Description
Technical field
The invention belongs to bituminous pavement property the field of test technology, and in particular to electricity after a kind of splitting of bitumen mixture specimen
Fixture is collected in magnetic self-healing certainly.
Background technique
Bituminous pavement is in other factors such as reflection cracks by long-term traffic load, temperature stress and semi-rigid type base
Under effect, the diseases such as crack, loose will be generated.And existing asphalt pavement conserving and rehabilitation polymer material, such as waterproofing agent drip
Green regenerative agent etc. can influence maintenance costs and the use on road surface to some extent.But due to bituminous pavement has self-healing
Ability can repair asphalt concrete pavement by low temperature, fatigue and base by self-healing with self-healing, bituminous pavement at normal temperature
The diseases such as crack caused by layer reflection is loose, therefore the service life of asphalt concrete pavement can be improved, reduce supporting for road surface
Shield and reparation, bring the benefit of economy and traffic etc..But since self-healing speed is very in its natural state for bituminous pavement
Slowly, and require the ringing of external not traffic load, when the binder in asphalt in the intermittent phase by height
The repair rate of pitch can improve when warm.Because asphalt concrete pavement self-healing technology is compared with the reclamation activities such as sealant, no
It can be brought a negative impact to road surface is repaired, such as antiskid performance.Therefore domestic and foreign scholars have carried out bituminous pavement induction extensively and have added
Thermal self-healing closes technical research, and these researchs be unable to do without a large amount of laboratory experiment, also be unable to do without simulation bituminous pavement electromagnetism certainly
Incude the experimental provision of self-healing.
At present by bitumen mixture specimen cleave heal again simulate practical bituminous pavement electromagnetic induction self-healing when, pitch
By artificially collecting combination reduction test specimen original state after compound test specimen is broken, but reduction degree is not high, internal fissure and actual conditions
There is larger difference, influences the accuracy of bitumen mixture specimen spilt test result data.Meanwhile it healing again be crushed again
Circulation experiment when, complex steps are extremely inconvenient.
Summary of the invention
The collection fixture certainly of electromagnetism self-healing after being cleaved the purpose of the present invention is to provide a kind of bitumen mixture specimen, with
It solves to artificially collect inconvenient problem, while bitumen mixture specimen fixture can using after the splitting of existing bitumen mixture specimen
To achieve the effect that user does not need remover-and-replacer when carrying out Healing Experiments, simplify experimental implementation.
To achieve the above object, the invention provides the following technical scheme: a kind of bitumen mixture specimen splitting after electromagnetism from
Fixture, including middle part frame are collected in healing certainly, it is characterised in that: it is logical that the top and bottom end of the middle part frame offer rectangle
Slot, the top left and right sides of the middle part frame are connected with upper box by top torque spring and press from both sides, the bottom end or so of the middle part frame
Two sides are connected with lower box corresponding with upper box folder by bottom end torque spring and press from both sides, and the inside of the upper box folder offers frizzen
Through slot, the inside of the lower box folder offer frizzen and produce slot, and the inside that the frizzen produces slot is connected with by shaft
Frizzen.
Preferably, the inside of the upper box folder and lower box folder is fitted with heat-resisting sponge.
Preferably, the middle part frame is set as rectangular box-like structure.
Preferably, the frizzen is set as lightweight hardness glue stick.
Preferably, the inside two sides of the frizzen through slot are connected with locating rod, the end of the locating rod by shaft
It is provided with smooth differential of the arc plate.
Preferably, the side of the upper box folder and lower box folder offers torque spring installation positioning circular groove.
Preferably, the upper box folder and lower box folder are heat-resisting box body structure.
Preferably, being sticked on the inside of the middle part frame has heat-resisting sponge strip.
Preferably, one end of the top torque spring be fixed on box folder inside, the top torque spring it is another
End is fixed on the inside of the frame of middle part.
Preferably, all components of the fixture are all made of non electromagnetic induction material.
Compared with the prior art, the present invention has the following beneficial effects:
(1) present invention is realized by the design of its structure from test specimen fragment is collected, and after overcoming spilt test, is manually received
It is inconvenient to collect test specimen fragment, test specimen clast is difficult to collect, test specimen integrity degree and the not high problem of reduction degree, the present invention by fixture from
The original dimensional condition for maintaining test specimen as far as possible is collected, the original appearance of test specimen has maximumlly been restored.
(2) the present invention overcomes the molds for after the splitting of traditional test specimen, collecting broken test specimen not to take off after test specimen heating healing
The problem of can not completing spilt test when mould again.This laboratory holder has collects splitting in fact repeatedly under the conditions of not demoulding automatically
The function of testing rear test specimen clast and fragment is recycled after self-healing and does not demould spilt test, experimental procedure fast and easy, when
Between benefit it is particularly evident.
(3) present invention realizes collecting certainly for test specimen fragment by fixture, reduces pitch mixing when collecting after test specimen is crushed
The mass loss of material, test specimen integrity degree is higher, and reduction effect is more preferable, and the healing after carrying out electromagnetic heating more meets reality,
Experimental error is reduced, keeps experimental result more acurrate, accurately higher, it is poor to avoid artificially collecting effect, influences asphalt examination
The accuracy problem of part spilt test result.
