2004) requirement.
It is to prove ingot stripper in the case where not changing track plate test specimen performance, can be convenient and safe demould.Examination
It tests with identical material and ratio, at identical conditions, according to specific test process described above, has formed 8 tracks
Test specimen.Two groups each 4 are then classified as, demoulding time comparison is carried out, to prove that the ingot stripper can be convenient and safe take off
Mould；And rut test piece after demoulding is cut into girder and carries out low temperature bend test, it was demonstrated that the ingot stripper does not have rut test piece performance
It damages.
1, demoulding time compares
Demoulding time compares the one-to-one form that should take, and ingot stripper demoulding carries out simultaneously with conventional demoulding, at the end of
The demoulding time of first block of plate of both records completes remaining 6 pieces of rut test pieces according to same sequence, and the time is compared as follows table institute
Show.
3 time of table corresponds to table (S)
By table 3 it can easily be seen that when being demoulded to 4 pieces of board-like test specimens of asphalt, the time used in ingot stripper than
It is manually demolded and averagely lacks 89.5s, and ingot stripper is more safe and reliable, it is simple and convenient, do not need any demoulding equipment.
2, performance compares
Because kinds of experiments can be carried out after the demoulding of molding track plate test specimen, such as bending creep test, low temperature bend test, infiltration
Water test, construction depth test etc., wherein low temperature bend test is routine test, the meeting when evaluating mixture crack resistance at low-temperature
It is commonly used, there is certain representativeness, so selecting the good result of low temperature bend test proof ingot stripper in embodiment.
Track plate test specimen after demoulding patterning method is made into prism test specimen, the long 250mm ± 2mm of sample dimensions, width
30mm ± 2mm, high 35mm ± 2mm, across footpath 200mm+0.5mm, one piece of length, width and height are respectively the plate of 300mm, 300mm, 50mm
Block usually cleavable 6 test specimens.
When test, the size of test specimen is measured with slide calliper rule in span centre and two fulcrum sections, when the height or width of two fulcrum sections
When degree difference is more than 2mm, test specimen cancels.The width of spaning middle section is b, is highly h, takes the average value of opposite sides, accurately extremely
0.1mm。
Test specimen is placed in heat preservation in the thermostatic water bath of predetermined temperature and is no less than 45min, until test specimen temperature is 15 DEG C ± 0.5
DEG C, the distance between test specimen is not less than 10mm；Then, testing machine environmental cabinet is transferred to 15 DEG C ± 0.5 DEG C of predetermined temperature, test
Machine Liang Shi test specimen support is accurately good and sound, and fulcrum spacing is 200mm ± 0.5mm, and makes seaming chuck and push-down head rod iron keeping parallelism
And it is equidistant, fixed position；
Test specimen is taken out from thermostatic water bath, symmetrical immediately to place on the support, test specimen up and down direction should be with specimen molding
Shi Fangxiang is consistent.Then it being connect using load transducer, LVDT sensor with data system, is displacement with X-axis, Y-axis is load,
It returns to zero after the suitable range of selection, is finally tested with the speed of 50mm/min.
Because the test specimen number that one group of test specimen repeats test is no less than 3, to keep data more convincing, battery of tests test specimen
4 girders are selected, and numbers tested with same steps respectively.Test evaluation index is bending tensile strength (MPa), maximum curved drawing
Strain (με), stiffness modulus (MPa).Test result is as shown in the table:
4 bend test result of table
As shown in Table 4, the bend test items result of the test specimen obtained after ingot stripper demoulding will be better than conventional knocking
The test specimen that release method obtains.The experimental results showed that after being demoulded using ingot stripper, the test specimen quality of acquisition more preferably, institute
It is more accurate to obtain test result.Again because only changing stripping means, other external environments, human factor, examination during test
It is all identical to test the influence factors such as material and instrument, but from table can primary data have apparent difference, pushed away according in specification
The maximum flexural-tensile strain evaluation index recommended is it is found that the rut test piece crack resistance at low-temperature after being demoulded using ingot stripper is stronger.Therefore
It can illustrate that the ingot stripper in the present invention influences track after little or even ingot stripper demoulds to the board-like test specimen performance of asphalt
The performance of test specimen is better than manually demolded, this is because the ingot stripper, which is avoided, vehicle occurs due to tapping bottom plate for a long time and being demoulded
The case where internal structure damage of rut test specimen, so that test result is more accurate.
In summary, a kind of track die trial of the invention and ingot stripper, not only efficiency is obvious, convenient and safe, and demoulds
Rut test piece performance afterwards is more nearly reality, so that test result is more accurate.
