Problems solved by technology
Indoor simulation tests generally use rubber tires to load the rut specimens. However, this can only compact the rut specimens and it is difficult to effectively polish the surface aggregates, and it cannot simulate the decay of the anti-skid performance of the real asphalt pavement.
Moreover, the wear efficiency of rubber tires on the mixture rut specimens is low, and it usually requires long-term continuous operation to meet the test requirements

Embodiment Construction
[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening ele...

The invention relates to an abrasion test wheel, an asphalt pavement anti-skid performance test equipment and a method. The wear test wheel is used for asphalt pavement anti-skid performance test, including a wheel body, the wheel body is provided with a carborundum layer and a rubber layer, the carborundum layer is arranged along the circumference of the wheel body, and the rubber layer It is arranged along the circumferential direction of the wheel body, and the emery layer and the rubber layer are arranged side by side. The wear test wheel can not only achieve the effect of compacting the rut test piece, but also play the role of polishing the aggregate on the surface of the rut test piece, which is beneficial to improve test efficiency and save test cost. The asphalt pavement anti-skid performance test equipment and method can simulate the decay of the real asphalt pavement anti-skid performance, and provide an effective means for the research on the anti-skid performance of asphalt pavement.
Description
technical field [0001] The invention relates to the technical field of asphalt pavement skid resistance testing, in particular to an abrasion test wheel, asphalt pavement skid resistance testing equipment and a method. Background technique [0002] With the rapid development of road traffic, traffic safety issues are getting more and more attention from the society. The skid resistance of asphalt pavement is one of the key factors affecting traffic safety. Not only should the asphalt pavement have good skid resistance at the initial stage of construction, but also the asphalt pavement should have good skid resistance from the beginning of service until it is out of service. [0003] In recent years, how to simulate the long-term anti-skid performance decay of different asphalt pavements through experiments has become the focus of research on the anti-skid performance of asphalt pavements. At present, some researchers are still using the outdoor survey method. Although the o...
