DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-4 As shown, an asphalt pavement testing machine includes a connecting ring 1, the bottom surface of the connecting ring 1 is fixedly connected to two vertical plates 10, the bottom surfaces of the two vertical plates 10 are commonly fixedly connected to an asphalt pavement contact seat 11, the connecting ring 1 can be supported by the asphalt pavement contact seat 11 and the vertical plates 10, and the device can be kept stable when in use, the inner wall of the connecting ring 1 is provided with an annular groove 9, and the inner wall of the annular groove 9 is slidably connected to two sliders 2.

[0024] The sides of the two sliders 2 that are close to each other are fixedly connected with a connecting cylinder 3, and the inner wall of each connecting cylinder 3 is rotatably connected with a rotating rod 8. The sides of the two rotating rods 8 that are close to each other are commonly fixedly connected with a measuring cylinder 5. A funnel 6 is provided above the connecting ring 1, and the bottom end of the funnel 6 is fixedly connected to the top end of the measuring cylinder 5. The funnel 6 allows the staff to add water to the inside of the measuring cylinder 5 to prevent water from spilling on the asphalt pavement. The bottom surface of the measuring cylinder 5 is fixedly connected with a control valve 16.

[0025] The bottom surface of the control valve 16 is fixedly connected to a telescopic hose 18, and the bottom surface of the telescopic hose 18 is fixedly connected to a water seepage cylinder 19. The inner wall of the asphalt pavement contact seat 11 is fixedly connected to two groups of support plates 14, and the side surfaces of the two groups of support plates 14 close to each other are fixedly connected to the outer surface of the water seepage cylinder 19. The water seepage cylinder 19 can be fixed by the support plates 14 to prevent the water seepage cylinder 19 from sliding and affecting the detection data during the water permeability test. The bottom surface of the measuring cylinder 5 is fixedly connected to a group of ring-arranged pull rods 15, and the bottom end of each pull rod 15 is fixedly connected to a metal counterweight ball 17.

[0026] In this embodiment, the outer surface of the asphalt pavement contact seat 11 is sleeved with two perforated weight rings 13, and the inner walls of the two perforated weight rings 13 are slidably connected with two groups of positioning rods 12. The bottom end of each positioning rod 12 is fixedly connected to the upper surface of the asphalt pavement contact seat 11.
