Problems solved by technology

[0003] The inventor believes that during the experiment, the rolling wheel exerts pressure on the asphalt material during the rolling process, driving the asphalt material to surge and accumulate to the edge, causing the asphalt material to easily overflow from the test mold, affecting the movement of the rolling wheel, and causing the experiment inaccurate result

Embodiment Construction

[0039] With the large-scale construction of highways in our country, the performance of asphalt pavement has been paid more and more attention. The rutting test is a method to evaluate the ability of asphalt mixture to resist plastic flow deformation under specified temperature conditions. At present, my country has included the rutting test in the ministerial specification. Through the reciprocating relative motion between the plate-shaped test piece and the wheel, the test block is Rutting occurs as a result of compaction, shear, push and flow under repeated loads of the wheel. The rutting test is an engineering test method, and the test results can be used to establish empirical formulas to guess the rutting depth of asphalt pavement, or to detect the rutting resistance of asphalt mixture.

[0040] The following is attached Figure 1-10 The application is described in further detail.

[0041] The embodiment of the present application discloses a rutting sample forming mach...

Abstract

The invention relates to a rut sample forming machine which comprises a workbench. One side of the workbench is provided with a mounting frame and a first driving part used for driving the mounting frame to slide, the mounting frame is provided with a mounting block and a second driving part used for driving the mounting block to slide, and the mounting block is rotatably provided with a rolling wheel. A rectangular placement groove is formed in the middle position of the workbench, and a test mold is detachably arranged in the placement groove. The two sides of the placement groove are each provided with a discharging groove, and the sides, close to the placement groove, of the discharging grooves are connected with the placement groove. During an experiment, the test mold is placed in the mounting groove, the mounting frame is moved to the position above the test mold, then the mounting block is driven to drive the rolling wheel to move downwards, pressure is applied to an asphalt material in the test mold, the asphalt material is rolled, and when the asphalt material in the test mold overflows outwards, the asphalt material enters the discharging grooves in the two sides, a situation that overflowing asphalt materials make contact with the rolling wheel to affect movement of the rolling wheel is effectively avoided, and the experiment accuracy is improved.

Description

technical field [0001] The present application relates to the field of experimental equipment, in particular to a rutting sample forming machine. Background technique [0002] The rutting sample forming machine is mainly used for rolling and forming asphalt mixture during rutting test, and can also be used for making wheel-rolling samples for other physical performance tests of asphalt mixture. [0003] The inventor believes that during the experiment, the rolling wheel exerts pressure on the asphalt material during the rolling process, driving the asphalt material to surge and accumulate to the edge, causing the asphalt material to easily overflow from the test mold, affecting the movement of the rolling wheel, and causing the experiment The result is inaccurate. Contents of the invention [0004] In order to improve the accuracy of the experiment, the application provides a rut sample forming machine. [0005] A rutting sample forming machine provided by the applicatio...
