, additionally need to pass through low temperature
Stretching experiment.
Mobility experiment gained slamp value all very little, is less than 2mm more, and slamp value is as unit of 1mm, the data obtained area
Indexing not enough, so orthogonal design index should not be used as, therefore selects three cone penetration, elastic restoration ratio, softening point indexs to make
For orthogonal design objective (orthogonal arrage is shown in Table 4).
C, selection is most preferably matched and is compared
By table 4 and consider the wide requirement of adaptive temperature range, through comprehensive consideration, selection is most preferably matched and compared are as follows: rubber powder:
SBS: modified manometer silicon dioxide: SBR: softening agent: matrix pitch: light stabilizer and anti-aging agent=15%:6%；7.5%:
3%:7%:60.5%:1%.
