Technical Field

[0001] The present application relates to the technical field of road facilities, and in particular to an asphalt concrete pavement. Background Art

[0002] Road lighting refers to the lighting set up for roads and their ancillary facilities. It is used to improve the safety of vehicles and pedestrians at night and prevent traffic accidents. Reasonable settings can improve traffic conditions, reduce driving fatigue, increase road capacity, and effectively reduce traffic accidents.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 To Attachment Figure 4 This application is described in further detail.

[0029] Reference Figure 1 , the embodiment of the present application discloses an asphalt concrete pavement, comprising a plurality of continuous road sections 1 and warning strips 2. The warning strips 2 are arranged in a uniform array on the side edges of the road section 1, and warning strips 2 are provided on both sides of the road section 1, and an interval for vehicle safety is formed between two continuous warning strips 2. The warning strip 2 comprises a tape box 3 and a reflective strip 61. The tape box 3 is installed in the road section 1. An observation groove 32 is provided on the side of the tape box 3 close to the road section 1, and the observation groove 32 is provided along the length direction of the road section 1. The angle between the direction in which the observation groove 32 is provided and the upper surface of the road section 1 is greater than fifteen degrees and less than ninety degrees. The observation groove 32 is covered with a light-transmitting strip 4, and the reflective strip 61 is provided in the tape box 3, and the position of the reflective strip 61 corresponds to the observation groove 32.

[0030] Reference Figure 1Specifically, the road section 1 includes a surface layer 11, a base layer 12 and a subbase layer 13 from top to bottom. Among them, the surface layer 11 is the part that directly contacts the wheels, and is required to have sufficient strength and flatness. It is paved after mixing materials such as asphalt concrete and asphalt macadam. The base layer 12 is the supporting structure of the surface layer, which is required to have sufficient strength and stability. It is paved after mixing materials such as cement stabilized macadam, lime fly ash stabilized macadam and so on. The subbase layer 13 is a transition layer between the base layer and the soil subgrade, which plays the role of transferring loads and diffusing stress. It is paved with materials such as graded macadam or gravel. In special cases, the layers can also be increased or decreased as needed. It should be noted that in the design of the pavement structure, it is also necessary to consider issues such as the connection and drainage between the layers to ensure the stability and durability of the pavement. Furthermore, the road section 1 is set on the foundation soil. The soil needs to be compacted before paving, and the construction inspection standards are used to screen the locations where settlement may occur, and special treatment is performed.

[0031] Reference Figures 2 to 4 Specifically, the warning tape 2 further includes a roller 6 and a control component 7. The roller 6 is rotatably connected to the tape box 3, and the reflective strip 61 is attached to the surface of the roller 6. The control component 7 is arranged in the tape box 3 to control the rotation of the roller 6. When the roller 6 rotates to a certain angle, light can be irradiated onto the reflective strip 61 through the observation slot 32. The reflective strip 61 reflects the light, thereby providing the outline of the road section 1 to remind the driver of the distance between the driver and the edge of the road, thereby improving safety.

[0032] Furthermore, the reflective strip 61 is preferably made of a high-brightness reflective lattice.

[0033] Reference Figure 3 and Figure 4Furthermore, the tape box 3 is in the shape of a long strip, and the tape boxes 3 are arranged at intervals along the length direction of the road section 1. A rotation groove 31 is provided in the tape box 3 along the length direction, and the observation groove 32 is connected to the rotation groove 31. The reflective strip 61 is attached to the surface of the roller 6 by a strong adhesive, and the reflective strip 61 is arranged along the length direction of the roller 6. The warning tape 2 also includes a photosensitive member 5, and a sinking groove 33 is provided on the upper surface of the tape box 3. The photosensitive member 5 is arranged in the sinking groove 33, and the sinking groove 33 is covered with a hard transparent sheet 331. Light can be irradiated onto the photosensitive member 5 through the transparent sheet 331, and the transparent sheet 331 plays a role in protecting the photosensitive member 5. The photosensitive member 5 is a photoresistor, and the photosensitive member 5 converts light into an electrical signal. The photosensitive member 5 is linked to the control component 7, and the control component 7 receives the electrical signal sent by the photosensitive member 5 to control the rotation of the rotating shaft 64. When the photosensitive member 5 is exposed to light (especially sunlight), the photosensitive member 5 controls the control assembly 7 to start, rotate the roller 6, and make the reflective strip 61 deviate from the observation slot 32, thereby preventing the reflective strip 61 from being exposed to sunlight for a long time and causing the reflective strip 61 to age. When the light intensity of the photosensitive member 5 decreases, the photosensitive member 5 controls the control assembly 7 to rotate the roller 6, so that the reflective strip 61 corresponds to the position of the observation slot 32, so that the vehicle light is reflected to show the edge of the road.

[0034] Furthermore, a timing module may be added, which supplies current to the photosensitive element 5 according to the sunrise and sunset conditions, thereby preventing the photosensitive element 5 from misjudging the light intensity and closing the reflective strip 61 at night.

[0035] Reference Figure 3 and Figure 4 Furthermore, the warning strip 2 further includes a photovoltaic strip 62, and a photovoltaic groove 63 is provided on the surface of the roller 6 along the length direction, and the photovoltaic strip 62 is arranged in the photovoltaic groove 63. The photovoltaic strip 62 is arranged at intervals from the reflective strip 61, and the photovoltaic strip 62 can be displayed in the observation groove 32 after the roller 6 rotates, so as to receive sunlight to charge the control component 7.

[0036] Reference Figure 3 and Figure 4 Furthermore, a chamfer 34 is provided at a corner of the belt box 3 close to the road surface and away from the soil, and the observation groove 32 is provided on the outer surface of the chamfer 34. A limit groove 321 is provided on the inner walls on the upper and lower sides of the observation groove 32, and a limit strip 41 that can slide in the limit groove 321 is provided on both sides of the light-transmitting strip 4. The light-transmitting strip 4 is limited by the cooperation of the limit groove 321 and the limit strip 41. Furthermore, a refractive groove 42 with the same radius as the roller 6 is provided on the side of the light-transmitting strip 4 close to the roller 6. When the light enters the light-transmitting strip 4 and irradiates the reflective strip 61, the light is reflected by the arc-shaped reflective strip 61 and then refracted by the refractive groove 42. The diffuse reflection range of the reflected light is larger and the field of vision is clearer. Furthermore, there is a distance between the surface of the light-transmitting strip 4 and the extension surface of the outer wall of the belt box 3, and the light-transmitting strip 4 is slightly sunken in the observation groove 32.

[0037] Reference Figure 3 and Figure 4 Further, the control component 7 includes a power supply 71, a worm wheel 72, a worm 73 and a driving member 74. A rotating shaft 64 is provided at both ends of the roller 6, and the roller 6 is rotatably connected to the tape box 3 through the rotating shaft 64. The rotating shaft 64 at one end of the roller 6 is coaxially connected to the worm wheel 72. The driving member 74 is a stepping motor, and the driving member 74 is arranged in the tape box 3, and the output end of the driving member 74 is connected to the worm 73, and the driving member 74 drives the worm 73 to rotate. The worm 73 is vertically rotatably connected in the tape box 3. The worm wheel 72 is meshed with the worm 73. The power supply 71 is arranged in the tape box 3, and the power supply 71 supplies power to the driving member 74. The photosensitive member 5 controls the power supply 71 to supply power to the driving member 74; during the day, sunlight shines on the photosensitive member 5, and the photosensitive member 5 causes the driving member 74 to drive the worm 73 to rotate, thereby causing the worm wheel 72 meshing therewith to rotate, so that the roller 6 rotates, and the photovoltaic panel is rotated to the observation slot 32, to be exposed to light, and the light energy is converted into electrical energy and stored in the power supply 71; at night, when the sunlight disappears on the photosensitive member 5, the driving member 74 is started here, and the roller 6 is rotated, so that the photovoltaic panel is offset, and the reflective strip 61 corresponds to the observation slot 32.

[0038] Reference Figure 2 and Figure 4 Furthermore, the warning tape 2 also includes a plug-in drill 8, which includes a tip 81, a rod 82 and an end block 83. The diameter of the end block 83 is larger than the diameter of the rod 82. A plurality of slots 35 are provided on the surface of the tape box 3 along the length direction, and the slots 35 vertically penetrate the tape box 3. The tip 81 of the plug-in drill 8 passes through the slots 35 and enters the road section 1 until it enters the base layer 13. The end block 83 is used to facilitate hammering. A plurality of countersunk grooves 351 are provided on the surface of the tape box 3, and the countersunk grooves 351 are connected to the corresponding slots 35. The countersunk grooves 351 can accommodate the end block 83, and the end block 83 is immersed in the extended surface of the surface of the tape box 3.

[0039] The implementation principle of an asphalt concrete pavement in the embodiment of the present application is:

[0040] During paving, the soil is compacted, and the subbase layer 13, the base layer 12 and the surface layer 11 are laid in sequence on the surface of the soil to form a road section 1. The belt boxes 3 are arranged at intervals on the edges of both sides of the road section 1. The belt boxes 3 and the road section 1 are fixed by inserting the dowel 8.

[0041] At night, the reflective strip 61 is at the observation slot 32. When a vehicle passes by, the light shines through the observation slot 32 onto the reflective strip 61. The reflective strip 61 reflects the light, thereby showing the edge of the road to remind the driver of the driving range. During the day, the photosensitive element 5 controls the power supply 71 and turns on the driving element 74, so that the roller 6 rotates, the reflective strip 61 shifts, and the photovoltaic strip 62 corresponds to the observation slot 32. While using light energy to supplement the power supply 71, it can prevent the reflective strip 61 from being continuously exposed to sunlight, which causes aging, and increases the service life of the warning tape 2.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
