specific Embodiment approach 1

[0025] Specific implementation mode one: refer to Figure 1 to Figure 5 This embodiment is described. This embodiment provides a road roller for positive texture forming of asphalt pavement, the main body frame 1 of the road roller, two steel wheels 2, a high-pressure air injection assembly 3 and a high-pressure liquid injection assembly 4;

[0026] The two steel wheels 2 are respectively mounted on the front and rear ends of the main body frame 1, and each steel wheel 2 is rotationally connected with the main body frame 1, and the high-pressure air injection assembly 3 is installed on the main body frame 1, and the high-pressure air injection assembly 3 The two spray ends of the high-pressure liquid spray assembly 4 are respectively set towards the outer surface of a steel wheel 2, and the high-pressure liquid spray assembly 4 is installed on the main body frame 1, and the two spray ends of the high-pressure liquid spray assembly 4 are respectively facing the outer surface of ...

specific Embodiment approach 2

[0030] Specific implementation mode two: refer to Figure 1 to Figure 5 This embodiment is described. This embodiment is to further limit the negative grain steel grain 21 described in the first specific embodiment. Pyramid holes spliced ​​together. Other compositions and connection methods are the same as those in Embodiment 1.

[0031] In this embodiment, the shape of the negative texture monomer is a positive quadrangular pyramid with the tip facing inward, and the side length L and height H of the bottom surface are selected according to the maximum particle size of the asphalt mixture gradation. When the maximum particle size is greater than or equal to 9.5mm, L is 2.36mm and H is 4.75mm; when the maximum particle size is less than or equal to 9.5mm, the texture of L is 1.18mm and H is 2.36mm is selected. This design can be effectively molded on asphalt pavement Reducing the embedding of aggregates while positively textured.

specific Embodiment approach 3

[0032] Specific implementation mode three: refer to Figure 1 to Figure 5Describe this embodiment, this embodiment is to further limit the main frame 1 described in the second specific embodiment, in this embodiment, the cockpit 12 is provided on the main frame 1, and the cockpit 12 is located at the main frame 1 at the center of the top, and the cockpit 12 is welded and fixed with the main body frame 1, and the cockpit 12 is provided with a controller. Other compositions and connection methods are the same as those in the second embodiment.

[0033] In this embodiment, the cockpit 12 can be used by the driver when working. In the cockpit 12, except the existing console for driving the road roller to and fro, a controller is also provided. 3 is connected to the start-stop end of the high-pressure liquid injection assembly 4, so that the driver can control the working status of the heating assembly 22, the high-pressure air injection assembly 3 and the high-pressure liquid inj...

Abstract

The invention discloses a road roller for positive texture forming of an asphalt pavement, belongs to the field of manufacturing of road rollers, and aims to solve the problems that the anti-skid performance of the road surface is weak and the safety of road traffic transportation cannot be fully guaranteed due to the fact that texture features cannot be controlled in the construction time of the conventional asphalt pavement. According to the road roller for positive texture forming of the asphalt pavement, the inherent thinking that the construction texture of the original asphalt pavement cannot be designed is broken through, the positive texture is given to the surface of the road, the friction between vehicles and roads is effectively improved, and the traffic driving safety is guaranteed; besides, the heating effect is realized, the steel wheel is heated through heat radiation, asphalt can be effectively prevented from being cooled and bonded, and during new road construction and road maintenance, a wheel face of a proper specification is selected and positive textures are manufactured according to the maximum gradation particle size of the asphalt pavement, and the positive textures are formed on the asphalt pavement during rolling through the negative texture steel wheel, larger friction force is provided for vehicle-road interaction, and the safety of the vehicle in the driving process is guaranteed.

Description

technical field [0001] The invention belongs to the field of road roller manufacturing, and in particular relates to a road roller used for forming the positive texture of asphalt pavement. Background technique [0002] With the application and promotion of asphalt pavement, asphalt pavement is often given priority when building or reconstructing high-grade pavement. In 2018, the death toll of traffic accidents in China was 63,194, causing direct property losses of about 1.4 billion yuan. According to relevant research, traffic accidents are mainly caused by improper operation of drivers and insufficient anti-skid performance of road surfaces. The Swedish National Road and Traffic Research Center studied the relationship between the friction coefficient of the road surface and the accident rate. Traffic accident rate dropped by about 60%. [0003] The problem of traffic safety has always been a difficult problem faced by all countries in the world. Because the texture of ...
