Abstract
The utility model discloses an asphalt mixture marshall experiment test mold with thickness measurement function, which comprises a large test mold and a standard test mold, wherein the large test mold and the standard test mold respectively comprise a test mold inner wall and a test mold outer wall; the inner wall of the test mold is carved with inner scales for measuring the thickness of a test piece; and outer scales for measuring the thickness of the test piece are carved on the outer wall of the test mold. The utility model provides a test the mould practicality strong, through adding the scale at marshall test mould inner wall, compare current marshall test mould, can in time accurately measure when marshall test piece shaping whether this test piece thickness meets the standard requirement, in time adjust the bituminous mixture quantity to the test piece that is not conform to the standard requirement, can guarantee to accomplish fast and relevant experimental.
Description
Technical Field
The utility model relates to a bituminous mixture marshall experiment examination mould especially relates to a bituminous mixture marshall experiment examination mould of taking thickness measurement function.
Background
In the marshall stability test of the asphalt mixture and the marshall stability test of the asphalt mixture soaking, a marshall test piece is formed by using a T0702 standard compaction method. In this method, the molded Marshall specimen is left for 24 hours and then the dimensions of the specimen are measured. If the size of the test piece is not qualified, the test piece is rejected, and the Marshall test piece needs to be formed again by using the T0702 standard compaction method and waits for 24 hours, which is very time-consuming. Therefore, it is necessary to design a test mold which can accurately measure whether the thickness of the test piece meets the standard requirement in time when the Marshall test piece is formed.
Disclosure of Invention
In order to solve the technical problem, the utility model aims at providing a take bituminous mixture marshall experiment examination mould of thickness measurement function.
The purpose of the utility model is realized through the following technical scheme:
a kind of asphalt mixture Marshall experiment with thickness measurement function tests the mould, including large-scale test mould and standard test mould, large-scale test mould and standard test mould include the inner wall 1 of test mould and test mould outer wall 3 separately; the inner wall 1 of the test mold is carved with an inner scale 2 for measuring the thickness of a test piece; and the outer wall 3 of the test mold is carved with an outer scale 4 for measuring the thickness of the test piece.
Compared with the prior art, the utility model discloses an advantage can have as follows to one or more embodiments:
the marshall experiment test mould for the asphalt mixture is internally provided with scales, so that the thickness measurement function can be realized, whether the thickness of the test piece meets the standard requirement can be timely and accurately measured when a marshall test piece is formed, and the using amount of the asphalt mixture is timely adjusted for the test piece which does not meet the standard requirement. Effectively prevents the time waste caused by the size of the test piece failing after 24 hours of placement, and can ensure that the related test is completed quickly.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
As shown in fig. 1a-3b, the experimental test model for the marshall asphalt mixture with the thickness measuring function comprises a large test model 5 and a standard test model 6, wherein the large test model and the standard test model respectively comprise a test model inner wall 1 and a test model outer wall 3; the inner wall 1 of the test mold is carved with an inner scale 2 for measuring the thickness of a test piece; and the outer wall 3 of the test mold is carved with an outer scale 4 for measuring the thickness of the test piece.
The inner diameter of the large test mould is set to be 152.4mm +/-0.2 mm, and the total height is 115 mm; the inner diameter of the standard test die is set to be 101.6mm +/-0.2 mm, and the total height is 87 mm. The inner scale of the inner wall and the outer scale of the outer wall of the large test mold range from 0mm to 115mm, and the minimum scale is 1 mm; the inner scale and the outer scale of the inner wall of the standard test mould range from 0mm to 87mm, and the minimum scale is 1 mm. The large test die and the standard test die are made of high-speed steel materials.
Although the embodiments of the present invention have been described above, the description is only for the convenience of understanding the present invention, and the present invention is not limited thereto. It will be apparent to persons skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
