Embodiment Construction
[0018] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] In order to achieve the purpose of the present invention, as figure 1 As shown, in one of the embodiments of the present invention, an improved asphalt mixture rutting test device is provided, including:
[0020] Rack 10;
[0021] The support assembly includes a guide rail 30 and a support frame 31, the guide rail 30 is fixedly arranged on the frame 10, and the support frame 31 is provided with a support frame gas channel and is slidably arranged on the guide rail 30;
[0022] The rolling assembly includes a rolling frame 40, a rolling wheel 41, a trolley 42 and a displacement sensor 43. The rolling frame 40 is fixedly arranged at the bottom of the casing 20, and the rolling wheel 41 is arranged on the rolling frame 40 and its axis is in line with the rolling wheel. Elastic connectors (not shown in the figure) are arranged between th...

The invention discloses an improved asphalt mixture wheel tracking test device. The device comprises a machine frame, a bearing assembly, a grinding assembly, a conveying assembly and a gas source. The bearing assembly comprises a guide rail and a bearing frame, the guide rail is fixedly arranged on the machine frame, and the bearing frame is provided with a bearing frame gas channel and arranged on the guide rail in a sliding mode. The grinding assembly comprises a grinding wheel frame, a grinding wheel, a trolley and a displacement sensor. The conveying assembly is in transmission connection with the bearing frame. A gas outlet of the gas source is connected with the bearing frame gas channel. According to the improved asphalt mixture wheel tracking test device, asphalt mixture samples are placed on the bearing frame, the gas source is connected with the bearing frame gas channel, and asphalt mixtures are directly heated. Compared with the prior art, a box body structure is omitted, and cost is saved; meanwhile, the conveying assembly is in transmission connection with the bearing frame, the bearing frame is driven to move back and forth so that the whole asphalt mixture samples can be ground, the high-temperature wheel tracking resistance of the asphalt mixtures can be measured, grinding pressure of the grinding wheel is not affected by the conveying assembly, and testing accuracy is guaranteed.
Description
technical field [0001] The invention relates to a rutting test device, in particular to an improved asphalt mixture rutting test device. Background technique [0002] At present, the rutting tester is mainly used in the rutting test to roll and form the asphalt mixture sample, record the deformation curve of the asphalt mixture sample along with the rutting, and use it to determine the rutting resistance of the asphalt mixture sample ability. [0003] In the prior art, it is necessary to heat the box during the test to check the deformation of the asphalt under high temperature. The box structure has a large area, takes up a lot of space, and has a high cost. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides an improved asphalt mixture rutting test device. In order to achieve the above object, technical scheme of the present invention is as follows: [0005] The invention provides an improved asphalt mixtu...
