Abstract
The utility model discloses a marshall stability testing device for a high-strength asphaltic mixture, which comprises a digital display compression testing machine, two testing molds, a cushion block, a marker pen and two straight rulers, wherein the two testing molds are installed right above a lower pressure plate of the digital display compression testing machine and are positioned under an upper pressure plate; the two testing molds are mutually buckled up and down to form a hollow column body; a test piece is arranged between the two testing molds; and the cushion block is arranged between an upper testing mold and the upper pressure plate of the digital display compression testing machine in a cushioning manner. The cushion block is a cylinder, and the diameter of the bottom surface of the cushion block equals to the diameter of a round pressure bearing bulge formed at the center part of the top part of each marshall testing mold. With the help of the common marshall testing molds and the cushion block, the marshall stability testing device can test the stability of the high-strength even ultrahigh-strength marshall test piece according to the method described in the concrete implementation manner. The marshall stability testing device has the advantages of simple structure and high practicability, and is convenient to operate. The testing molds adopt hollow half-terete marshall testing molds.
Description
Technical field
The utility model relates to a kind of high-strength asphalt compound Marshall stability proving installation, and this device is used for the test specimen that exceeds common Marshall stability appearance range ability is carried out the Marshall stability test.
Background technology
Marshall Test is used to measure bitumen mixture specimen failing load and non-deformability.At present; Common asphalt Marshall stability tester is made up of parts such as pressure head, two semicircle pressing molds, heavy frame, base, data recording equipments; But generally about 40kN, this can meet the demands for common marshal piece the range of common Marshall stability appearance; But the high strength marshal piece for some special-purpose can not satisfy the test request to its degree of stability.Therefore, a kind of to be directed to the proving installation that the test specimen that exceeds common Marshall stability appearance range ability carries out degree of stability test be very to be necessary in exploitation.
Summary of the invention
Defective or deficiency to above-mentioned prior art existence; The purpose of the utility model is; A kind of high-strength asphalt compound Marshall stability proving installation is provided; This device can be realized the degree of stability test of high-strength even the strong marshal piece of superelevation by common Marshall die trial and cushion block according to the method for describing in the embodiment.The utility model is simple in structure, and is easy to operate, practical.
In order to achieve the above object, the utility model adopts following technical solution:
A kind of high-strength asphalt compound Marshall stability proving installation is characterized in that, comprises digital display pressure testing machine, two die trials, right cylinder cushion block, marking pen and two rulers; Wherein, Two die trials be installed in the digital display pressure testing machine lower platen the center directly over, and be positioned at the below of top board, two die trials interlock up and down and form a column cavity; Between two die trials test specimen is installed, above the center of top board of die trial and digital display pressure testing machine between be lined with cushion block.
The utility model also comprises following other technologies characteristic:
Said digital display pressure testing machine is selected SYE-2000 type pressure testing machine for use.
The half-terete Marshall die trial of hollow is selected in said die trial for use.
Said cushion block is a right cylinder, the equal diameters of the circular pressure-bearing projection of the bottom surface diameter of this cushion block and Marshall die trial top center.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Below in conjunction with accompanying drawing and embodiment the utility model is further explained.
Embodiment
As shown in Figure 1; The high-strength asphalt compound Marshall stability proving installation of the utility model; Comprise digital display pressure testing machine 1, two die trials 2, cushion block 3, marking pen and two rulers, wherein, two die trials 2 be installed in digital display pressure testing machine 1 lower platen 6 the center directly over; And be positioned at the below of top board 5; And two die trials 2 interlock up and down and form a column cavity, between two die trials 2 test specimen are installed, above the center of top board 5 of die trial 2 and digital display pressure testing machine 1 between be lined with cushion block 3.
Digital display pressure testing machine 1 is selected SYE-2000 type pressure testing machine for use.

The range of ruler is 50mm, and the range of ruler is to confirm according to the size of the lower platen 6 of digital display pressure testing machine 1.
It is following to the step that test specimen carries out the Marshall stability test to use the utility model:
1, asphalt is prepared into the marshal piece 4 of given size;
2, find out the center of the lower platen 6 of digital display pressure testing machine 1 with two rulers;
3, use center with the same method mark 2 of step 1;
4, test specimen 4 is laterally placed two semicircle die trials 2, make test specimen 4 receive lateral confinement, fixing between two die trials 2; The die trial 2 that will have test specimen 4 then is placed on the center of the lower platen 6 of digital display pressure testing machine 1 according to centre mark;
5, cylinder cushion block 3 is held in place on the circular projection of center of top of die trial 2 of top, top board 5 centers, lower platen 6 centers that guarantee die trial 2, cushion block 3 and digital display pressure testing machine 1 are point-blank;
6, rotate the rotating disk on digital display pressure testing machine 1 top, digital display pressure testing machine 1 top board 5 is just contacted with cushion block 3;
7, under set point of temperature, start digital display pressure testing machine 1 and pressurize according to given pace; When the pressure value of digital display pressure testing machine 1 demonstration no longer raise, this numerical value was the Marshall stability of the test specimen of being tested, the kN of unit.
