Description

Technical Field

[0001] The utility model relates to the technical field of road engineering, in particular to an abrasion simulation device for asphalt pavement penetration material. Background Art

[0002] The materials for asphalt pavement penetration are mainly liquid petroleum asphalt, emulsified asphalt or coal tar asphalt. The penetration layer is formed by pouring these materials onto the base layer to make the asphalt surface layer bond well with the non-asphalt base layer, thus forming a thin layer of transparent base. This pre-treatment can increase the adhesion between the base layer and the asphalt surface layer, fill the pores on the surface of the base layer, and combine the loose aggregates on the surface of the base layer together. When vehicles travel on the asphalt pavement, the wheels will wear on the penetration layer material. Generally, a simulation device is used to simulate the wear of the asphalt penetration layer material by the tire under actual driving conditions.

[0003] The existing Chinese patent with announcement number CN217654939U discloses a wear simulation device for the surface functional layer of an asphalt pavement, including a simulation device body, a connecting rod, a standard tire, an asphalt pavement functional layer and a base. A connecting rod is installed at the left end of the simulation device body, a standard tire is installed at the left end of the connecting rod, an asphalt pavement functional layer is paved at the lower end of the standard tire, the asphalt pavement functional layer is connected to the base through a fixed structure, and a heat dissipation component is connected to the right end of the simulation device body.

[0004] Although the above scheme facilitates the replacement of the functional layer of the worn asphalt pavement and improves efficiency, the device does not simulate sufficiently and lacks simulation of the high temperature conditions of the asphalt pavement in summer and the slippery conditions on rainy days, resulting in a low degree of simulation and affecting the simulation effect. Therefore, it does not meet the existing needs. In this regard, we propose a wear simulation device for asphalt pavement penetration materials. Utility Model Content

[0005] The purpose of the utility model is to provide a wear simulation device for asphalt pavement penetration material, so as to solve the problem that the wear simulation device proposed in the above background technology lacks simulation of the high temperature condition of the asphalt pavement in summer and the slippery condition in rainy days, resulting in low simulation degree and affecting the simulation effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an asphalt pavement permeable layer material wear simulation device, comprising a base, a lifting plate is arranged directly above the base, an asphalt pavement permeable layer is arranged at the upper end of the base, a simulation device body is arranged directly below the lifting plate, a standard tire is arranged on one side of the simulation device body, and the standard tire is located at the upper end of the asphalt pavement permeable layer, and the standard tire is connected to the simulation device body through a connecting rod;

[0007] It also includes a first sprinkler seat, which is arranged at the front side of the upper end of the base, and a second sprinkler seat is arranged at the rear side of the upper end of the base, and the lower ends of the first sprinkler seat and the second sprinkler seat are both provided with a plurality of nozzles distributed in a rectangular array, and one end of the first sprinkler seat and the second sprinkler seat are both installed with a valve;

[0008] It also includes heating blocks, which are arranged on the front and rear sides of the lower end of the asphalt pavement penetration layer.

[0009] Preferably, the valve and the nozzle are connected via a water pipe.

[0010] Preferably, electric telescopic rods are installed on both sides of the base, and the output ends of the electric telescopic rods are connected to the lifting plate.

[0011] Preferably, a group of drainage grooves are provided on the front and rear sides of the upper end of the base, and each group of drainage grooves has two drainage grooves.

[0012] Preferably, a motor is provided inside the asphalt pavement permeable layer, and the output end of the motor is connected to the simulation device body.

[0013] Preferably, a heat dissipation fan is provided at a middle position of the upper end of the base.

[0014] Preferably, a rectangular baffle is provided on the outer side of the upper end of the base.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model is provided with a second sprinkler seat at the rear side of the upper end of the base. When performing simulation, an external water pipe can be connected through a valve. By starting an external water pump, water can flow into the water pipe, and the water can be sprayed downward through a nozzle, so that the water can be sprinkled on the upper end of the asphalt pavement permeable layer, thereby simulating the wet road surface on rainy days, making the simulation of the simulation device more sufficient and improving the simulation effect.

[0017] 2. The utility model provides heating blocks on the front and right sides of the lower end of the asphalt pavement permeable layer. After the heating blocks are started, the asphalt pavement permeable layer above can be heated, thereby simulating high temperature conditions in summer. In addition, through the first sprinkler seat, a rainy day simulation can be performed under high temperature conditions in summer, making the simulation more sufficient and further improving the simulation effect.

[0018] 3. The utility model has electric telescopic rods installed on both sides of the base. When multiple simulations are performed, the asphalt pavement permeable layer will not have the same thickness. Starting the electric telescopic rods can make the lifting plate move up and down, and the lifting of the lifting plate will drive the simulation device body to make the standard tire move up and down synchronously, so that the standard tire can better fit the asphalt pavement permeable layer of different thicknesses, making the simulation effect sufficient and practical.
