[0002] Asphalt concrete is a structural form widely used in the field of road engineering, and is widely used in highway engineering, municipal road engineering, and airport flight areas.

[0003] Asphalt concrete is generally composed of hot mix asphalt mixture. The asphalt mixture is formed into an asphalt structure through mixing, transportation, paving and rolling. The uniformity of the asphalt mixture has a significant impact on the quality of the asphalt concrete structure.

[0004] At present, in the laboratory mix design stage before large-scale asphalt pavement construction, there is a lack of standardized and standard asphalt structure evaluation methods and means. Generally, experienced technicians judge the uniformity of the future structure through the cross-section of the indoor molded specimens. Because the molding method of indoor specimens is quite different from the on-site molding method, the evaluation effect is not good; or the uniformity of the formed structure is judged through the test section, but its economy and timeliness are poor. That is, there is a lack of molding devices that form asphalt structures with asphalt mixtures similar to those on the construction site to simulate the paving and molding of asphalt mixtures on the construction site.

[0005] Therefore, in view of the above shortcomings, the present invention urgently needs to provide a paving and forming simulation device for asphalt mixture. Summary of the invention

For ordinary technicians in this field, the specific meanings of the terms in the present invention can be understood according to specific circumstances.

[0045] like Figure 1 As shown, a specific embodiment of the present invention provides a paving and forming simulation device, comprising:

[0046] A machine base 1, wherein the machine base 1 is provided with a mounting portion and a forming mold placed on the mounting portion;

[0047] The spreader 2 is slidably mounted on the machine base 1. The spreader 2 is provided with an inner cavity for carrying materials and a fabric seam connected to the inner cavity. The fabric seam is located above the forming mold and is suitable for spreading fabric into the forming mold when the spreader 2 slides.

[0048] The vibrator 3 is connected to the spreader 2 and is suitable for spreading and compacting the material in the molding mold.

[0049] The machine base 1 is a bearing structure and is used to bear the mounting portion, the forming mold, the spreader and the vibrator. Specifically, the spreader is slidably mounted on the machine base and is used to evenly distribute the material in the inner cavity downward into the forming mold through the cloth seam at its bottom during the sliding process. The width of the forming mold is greater than the width of the cloth seam. It is arranged on the mounting portion and is located just below the spreader, suitable for receiving the distributed material. The vibrator is connected to the rear of the spreader, and it slides with the spreader, and spreads and compacts the material after the spreader distributes the material into the forming mold.

[0050] The device simulates the asphalt mixture paving and molding process at an actual construction site. The spreader 2 is used to spread the material into the molding mold, and the vibrator 3 is used to spread and compact the material in the molding mold. The asphalt structure specimens thus produced have good uniformity, and the paving effect of the mixture can be intuitively judged.

[0051] In a specific embodiment of the present invention, the forming mold includes a first tray, the mounting portion includes a first paving platform, and the first paving platform is also provided with a limiting portion that is adapted to stop the outer periphery of the forming mold at its periphery.

[0052] Specifically, Figure 1As shown, the first paving platform is a rectangular platform fixed to the machine base and arranged along the sliding direction of the spreader, and along the sliding direction, the end of the first paving platform is recessed downward to form a groove for accommodating the first tray, and the side wall of the groove serves as a limiter to define the first tray. The bottom surface of the spreader is placed on the first paving platform, and the first paving platform is used to seal the cloth seam. Once the spreader slides to the groove, that is, slides above the first tray, the cloth seam opens and the material is placed in the first tray, and then vibrated and compacted by the vibrator. The first tray is suitable for preventing the asphalt mixture paving simulation from contaminating the machine base, thereby realizing the reuse of the device.

[0053] At this time, the height of the first tray 4 is less than the height of the groove, preferably less than the height of the material to be paved. The height of the first tray 4 is less than the height of the groove, which can prevent the spreader 2 from being stuck by the side wall of the first tray 4 when sliding to the forming mold to spread the material on the first tray 4.

[0054] In a specific embodiment of the present invention, the first pallets are of multiple types, and each type of the first pallet has a different height specification; the mounting portion also includes a first lifting mechanism matched with the first paving platform.

[0055] Specifically, in the present embodiment, the first paving platform is connected to the first lifting mechanism, and is lifted and lowered in the machine base by the first lifting mechanism. Each first pallet has the same dimensions except for the height. The first paving platform is a lifting structure suitable for placing first pallets of different heights, thereby simulating the formation of road surfaces of different thicknesses. At this time, the limiting portion includes an end stop bar 15 and a side stop bar 16, the end stop bar 15 is suitable for stopping at both ends of the first pallet 4, the side stop bar 16 is suitable for stopping at the side of the first pallet 4, and the height of the end stop bar 15 and the side stop bar 16 are both less than the height of the first pallet, so as to prevent the limiting portion from affecting the downward vibration of the vibrator.

[0056] The first paving platform 11 can be raised or lowered by adjusting the height of the first lifting mechanism 12, so that first pallets 4 of different heights can be placed.

[0057] In a specific embodiment of the present invention, the first tray is a rectangular tray, and the number of the first trays of each height specification is 3, and the three first trays are arranged in sequence along the sliding direction. Specifically, the three first trays 4 are arranged in sequence along the sliding direction. Specifically, the three first trays are assembled in sequence and have substantially the same size as the mounting portion, wherein the first first tray is suitable for receiving unqualified head materials, the third first tray is suitable for receiving unqualified tail materials, and the second first tray is suitable for making asphalt structure specimens.

[0058] In the above embodiment, the rutting test specimen is formed by the first tray.

[0059] In a specific embodiment of the present invention, the first paving platform is provided with a through groove on the inner edge of the limiting portion, and the mounting portion also includes a second paving platform located below the first paving platform and corresponding to the position of the through groove; the molding mold also includes a second tray with a through hole on the bottom surface and a cylindrical tube with an inner diameter larger than the size of the through hole.

[0060] This embodiment is suitable for forming a Marshall test specimen. Specifically, a circular slot adapted to the cylindrical barrel is provided on the second paving platform, the lower end of the cylindrical barrel is fixed in the circular slot, and the upper end matches the position of the through hole of the second tray, which is suitable for allowing the material placed in the second tray to flow into the cylindrical barrel through the through hole to form a cylindrical Marshall test specimen.

[0061] In a specific embodiment of the present invention, the cylindrical barrels are of multiple types, each of which has different height specifications; the mounting portion further includes a second lifting mechanism matched with the second paving platform. The second lifting mechanism is used to adjust the height of the second paving platform to be suitable for mounting cylindrical barrels of different height specifications.

[0062] Further preferably, there are not only a plurality of cylindrical tubes of different height specifications, but also a plurality of cylindrical tubes of different diameter specifications, so as to produce test pieces of different sizes.

[0063] In a specific embodiment of the present invention, the vibrator includes a vibrating part and a compacting plate; the vibrating part is connected to the spreader; the compacting plate is located below the vibrating part and connected to the output end of the vibrating part, suitable for vibrating and compacting materials. Specifically, the vibrating part includes a driving motor and an eccentric wheel, the driving motor is elastically arranged in the vertical direction, and the eccentric wheel is arranged on the output shaft of the driving motor, suitable for rotating in a vertical plane to drive the driving motor to vibrate up and down. When the eccentric wheel rotates, centrifugal force is generated because its rotation axis and center are no longer in a straight line, and because the driving motor is elastically connected in the vertical direction, it can move up and down, thereby causing the driving motor and the eccentric wheel to reciprocate up and down driven by the centrifugal force, thereby achieving vibration to spread and compact the material in the groove.

[0064] In a specific embodiment of the present invention, the spreader is provided with a running wheel and a driving motor connected to the running wheel, and a running track is provided on the machine base, and the running wheel runs on the running track under the drive of the driving motor. Preferably, the spreader runs on the running track under the drive of the driving motor, and the speed of the running process is controllable, and the material spread in the first tray or the second tray is evenly distributed.

[0065] In a specific embodiment of the present invention, the travel track is a rack provided on both sides of the paving chassis, and the travel wheel is a pair of gears provided on both sides of the paving machine, and the gears mesh with the racks. The travel track can also be a tooth groove provided on the machine base and parallel to the traveling direction of the paving machine. In this case, the travel wheel is provided on the bottom surface of the paving machine and meshes with the tooth groove. Of course, other driving modes are also possible.

[0066] In a specific embodiment of the present invention, the paving and forming simulation device further includes a distribution hopper 5, which is slidably mounted on the upper end of the spreader 2 and communicated with the inner cavity of the spreader 2, and is suitable for uniformly feeding materials into the inner cavity of the spreader 2. Preferably, the distribution hopper 5 includes a connected rectangular structure and a funnel structure, wherein a flat plate is extended on each side of the rectangular structure, and the two flat plates are respectively overlapped on a pair of long sides of the upper edge of the spreader 2, and are suitable for driving the distribution hopper to slide on the upper end of the spreader 2 through the extended flat plate; a valve is provided below the funnel structure, which is suitable for controlling the discharge through the valve. The distribution hopper 5 is used to receive external materials, and slide on the spreader 2 to make the materials fall evenly into the inner cavity of the spreader 2, thereby making the materials evenly distributed in the spreader 2. The outside of the spreader 2 and the distribution hopper 5 is also provided with an insulation layer, which is suitable for keeping the spreader 2 and the distribution hopper 5 warm, so as to prevent the material temperature from dropping too fast and solidifying.

[0067] In a specific embodiment of the present invention, the paving and forming simulation device further includes a distribution hopper 5, which is slidably mounted on the upper end of the spreader 2 and communicated with the inner cavity of the spreader 2, and is suitable for uniformly feeding materials into the inner cavity of the spreader 2.

When it reaches the junction of the two trays, it stops vibrating, and the paving and compaction are completed. The remaining residue is recovered, and the rutting plate specimen that has been paved and compacted is taken out. If necessary, further processing is performed to complete the uniformity evaluation.
