Problems solved by technology

Considering the complex wear requirements, the existing devices cannot meet the requirements due to their simple functions
In addition, the one-way linear wear device has a very low wear efficiency due to the stroke, which is also a very large limitation.

Abstract

The invention discloses a rapid pavement abrasion test device which comprises a base, an abrasion wheel, an abrasion wheel bracket, a sample tray and a controller. A linear motion mechanism and a sliding rail are arranged on the base, a sliding block is arranged on the sliding rail, the sample tray is simultaneously connected with an output part of the linear motion mechanism and the sliding block, the abrasion wheel bracket is arranged above the base, a stand column is arranged at one end of the base, and a connecting end of the abrasion wheel bracket is hinged with the stand column; and an abrasion motor is arranged on the abrasion wheel bracket. The abrasion wheel is arranged at a suspended end of the abrasion wheel bracket. The abrasion motor drives the abrasion wheel to rotate. The device can be used for accurately and quickly simulating the abrasion process of the surfaces of various pavements such as an asphalt pavement and a cement pavement indoors, and is used for evaluating the change of the surface structure of the pavement under the repeated action of tires and the influence on the surface skid resistance and other properties of the pavement; and a basis is provided forpavement design based on consideration of the surface structure and the surface skid resistance of the pavement.

Description

technical field [0001] The invention belongs to an indoor simulation test device for pavement surface wear and then function attenuation, in particular to a road surface rapid wear test device. Background technique [0002] Due to insufficient anti-skid performance of the road surface, the proportion of traffic accidents has increased significantly, and the insufficient anti-skid performance of the road surface is mainly due to the repeated action of vehicle loads, which leads to the gradual reduction of the surface structure of the pavement, which makes the surface anti-skid performance gradually attenuate until it cannot meet the requirements for driving. Safe skid resistance requirements. Therefore, in the design stage, it is necessary to start with the pavement structure, materials and technology, and design pavement structures and materials that meet the anti-skid requirements during the service life. The realization of this goal is largely due to the ability to estima...
