Problems solved by technology

[0003] However, the test condition of the existing rutting simulation test device is only to adjust the test temperature, and the temperature is mostly only controlled at room temperature to 60°C, without integrating many other natural environmental factors, such as ultraviolet rays, rain, low temperature, changes in oxygen concentration, etc.
Therefore, the existing rutting simulation test device cannot obtain the data closest to the actual situation under the influence of the above-mentioned comprehensive environmental conditions, and the scope of application of the test results is greatly limited

Embodiment 1

[0038] according to figure 1 and figure 2 As shown, this embodiment is illustrated: a multi-functional rutting tester, which is composed of a test box, an industrial computer and a console, and a rutting test assembly, an ultraviolet lamp 2, a shower head 3, a refrigeration device 4, and a heater are arranged inside the test box 5. Temperature sensor 6, oxygen nozzle 7, nitrogen nozzle 8, oxygen concentration sensor 9 and water tank 10, the industrial computer controls the rutting test components through the program software, and the console is used to control the switch and spray of the ultraviolet lamp 2 in the test chamber. The spraying, temperature and oxygen concentration of shower head 3.

[0039] An insulation layer 1 is arranged on the outer wall of the test box. Ensure that the temperature of the test chamber is constant during the test.

[0040] The water tank 10 is used to collect the water sprayed by the shower head and discharge the water out of the test chamb...

Embodiment 2

[0066] Such as figure 1 As shown, as a conversion embodiment of embodiment 1, the height of the ultraviolet lamp described in the technical solution of the present embodiment can be adjusted, vertical rods 22 are arranged symmetrically on the top of the test box, chute 23 is set on the vertical rods 22, and the moving rod One end of 21 is placed in the chute 23, and the other end fixes the ultraviolet lamp 2.

[0067] The adjustable distance between the ultraviolet lamp 2 and the test piece 18 is 300-700 mm.

[0068] By adjusting the position of one end of the moving rod in the chute, the height of the ultraviolet lamp can be adjusted, and then the distance between the ultraviolet lamp and the test piece can be adjusted, so as to achieve the purpose of adjusting the intensity of ultraviolet light irradiated by the ultraviolet lamp on the test piece. In the rutting test, the tester can determine the distance between the ultraviolet lamp and the test piece according to the actu...

Abstract

The invention discloses a multifunctional rut testing instrument, and relates to a rut testing instrument. The provided multifunctional rut testing instrument solves the problem that the conventional rut stimulation testing devices cannot obtain the data that is most approximate to the actual data under comprehensive conditions. The rut testing instrument is composed of a testing box, an industrial computer, and a control table; a rut testing assembly, an ultraviolet lamp, a spraying nozzle, a refrigerator, a heater, a temperature sensor, an oxygen gas jet pipe, a nitrogen gas jet pipe, and an oxygen gas concentration sensor are arranged in the testing box, the industrial computer controls the rut testing assembly through program software, and the control table is used to control the switch of the ultraviolet lamp, the spraying of the spraying nozzle, the temperature, and the oxygen gas concentration. The provided multifunctional rut testing instrument can carry out stimulation tests under comprehensive environment with different sunlight strengths, rain water amounts, temperature ranges, and oxygen gas concentrations so as to obtain the asphalt road surface aging situation data, which is closest to the actual data, under the comprehensive conditions. The test results have a good adaptability, and thus the testing instrument is very helpful for the researches on the aging rules of asphalt road surface.

Description

technical field [0001] The invention relates to a rutting tester, in particular to a multi-functional rutting tester which simulates low temperature, sunlight, rain and oxygen concentration changes. Background technique [0002] At present, the known asphalt pavement rutting simulation test device is mainly composed of a test box and an industrial computer. The test box is composed of a power switch, a heater, a test wheel, a driving motor for the test wheel, a jack, a counterweight, a test piece fixing frame, a temperature sensor, a displacement sensor, a crank, and a box. Put the well-developed test piece into the test piece fixing frame and lock it. After the temperature is constant, use the hand crank to lower the counterweight so that the test wheel fully contacts the test piece, so that it is always in a downward pressure state. Adjust the displacement sensor up and down, and lock the displacement sensor. Start the industrial computer and click the test start button ...
