Embodiment Construction

[0049] Such as Figure 1 to Figure 3 As shown, the test device for the rolling time of the asphalt mixture of the present invention includes a storage tank 1, an insertion and tamping device, a temperature sensor, a data acquisition system 4 and an environmental chamber 5;

[0050] The storage tank 1 is a cylinder frame, which is composed of 8 vertical bars 2 and a bottom plate 3. The inner wall of the storage tank 1 is equipped with a grid; the grid plays a centralized role in fixing the asphalt mixture without affecting The asphalt mixture is in full contact with the simulated environment of the environmental chamber 5 during the experiment;

[0051] The inserting and tamping device comprises a circular pressing plate 13, one side of the pressing plate 13 has a handrail 10, and the other side of the pressing plate 13 has 9 evenly distributed tamping rods 11; compacted;

[0052] There is a stage 6 and a fan 7 at the bottom of the environmental box 5, and a fixed mount 12 an...

Abstract

The invention discloses a press bearing time tester for asphalt mixture, comprising a charging barrel, a tamping unit, a temperature sensor, a data acquisition system and an environmental cabinet, wherein the charging barrel is a cylinder which is provided with grid mesh on inner wall; the tamping unit comprises a pressing plate which is equipped with a handrail on one side and a tamping bar on another side; an objective table and a fan are arranged at bottom of the environmental cabinet, the objective table is provided with a holder and an anemometer, the holder comprises an upper bottom side and an lower bottom side which are connected by a reinforcing steel bar, the centre of the upper bottom side is a round open hole with the diameter equal to the external diameter of the charging barrel, the anemometer is closely arranged beside the holder and the fan faces the holder and the anemometer; thermal radiation light source is arranged on the top side in the environmental cabinet; and the temperature sensor and the data acquisition system are connected. The invention also provides a test method, comprising preparatory stage, test stage, and test data analysis stage. The invention has simple test and maintenance.

Description

technical field [0001] The invention relates to a test device, in particular to a device for measuring the rolling time of asphalt mixture and a test method thereof. Background technique [0002] The rolling time of the asphalt mixture refers to the time that the asphalt mixture passes from the mixing temperature to the temperature at which the rolling is terminated. Whether the asphalt mixture can be fully rolled is the key to ensure the quality of the asphalt pavement, and there must be enough rolling time. It takes time to complete. In addition, the rolling time of the same asphalt mixture paved at different times is significantly different. As a temperature-sensitive material, the temperature change of asphalt mixture is significantly affected by factors such as air temperature, wind speed, and mixture type. Therefore, according to the characteristics of the construction season and the composition characteristics of the mixture, determining the time for rolling is very ...
