Description
Technical field
The utility model is related to a kind of slide measure, particularly a kind of asphalt compaction test special vernier caliper.
Background technology
When asphalt uses compacting process shaping test piece, test specimen hits after reality terminates and to measure height of specimen to evaluate test specimen
Whether cancel, and adjust the mixture quality of next test specimen accordingly.Current method is that examination is first measured with common calliper
The height of mould 9, then measure respectively after the height of suitable for reading from the die trial 9 and lower mouth of test specimen 8, height (the height of specimen H of calculation testing piece 8
=die trial height h1- test specimens are from open height h2- test specimens in die trial from open height h3 under die trial), die trial, the structure of test specimen are shown in Fig. 1.
The height for calculating a point in this way is accomplished by using vernier caliper measurement three times, and the time is longer, and process is cumbersome, while root
Theoretical according to accumulated error, the resultant error calculated by three measurement results is also larger.And the column examination of asphalt
Part only calculates the height of a point generally without representativeness, generally requires the true height for calculating four points highly to judge test specimen
Degree.It can be seen that, there is pendulous frequency using common calliper measurement height of specimen many, time length, the problem of error is big.
Utility model content
In order to solve many pendulous frequencies in existing bitumen mixture specimen measuring method, time length, the problem of error is big, this
Utility model provides a kind of new survey tool, and a point only needs measurement once, and accurate examination can be directly obtained without calculating
Part height.Test period is saved, operating efficiency is improved, while reducing the error of measurement result.
The technical solution adopted in the utility model is：
A kind of asphalt compaction test special vernier caliper, including main scale, vernier and two lower measuring jaws, the main scale
Provided with the vernier that can be slided along main scale, scale is respectively equipped with main scale and vernier, respectively close to main scale and vernier zero graduation
One end of line sets lower-left measuring jaw and bottom right measuring jaw；Respectively left correcting block and right school are oppositely arranged on lower-left measuring jaw and bottom right measuring jaw
Positive block, when left correcting block and the close contact of right correcting block, vernier zero graduation line is overlapped with main scale zero graduation line.
Further, the left correcting block and right correcting block are shaped as cylinder, cuboid, square or polygon prism
Body, cylinder, cuboid, square or multiedge cylinder are connected with a bottom surface with lower measuring jaw.
Further, the radical length of the left correcting block and right correcting block is 1-2cm, a diameter of 1- of such as cylinder
2cm, cuboid, square, a diameter of 1-2cm of multiedge cylinder bottom surface circumscribed circle.Radical length is excessive to be unsuitable for many of test specimen
Point measurement；Radical length is too small, correcting block is injected the asphalt softened after heating, influences the accurate of measurement result
Property.
Further, left correcting block is consistent with the size shape in the face that right correcting block is in contact, and complete when being in contact
Overlap, left correcting block and right correcting block can so contacted and more fits, more closely, so that measurement result is more accurate.
Further, left correcting block and right correcting block is highly consistent, because test specimen in theory is away from the upper and lower open height of die trial
Difference should not be too big, therefore, left correcting block and right correcting block it is highly consistent when be more conducive to direct measurement to test specimen.
Further, the height of left correcting block and right correcting block is 1.5-2.5cm, is matched with the size of test specimen, die trial.
Further, the distance between left correcting block and right correcting block and main scale are 1.5-3cm, with test specimen, the chi of die trial
Very little matching.
The beneficial effects of the utility model are, the utility model by left and right two correcting blocks respectively directly with test specimen
Upper and lower surface contact, is not required to measure the height of suitable for reading from the die trial and lower mouth of test specimen respectively, and also avoiding the need for calculating directly can just obtain
Go out result, therefore, it is possible to save test period, improve operating efficiency, missed while reducing pendulous frequency and also just reducing measurement
Difference.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain this
Utility model, is not used to limit the utility model.
