Embodiment 2
Fig. 1~3 are please referred to, the present embodiment provides a kind of pavement structure interlayer to bond torsional test method, this method
The pavement structure interlayer introduced using embodiment 1 bonds torque test device 100, there is provided easy to operate, the reliable scene of measurement
Quantitative measurment mode.This method comprises the following steps：
S10：Drill core drill bit is drilled into structure bed boundary 211 to be measured under road surface 200, lifts drill core drill bit and obtains
To road surface core sample 220, road surface core sample 220 keeps connecting by structure bed boundary 211 to be measured and road surface 200.
Drill core drill bit and the structure of road surface core sample 220 have been described in embodiment 1, and details are not described herein again.Supplementary notes
, road surface core sample 220 keeps connecting by its end (structure bed boundary 211 i.e. to be measured) and road surface 200, makes measurement
As a result it is more true, close to the actual bearer state of road structure, avoid in traditional shearing test, sample is single after being separated with workpiece
Solely sample is carried out to test caused systemic drift error.
Preferably, S10 further includes step S11：
Lifting drill core drill bit after obtaining road surface core sample 220, cleaning road surface Xin Yang220 surfaces are simultaneously allowed to completely dry.
In other words, with the surface of water-washing method cleaning road surface core sample 220, the debris such as floating grain, soil are enable to remove, road surface core sample 220
Circumferential direction and road surface 200 between there is preferable gap, avoid interfering test process.After cleaning with absorbent material (such as
Cotton etc.) surface moisture of road surface core sample 220 is absorbed, Quick-air-drying is carried out with equipment such as hair-dryers immediately, avoids road pavement
The component of core sample 220 interferes destruction, ensures that test result is accurate.
S20：Road surface core sample 220 is bonded by the side surface of binding agent and metal substrate 110 away from the first bolt 111
Cure.Binding agent is spread evenly across between the upper surface of road surface core sample 220 and the lower surface of metal substrate 110, ensures fully patch
Close and bond.Wherein, the species of binding agent is very much, including the type such as epoxy resin A, B glue or foundry work glue caking agent.When binding agent fills
Divide after curing, road surface core sample 220 is completely fixed with metal substrate 110, forms integral force structure.
It should be noted that during whole load test, there is foot between road surface core sample 220 and metal substrate 110
Separation does not occur therebetween and loosens, avoids interfering test process destruction for enough adhesion strengths, guarantee.Meanwhile to protect
Card binding agent fully cures, it is preferable that when the hardening time of binding agent is small no less than 24.
Preferably, the outer contour of metal substrate 110 is identical with the outer contour of road surface core sample 220, metal substrate 110 and road surface
Core sample 220 it is coaxial distribution and the two outer contour it is overlapping, guarantee test moment of torsion uniformly transfers effect.
S30：Sensor unit 120 is locked by screw shell 130 and the first bolt 111, glues pavement structure interlayer
The assembling shaping of torque test device 100 is tied, is ready for the test of next step.It should be appreciated that S30 also can it is preposition in S20 it
Before, i.e., pavement structure interlayer, which bonds torque test device 100, to be to complete assembling before adhesive solidification.Certainly, S30 is placed on
Benefit after S20 can be avoided in outdoor solidification process, and torsion sensor 121 is subject to the accidental destruction of outdoor environment, is ensured
The measurement accuracy and service life of torsion sensor 121.
S40：Apply test torque and uniform load in test load input terminal 123a, until road surface core sample 220 and road surface
200 separation or road surface core sample 220 are broken, and sensor unit 120 measures corresponding test torque and obtains torsional shear moment pole
Limit initial value.
In other words, during the test, equably increase the numerical value of test torque, be close to critical torque value.Accordingly
Ground, the torsional shear square of road surface core sample 220 also move closer to utmost carrying ability.Until road surface core sample 220 separated with road surface 200 (i.e. in
Structure bed boundary 211 is broken) or road surface core sample 220 when being broken, the torsional shear square that road surface core sample 220 is born, which reaches, to be held
The limit is carried, sensor unit 120 measures test torque at this time, this is torsional shear moment pole limit initial value.
S50：Repeat above-mentioned steps and at least measure multiple torsional shear moment pole limit initial values three times, calculate multiple torsional shears
Moment pole limits the arithmetic mean of instantaneous value of initial value and obtains torsional shear moment pole limit final value, so as to exclude the drift error of single measurement, ensures
Measurement accuracy.
Preferably, if the difference between any two torsional shear moment pole limit initial value is more than threshold value, this two are remeasured
Torsional shear moment pole limits initial value.Wherein, threshold value is the default tolerance of user, for excluding to deviate excessive error interference.It is default to hold
Difference is set according to the constituent of road surface structare layer 210, for the deviation range in zone of reasonableness.In an exemplary reality
Apply in example, threshold value 10Nm.When difference is more than threshold value, show that measurement error exceedes default tolerance, which not examines
The step of considering, should re-executing S10-S40 is remeasured.
According to this method can on-site measurement torsional shear square limiting value, and provide with amendment design for site operation necessary
With reference to guidance.For example, Fig. 4~5 are please referred to, can accurate judgement permeable layers pitch sprinkling amount according to the extreme value of torsional shear square
With the relation between torsional shear square, adhesive property or other indexs between improvement road surface structare layer 210 make guide.
In all examples being illustrated and described herein, any occurrence should be construed as merely exemplary, without
It is that therefore, other examples of exemplary embodiment can have different values as limitation.
It should be noted that：Similar label and letter represents similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined, then it further need not be defined and explained in subsequent attached drawing in a attached drawing.
Embodiment described above only expresses the several embodiments of the present invention, its description is more specific and detailed, but simultaneously
Therefore limitation of the scope of the invention cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection model of the present invention
