Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a device for detecting the ability of a road surface to resist water erosion. Background Art

[0002] Water damage is one of the major early-stage defects of asphalt pavements. Water damage can be summarized as the flaking of asphalt from the stone surface caused by surface water infiltration. The damage is caused by surface water seeping into the road interior, causing the asphalt-stone interface to gradually lose adhesion, which in turn triggers the asphalt film to detach (peel) from the stone surface, resulting in granulation and loosening of the asphalt mixture, and subsequently forming potholes and deformations in the asphalt pavement. Therefore, during the asphalt pavement design phase, accurately evaluating the water-resistant nature of the asphalt-stone interface to guide pavement material selection is crucial for improving the performance and extending the service life of asphalt pavements.

[0003] my country's "Test Procedures for Asphalt and Asphalt Mixtures in Highway Engineering" (JTG E20-2011) stipulates the use of water immersion to simulate water erosion of pavement materials. The asphalt / stone bond interface's resistance to water erosion is evaluated by observing the asphalt peeling rate (percentage of peeling area) on the stone surface after water damage (T0616-1993). It also qualitatively requires that the asphalt peeling rate be "visually observed by two or more experienced testers and the average value is taken."

[0004] However, when the color of stone and asphalt is similar, it is impossible to effectively distinguish between stone and asphalt by naked eye observation alone, and thus it is impossible to accurately calculate the asphalt peeling area on the stone surface, thereby reducing the accuracy of the evaluation of the water erosion resistance of the asphalt / stone interface.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 4 As shown, the embodiment of the present utility model provides a device for detecting the water erosion resistance of a road surface, comprising:

[0027] The box body 21 has an opening on the front side and is hinged with a door 22. The door 22 and the box body 21 are both made of opaque material to prevent external light from entering the box body 21. A mobile power supply 13 and a data interface 12 are also provided on the outside of the box body 21. The mobile power supply 13 is electrically connected to the camera 6 and the ultraviolet lamp 4 for powering the camera 6 and the ultraviolet lamp 4. The data interface 12 is electrically connected to the camera 6.

[0028] The storage table 5 is fixed at the middle of the bottom of the box body 21;

[0029] The first adjustment rack is arranged on the rear side wall of the box body 21. The first adjustment rack is provided with a camera 6 and is placed directly above the storage platform 5.

[0030] A second adjustment rack is provided on each of the left and right side walls of the box body 21 , and each second adjustment rack is provided with an ultraviolet lamp 4 .

[0031] When performing the water immersion method, a fluorescent tracer is added to the asphalt. After the water immersion method is completed, the stone is placed on the storage table 5, and the angle of the ultraviolet lamp 4 to irradiate the stone is adjusted to make the fluorescent tracer in the asphalt on the surface of the stone glow. Then, the position of the camera 6 is adjusted so that the stone is within the shooting range of the camera 6. Then, the hatch 22 is closed, and the camera 6 is used to shoot a fluorescent image of the stone surface. The external device is connected to the data interface 12, receives the fluorescent image and calculates the difference between the surface area of the stone and the glowing area. The asphalt peeling area can be known. In this way, the asphalt and stone can be automatically and accurately distinguished by shooting the glowing area of the stone surface by the camera 6. No manual observation is required, and the asphalt peeling area on the stone surface can be accurately calculated.

[0032] Among them, the first adjustment frame includes a first vertical frame 11, a first horizontal frame 10 and a transverse moving portion. A first slide groove 16 is vertically opened on one side of the first vertical frame 11 close to the storage platform 5. A first slider 15 is provided at one end of the first horizontal frame 10 and is slidably set in the first slide groove 16. The first slide groove 16 is a T-shaped slide groove, and the first slider 15 is a T-shaped slider adapted to the first slide groove 16. A locking tooth 17 is provided at the front opening of the first slide groove 16. A hook 14 is provided on the upper side of the first slider 15. The first horizontal frame 10 is provided with a plurality of first through grooves that pass through from top to bottom;

[0033] The transverse movement part includes multiple shoulder screws 7 and a fixing plate. The camera 6 is fixed on the lower side of the fixing plate. Multiple anti-loosening nuts 8 are fixed on the upper side of the fixing plate. The shoulder screws 7, anti-loosening nuts 8 and the first through grooves correspond one to one. The lower end of the shoulder screw 7 passes through the first through groove from top to bottom and is threadedly connected to the anti-loosening nut 8.

[0034] Due to the irregularity of the stone to be measured and its size cannot be determined, in order to ensure that the entire stone is within the shooting range of the camera 6 while not making the captured image of the stone too small, it is necessary to adjust the height and position of the camera 6. When adjusting the height of the camera 6 on the y-axis, first separate the hook 14 from the engaging tooth 17, and then move the first horizontal frame 10 up and down. After determining the height, engage the hook 14 with the engaging tooth 17 to fix the height of the first horizontal frame 10. When adjusting the horizontal position of the camera 6 on the x-axis, support the camera 6 upward so that the lock nut 8 contacts the lower side of the first horizontal frame 10, and then translate the camera 6 back and forth. After determining the position of the camera 6 on the x-axis, turn the shoulder screw 7 so that the upper head of the shoulder screw 7 contacts the upper side of the first horizontal frame 10, and clamp the first horizontal frame 10 by the lock nut 8 and the upper head of the shoulder screw 7 to fix the position of the camera 6.

[0035] The second adjustment frame includes a second vertical frame 2, a second horizontal frame 1 and a connector. A second slide groove is vertically opened on one side of the second vertical frame 2 close to the storage platform 5. A second slider is provided at one end of the second horizontal frame 1 and is slidably set in the second slide groove. The second slide groove is a T-shaped slide groove, and the second slider is a T-shaped slider that matches the second slide groove. A coupling tooth 17 is also provided at the opening of the second slide groove, and a hook 14 is also provided on the upper side of the second slider.

[0036] A second through groove running through the front and back is provided on the side of the second transverse frame 1. The connector includes a clamping ring 3 and a hinged rod 19. The clamping ring 3 is sleeved on the ultraviolet lamp 4. Two connecting plates 18 are symmetrically arranged on the outside of the clamping ring 3 and are respectively placed on the front and back sides of the second transverse frame. The hinged rod 19 is fixed in the second through groove. The two ends of the hinged rod 19 are respectively movably passed through the two connecting plates 18 and are threaded with fastening nuts 20.

[0037] The method for adjusting the height of the ultraviolet lamp 4 on the y-axis is similar to that of the camera 6. First, separate the hook 14 from the engaging tooth 17, and then move the second horizontal frame 1 up and down. After determining the height, engage the hook 14 with the engaging tooth 17 to fix the height of the second horizontal frame 1. The ultraviolet lamp 4 only needs to have a UV light coverage range larger than the surface of the stone for irradiating the stone. At the same time, the intensity of the ultraviolet light irradiated on the surface of the stone can also be adjusted at any time. Therefore, there is no need to adjust the position of the ultraviolet lamp 4 on the x-axis. You only need to adjust the angle at which the ultraviolet lamp 4 irradiates the stone. At this time, you need to simultaneously rotate the fastening nuts 20 at both ends of the hinged rod 19 to separate it from the connecting plate 18. After adjusting the irradiation angle of the ultraviolet lamp 4, reverse the fastening nut 20 so that it conflicts with the connecting plate 18 to fix the irradiation angle of the ultraviolet lamp 4.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
