Abrasion test wheel, asphalt pavement anti-slide performance testing device and method

Abstract

The invention relates to an abrasion test wheel, and an asphalt pavement anti-slide performance testing device and method. The abrasion test wheel is used for an asphalt pavement anti-slide performance test, and comprises a wheel body. The wheel body is provided with a silicon carbide layer and a rubber layer. The silicon carbide layer is installed along a circumferential direction of the wheel body, the rubber layer is installed along the circumferential direction of the wheel body, and the silicon carbide layer and the rubber layer are parallelly installed. The abrasion test wheel is capableof achieving the effect of compacting a rut sample, and the function of polishing aggregate on the surface of the rut sample, and beneficial to improvement of testing efficiency, and saving of testing cost. The asphalt pavement anti-slide performance testing device and method are capable of simulating a decay condition of real asphalt pavement anti-slide performance, and providing an effective measure for asphalt pavement anti-slide performance research.

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...

AI Technical Summary

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
